A change in your code or program can have an adverse effect on your existing functionality. The basic functionality should always be verified whenever you make code changes.
Regression testing is a type of testing which ensures that any change in the application code does not affect the old working code and its features. In software development, any change to the code with respect to enhancements, bug fixes, or new functionality might accidentally lead to new errors or the recurrence of old defects. So, it is always important to ensure that the application is working fine even after the changes. Hence, regression testing is highly essential when there is a continuous change in the application. Any software after changes should undergo regression testing. If not, the application might fail in the live environment.
At QAonCloud, we do regression testing for each code change or functionality change. We create regression test suites based on the business requirements, priority modules, important features, etc and execute them during every test cycle and ensure that the system is working as expected. We prioritize the test cases for the regression test suite based on the functionalities that are more important, functionalities that fail frequently, complex test cases, test cases that cover the recent code changes, etc.
Regression testing requires the execution of a set of test cases for every test cycle, which is a time consuming and tedious process. So, QAonCloud focuses on automating the regression testing efforts that would save time and costs.
We understand your priorities, list out the basic functionality cases, and automate the regression suite using opensource tools. We run a full regression suite to ensure complete functionality coverage after any server patches, code changes, and database upgrades of your code.
- We ensure that the addition of new code to your software does not affect the existing features by re-executing the full or partial selection of test cases.
- Manual/Automated scripts ensure all the existing functionalities are working fine.
- The Regression test suite is selected based on the frequently used functionalities, critical features, and also based on the business impact.
- We may also suggest automating the previously executed test cases, thereby saving time and money.
- Our team maintains and sends you the report for each regression cycle.
- "Performance Engineering in the Digital Era: After 2020, your business is either digital or does not exist. Yes, it is evident that digital presence has become the key to survival in the current era. COVID-19 has rapidly changed the way we work, communicate, and socialize while leaving us with the challenge of making significant changes in a matter of days. Take a glimpse of COVID-19 driven digital adoption rates. Why is Performance Important For Your products Today, most organizations have accelerated their pace of digital adoption irrespective of their understanding and outlook towards digital transformation in the pre-pandemic times. Although organizations are speeding up their digital initiatives and investing in relevant tools and technologies, there is not enough attention to the performance side of digital initiatives. If digital is a survival requisite, the digital application experience is a necessity for business reputation, resilience, ROI, and customer satisfaction. If an application has an amazing user interface and innovative features but lacks good execution - it is bound to fail. In a nutshell, digital transformation can be the front-facing need for businesses but performance is the driver that ensures the success of the digital transformation efforts of the organization. The Performance Engineering Perspective of Digital Transformation Gone are the days when software and application testing was all about checking functional bugs. Today, the non-functional elements like load handling, security and vulnerability issues, user experience are on the rise. Whether your team needs to serve more mobile users on an application, or you are shifting from an in-house cloud solution to a third-party solution provider, everything should be well tested, and optimized with the right strategy. What is Performance Engineering? Performance issues just don’t happen. They are designed within the application. Well, that is not because the software engineers are malicious, it’s because they are human beings. They make some assumptions about the software while writing the code. And it is not possible for them to know how the system will perform and where bottlenecks will turn up when they start coding the software. Here the concept of performance engineering comes into the picture. “Performance engineering is all about improving the speed and efficiency of the product while embedding the key performance decisions into design, architecture, and implementation.” The performance engineering process lets you understand the product fall-backs in the very early phase of the software development lifecycle. It allows seamless collaboration between tools, processes, and teams via continuous feedback loops while preventing expensive changes later down the line. A proactive focus will result in saving your valuable time and cost while boosting the value of the product, from business as well as user perspectives. How is Performance Engineering Different from Performance Testing? Key Performance Areas Performance Engineering Performance Testing Time to market Faster as the fallbacks are identified in the early stages. Slower as the testing is performed after the release of the product. Test coverage More time to work gradually as it is a continuous process. Limited validation scenarios due to budget and time constraints. Approach A proactive approach that works with development and testing parallelly. Reactive after other testing levels. Utilization High as the team works in collaboration. Low as different teams work on various tasks and cannot collaborate properly. Early detection of issues High as the issues are identified and resolved during the script development process. Low as issues are identified after the end of all other testing processes. Time dedication No requirement for dedicated time. Dedicated time is required for knowledge transfer as there is no or little collaboration among teams. Why Do You Need Performance Engineering? Software engineers have been stumbling over hundreds and thousands of assumptions since the dawn of programming. For example, ten years ago, an online airline ticketing system offered very limited services. You could only search for flights and buy tickets online, but only if you were on the right browser. Today, everything is so seamless. In addition to purchasing a ticket, you can check-in, book a seat, pay for additional baggage, choose a meal, manage your account, and much more. There is a basic need to support all popular browsers, mobile devices, as well as mobile apps. These new features and frameworks have to work well with the back-end code to manage the system while meeting all the performance requirements. A crash of even a few minutes can cause a loss of thousands or millions of dollars. While finding and resolving the source of error in a complex system can take a lot of time and cost. This means the managed performance of the application and user experience needs to be incorporated throughout the software lifecycle, not only when it is first launched. With a growing number of applications, performance engineering ensures regular testing, as well as on-demand testing to ensure the quality of the existing application as well as every additional integration. The performance engineering methodologies align perfectly with agile processes to address the issues earlier in the development process. Can Performance Engineering Replace Performance Testing? There is a lot more to performance engineering than the testing process. It enables you to understand how all the components of the system fit together, knowing what performance metrics matter, and building the right user experience right from the initial stage. Performance engineering practices are a broad set of processes as compared to testing. You can easily please customers, support employees, and boost revenues. Here's why performance engineering will never replace performance testing. 1. Vital for the bottom line Did you know that the average cost of network downtime is over $5,600 per minute and amounts to over $300,000 per hour? Until your site is up and running again, there are high possibilities that consider a switch to your competitor. The consistent performance support allows you to safeguard data loss and public embarrassment due to a system crash. 2. Time to monitor performance properly The performance testers lack the support to repair defective environments. While the overall performance is monitored from the initial stage of the development cycle. The performance engineering environment monitors the system to identify the scope of better experience and implement the required changes on a regular basis. 3. Objectivity and independence Just like you would not expect a writer to review their work, you cannot get the design and testing of the software application by performance testers. Here, the impartial insights are provided into the application to ensure the best-in-class performance. 4. Performance metrics Performance testing can track the server throughput, concurrent user loads, browser performance to assess the overall quality. But mostly, testers rely on their creativity and intelligence to match the expectations of end-users. Therefore, performance engineering has a phased approach to ensure a high-performing application in the long run. 5. Efficient reporting While the testers need to assess the performance and make reports, the performance engineering methods measure the experience of individual layers, including the web server, application server, network etc. When performance engineering is done right, it is surely going to improve the planning of deployment time with high-quality products. In addition, it reduces the business costs arising out of unforeseen issues. A clear and step-by-step testing approach ensures that organizations move towards better web applications and mobile experiences. The Right Approach to Performance Engineering The performance engineering practices should align well with the metrics that really matter to businesses. While testing identifies the gaps, the onus of architecting it correctly lies on the engineering team with proactive actions from the quality assurance team. Let us explore the standard approach to a performance engineering culture. Understanding of performance risks: It is important to understand the performance expectations of customers from the application. It helps in identifying the potential risks and assessing the damage it can cause. Then, these risks are ranked in terms of probability of the risk occurring, severity for proper resolution. Establishment of performance objectives: Set quantitative objectives to control and assess the efforts. However, it is important to set realistic objectives considering the number of requests received by the system. Set the parameters that matter: Consider the viewpoint of multiple stakeholders and accordingly, consider the parameters that matter to the customers and business. It is vital to ask pertinent questions related to response time, bottlenecks in a multi-user environment, etc. It helps in understanding the real user environment and its challenges to ensure a quality user experience. Early focus: The early focus on performance helps in gaining real-time insights into architectural issues, and optimize the multi-user application before it goes live. Besides faster deployment, it is extremely important to deliver uncompromised quality. Architecture assessment: As you implement performance engineering, it is also vital to assess the architecture. It is recommended to process the architecture based on reusability, reliability, scalability, and quick modification. Automation: Implementing automation throughout the testing process helps in getting faster and better performance results. You can yield better coverage by implementing the automation based on multiple scenarios the application might face. Don’t wait to start your performance engineering journey with QAonCloud.

Everyone wants to use mobile apps for their daily activities. But do you really need to download an app to own it? When you consider how easily and quickly you can install something like a flashlight app on your device, it makes you wonder about the benefits of keeping apps on your device. Well, it is unlikely that you will need every mobile app all the time. As long as you can access an app when you need it the most, what is the benefit of having it on your mobile and taking up the device space? Android Instant Apps is the answer to this dilemma. Since the launch of Instant Apps in May 2017, it has taken over the mobile app development world. But to be able to publish your app as an instant app, you need to conduct a Google play instant testing process. Whenever a mobile app is launched, the developer has certain goals such as generating user traffic, increasing revenues, getting high ratings, providing benefits to users, etc. Getting the app in front of a large audience could also be an important goal of your app. If you want to achieve a lot more than this, Android Instant Apps can help you big time. Instant app feature makes your mobile app discoverable from multiple locations such as – URLs, Google search results, social media posts, emails, YouTube comments, etc. Well, there are a lot of things to know about Instant apps and Google play instant testing. Let’s go step by step. What are Instant Apps? Instant apps are Android applications that need not be downloaded from the play store or installed on the user device. These apps are designed to save storage space on the device and deep link the users to the specific function of apps. Currently, they are only available for Android. It works as an instance of the app on the play store that can be used with a single click. This gives a native user experience without even downloading or installing the mobile app. The users can simply click on the “Try Now” button to start using the app. Use Cases for Google Play Instant Apps Once you build the mobile app and complete the process of Google play instant testing, you are all set to launch the instant app on the play store. When Android instant apps were announced, Google used a parking meter app as an example of their offerings. With this app, the users can immediately use the capabilities of the parking meter app without downloading, installing, or signing up. It delivers the opportunity to increase user engagement with the app and gain more installs after completing the Google play instant testing process. Such apps allow the users to try a particular app for a specific time without installing it and later decide whether to download and install the app onto their device or not. There can be many other use cases for instant apps with a completely native experience. Some of them are: Car parking solution Demo of image analytics app or a video Menu display of restaurant One time authenticators Game demo stage Location routine information Shopping and checkout at a virtual or physical store Why is Google Play Instant Testing Important? Instant apps have become the next great step in mobile development. At first sight, they don’t differ much from the conventional mobile apps as they look and function just like a mobile app. The major difference is that you don’t need to download or install them on your device. When the instant app testing is conducted, it ensures that all the necessary app functionality works perfectly without having to install the app from the play store. Let’s find out how Google Play instant testing helps: Ease of access Android instant apps allows the users to access and run apps instantly, without any installation hassles. The users can easily get a native Android experience from any URL – including social media, search engines, messaging, and other deep links. As soon as the link is clicked, the user will be redirected to the mobile web space where they can use the app features. This will provide a much better experience to the users as they won’t have to go through the whole process of searching and installing the mobile app. They can conveniently use all the features of the app with a single click. More creativity Now when the developers are well aware that the users can access the mobile apps before even installing them, they will be more focused on the creativity of applications. The developers have to introduce a “lite” version and get the mobile apps to pass through Google Play instant testing process to provide a better user experience. The users will be able to relish the new and improved mobile app experience. Save space Did you know that over 43% of users remove apps from their smartphones to free up storage space? (Source: Alligator Test). And once a mobile app is removed from the phone, it is rarely reinstalled. So, the storage concern is very important for users and instant apps can help a big-time here. Getting through the process of Google Play instant testing ensures that your mobile app consumes less space without compromising with features. Better app engagement Mostly, searching, downloading, installing, and executing the registration process of a mobile app takes much more time than using the application itself. This can lead to a lack of user engagement since users lose the enthusiasm to use the app before even reaching its useful content. Not anymore. Instant apps, on the other hand, provide the opportunity to try the features of the app instantly without any additional time and effort of users. It helps users to decide whether they want to use the application or even download it. Thus, the users will be significantly more engaged with the application. More valuable users and applications As there is no need to install the app to know the usability, the users can easily sneak into the features of the application. And once they are satisfied, they can install the application for future use. When you get your Google Play instant testing completed, the users can easily gain access to the app without downloading, experience the user interface, try its core features, and create an instant opinion about it. This way, only the valuable users will stick to your mobile app, and for the long term. It will also help in increasing the user retention rates as only the satisfied users will be downloading the application and the chance of application abandonment will decline subsequently. Increased app visibility Most of the developers face the challenge of getting their mobile app listed at the top of app stores and increasing the number of app downloads. The great advantage of Instant apps is that the access is not limited only to the Google Play store. Instead, the link to access the instant app can be published on many other platforms resulting in more ways to promote the app, better app visibility, and more downloads. Key Tips to Consider While Conducting Google Play Instant Testing Process Well, you need to consider a lot of things in mind before processing the development of instant apps. Have a look at a few important points of consideration. 1. Choose the new version of Android Studio To develop an instant app, the foremost thing to be considered is that it requires Android 5.0 (API level 21). It is recommended to take the help of the latest Android Studio version for building and testing the instant apps. This service of Android app development enables you to drive higher application installs and build a strong market presence. 2. Reduce the app size conveniently There are many good reasons why users prefer to use instant apps but reduced app size remains the top priority. Hence, it is important to keep the size of apps in check before launching the lite version of your mobile app. While Google play instant testing always ensures to keep the app size in check, the preferable size should not exceed 4 MB for apps and 10 MB for games. If the size of your app range from 4 MB -10 MB, the users can leverage the “Try Now” button and experience the app conveniently. 3. Decide the type of instant experience Delivering an excellent user experience is one of the primary motives of an instant app. For basic experience, allow users to click on the “Try Now” button or a website banner to try an instant mobile app. For an enhanced experience, market the app on multiple platforms in the form of advertisements, messages, QR codes, etc. Enable the instant experience today Instant apps have been a revolution in the era of mobile app development. And the best part is that a specific link can open the app while minimizing the cost and time of development. On one hand, the users can understand the features and functionalities of the app for free, while on the other hand, it provides better chances of user conversion and retention to app developers. Google is also gearing up to give multiple instant app experiences for a single app in the future. Undoubtedly, the future of trial versions or demos is through Google play instant testing.

- "Virtual Reality: a modern technology Virtual Reality is a powerful emerging medium that promises to change user interaction with digital technologies. It is now possible for individuals to interact in any virtual reality environment using VR goggles or mobile devices. Various forms of non-immersive, semi-immersive, and fully immersive simulation technology transform many industries at B2B and B2C levels. At its inception, Virtual Reality was envisioned purely for consumer use cases, such as the gaming and entertainment industry. However, it has also proved surprisingly helpful in various ways for the medical sector, defence sector, and even industrial sector in recent years. The use cases are only set to increase as it gains mainstream adoption. VR's rapid growth in popularity, and the nascent stages of the technology, throw unique challenges for companies from the developers' point of view. Lately, head-mounted displays have been introduced with eye detecting cameras and high-accuracy object detecting sensors. People want to try these features, especially the gaming community. Developers and startups need to constantly adapt and innovate if they're going to stay relevant. As a result, VR applications have evolved a lot within few years and continue to rapidly grow for the foreseeable future. The most prevalent issue in VR apps is their Quality Assurance. The old traditional methods of 2D testing are no longer usable in 3-D VR testing. The industry has failed to establish a standard testing framework and testing technology due to the constant flux. We will go through the various tools available to test VR Apps and how you can effectively test your VR applications. Tools for functional testing of Virtual Reality applications There are specific tools that are necessary for VR application testing. These are: SteamVR Performance Tool It is a fundamental tool to evaluate compatibility. It displays the compatibility of your PC with the VR app. 3600 EYETRACKERTM software solution This software tracks your eye movement and lets the user see anywhere in the environment. It also enables the audience to see the user's point of view and the direction in which the user is looking. It extrapolates the user's field of view. Unity testing tool Unity is an excellent tool to start with. It is for unit testing to focus on a particular object in your virtual reality environment. One can also use a google plugin called Google Instant Preview with Unity. It enables you to see the building unity in the editor. You can directly run your game, and it's visible to everyone around you. Desired output formats A detailed Heat map with interactive controls Video in the 2D environment from 360 content Relive personal viewer experience through VR headset. How to test your VR app 1. Define the Objectives There should be clarity in creating the aim for the functional testing of the VR apps. The testing must ensure the input and output parameters are fulfilled. Some of the most common objectives are: Ensuring expected behaviour: The test performed on the VR app must ensure that the app is running as per requirements. That is, it is functioning as expected. However, VR apps are often complex, with many hidden bugs. It also depends upon the human-machine interface to fulfil the objective. Manual Testing: To ensure human interaction and evaluate how well the user is adapting, utilizing, and immersing in the VR app. Environment effects: The objective must also ensure the effectiveness of the real-world environment in the virtual world. The user should feel a difference between Reality and virtuality. He also needs to judge how close to the actual environment that virtual environment is. This objective should be able to depict that difference. Automating specific test: To process the high degree of interaction, evaluation of inputs then sorting and evaluation of outputs, automating a particular part of the test becomes essential. Create a list of desired user experiences that we want from the app and what the publisher will gain from the app 2. VR Testing Methods Trial and Error approach Virtuality reality apps are based on Reality. So, it relies on human perception. It means – detecting bugs, glitches, issues with the app; the "reality" aspect is subjective to that individual. It also means that testing results will vary from person to person. The best way is to test the behaviour of the application through testing tools. Dedicated testing tools like the SteamVR performance tool ease the process of testing. Recording sessions The recording sessions offer a better understanding of the view and human –interaction with Reality. It gives deep insight into debugging. It can be shown to the people outside to get the necessary help. Sometimes, the bugs or glitches. Letting other testers see the recording sessions will allow you to spot errors in later stages. Automation testing tools There are aspects of virtual reality apps that testing tools have drawn better results. Automated testing tools are helpful in UI tests and performance tests. The existing tools in the market boast the testing phase and ensure the quality of your VR app. Testing of motion sickness in VR apps Reality sickness is one of the significant challenges in the virtual reality environment. The human brain does not fully immerse into another reality. The reality movement directly leads to motion sickness; it is vital to make sure that even the very essential mind can withstand the effects of VR apps. User feedback Feedback reporting tools ease your work. Suppose you release the app in the market. These feedback tools will help you to discover more bugs and glitches in the app. It will also aid in enhancing the quality of the application. UI test automation framework For VR automation, we recommend AirTest. It is one of the best open-source frameworks and it is built for VR gaming apps, where you get an automated testing framework. It is cross-platform and it supports Windows, native apps, iOS and Android. AirTest includes app installation, assertion, simulated input and so forth. You can perform image recognition technology to locate and identify UI elements. Automate tests on games without code injections. You can see the results in HTML reports. It's easier to find failed tests quickly. Integration Test This test requires more skills than automating unit test. Two or more objects are combines and test in the simulated environment or a specific scenario. These kinds of tests are created and integrated into the test engine. This engine requires multiple systems, more skills and resources. End to End Testing / QA testing It means a full playthrough of the VR app that needs to be tested. It is done manually as well as automatically. But the automated version of QA still needs much input to become more usable. Things to consider before automating your VR Test cases Some of the test scripts are already available. The Quality assurance process can use those existing test scripts. It is a heuristic method to find repeatable areas of the build. Those areas can be automated with optimum effort. A fully developed VR app can be tested by using source control and continuous integration. Consider the scale of your system, and size of the team and the type of app before leveraging the source control and continuous integration. You can take references from Git and Mercurial. Always test the 2D version of your app. It saves time and accelerates the process of debugging. Use telemetry data – it is helpful in long term work. Especially when you analyze a specific error, telemetry data should be relevant to the user walkthrough of the app and the user flows of a successful playthrough. Whenever a new change happens, the compiling code and running the asset build on the CI systems detect those issues. The diligent method is to tell your team in advance about those errors and avoid meeting those conflicts in advance. This way, the team can move forward, avoiding any potential test blockers. Monitor performance through ON-device automation. Monitoring will tell you the root cause of any issue. New changes can also harm the computer's performance; On-device automation can helps us in monitoring the long term performance and detecting the bugs. Simulate the trigger by giving commands. In simple words – tell the character to reach a particular spot "A" from another spot "Y". Monitor the performance characteristics on ADB and also keep a checklist to run and check necessary events throughout the app. Tools to performance and analyzing your VR Apps OVR Metrics tools It analyses the mobile application with real-time graphic overlay. It provides data on heat, frame rates, GPU/CPU throttling values. Logcat It collects VrApi logs. One can collect system logs with its command line. The Quality assurance team can take a close look at the app performance and device setting. Ovrgupprofiler It accesses real-time data of GPU pipeline metrics and provides stage tracing with the CLI tool. GPUsystrace It includes information about the timing data of the steps of rendering pipelines as well as the information on the rendered stages. RenderDoc It is a tool that is the best solution for capturing frames and analysis. It is a graphic debugger tool. It is compatible with multiple graphical APIs and development platforms. Unity Profiler It records various aspects of the app's performance. It can store 300 frames of any app and shows you detailed information about every frame. One can explore the script code also. Final words It is up to the Quality assurance team to pick the best tools for testing. However, some of the testing tools can accelerate the process of testing and debugging. One must learn to run few automation scripts on the available device to test. Once the test is done, one can start justifying more hardware. Consider bandwidth after testing; your team need to analyze and report based on these findings. Begin with the unit testing as it is the fundamental method and then consider the further stages of software testing. As VR apps and their testing are considered in their infant stage, we hope that more tools will be developed to automate and accelerate the entire process."

The success of foldable devices is directly affected by the quality of mobile apps. But the unique features and characteristics of the foldable screen present challenges for app developers. Bug-prone apps commonly plague Foldables mobiles due to fragmentation of screen and ultimately results in negative reviews. And any negative experience will be associated with the quality of mobile phones and not any specific mobile app. This is where you need efficient app testing for foldable devices. The key to testing apps on foldable devices is testing the functional and user experience-focused tests. Key requirements for foldable apps development Since the popularity of foldable devices is increasing tenfold, it has become vital to consider improving practices for seamless mobile app experiences on foldable devices. Planning for mobile app development for a single screen is very different from mobile apps for foldable devices. Here are some important aspects to consider while developing and testing apps for foldable screens. Infographics: Key considerations for the development and app testing for foldable devices Key features to consider for app testing for foldable devices Bigger screens, handy experiences, richer and immersive user experiences, multitasking with multiple widows, less power-hungry display, and more. Certainly, foldable smartphones offer a lot of opportunities. But planning for developing and testing mobile apps for foldable devices is quite different from single small screen devices. Let’s dig deeper into some of the most important features for mobile apps for foldable devices. 1. Continuity App continuity issues are one of the major mobile app challenges for foldable devices. This feature is all about switching from one state to another based on the screen orientation. The mobile app needs to follow the continuity and offer a seamless user experience in both screen modes. The user should be able to easily switch from one mode to another without having to open the app again and again. Also, when they do that, the app should switch to the expanded screen without missing a beat. 2. Resizability The mobile apps should be compatible with smaller as well as larger screens essentially. The resizability factor must be considered at the time of app testing for foldable devices. Based on the type of fold and functionality of the smartphone, the mobile app designs and interface should also fit perfectly. Additionally, the shape and size of foldable devices should remain the same while consuming media through smartphones. 3. Multi-Window Ability With the multi-window feature, the users can run multiple apps at the same time. However, facilitating this feature can be tricky. Earlier, while using multiple apps on the same screen, only the active app runs while others would be paused. But with foldable devices, users can run multiple apps on the same screen at the same time. So, it is vital to consider the multi-window compatibility at the time of app testing for foldable devices. The mobile apps should be developed in a way that multitasking with different screens should be easy and seamless for the users. 4. Support for Multiple Screens The mobile app developers should always consider the compatibility with two or more screens at a time. The primary and secondary screen can be decided while developing the app, but it should resume to either of the screen sizes, the text as well as the configuration without any glitches. 5. Multi-resume Another important feature needed for mobile apps for foldable devices is multi-resume. The apps resume as per the user requirements when the screen is folded or unfolded. While the dual-display improves the efficiency, it creates many issues for the accessibility of features and functionalities of the mobile app. But if the app testing for foldable devices is conducted appropriately, your mobile app can seamlessly function in the multi-window mode without any glitches. 6. Aspect Ratio Since Apple has not yet entered into foldable devices, most of the phones in this segment are Android. And building mobile apps for Android phones comes with aspect ratio challenges. There are numerous mobile devices with different screen sizes. And the difficulties in the case of foldable devices increase drastically. The app testing for foldable devices should ensure that different aspect ratios are adjusted according to multiple devices.

- "Every work sphere in technology is evolving rapidly. The term " Agile Methodology " came into the limelight, that focuses on continuous improvement and sustainable economic growth. Well, it may not be new. Agile testing is a part of Agile methodology that refers to the testing process of the entire software development life cycle. This approach helps testers and developers collaborate and communicate, thereby eases the process of identifying defects as early as possible and thereby creates a valuable product. What is Agile in Testing: Agile testing is an iterative and incremental process of the software development lifecycle. Unlike the traditional software testing methodologies (like the waterfall method), where testing comes only at the end of the cycle, this approach supports continuous testing and DevOps. These are very crucial to improve the quality of a product. Agile Testing will start even before the dev team starts the development and happens continuously as the features are added. Testers aim to write as many testcases as possible in each iteration, and these agile tests are prioritized just like the user stories. Throughout the product life cycle, regular interactions between developers, customers, managers, stakeholders, and QA/testing teams happen.Agile Testing Methods The following are the most crucial Agile testing methodologies that support agile processes- 1. Test-Driven Development (TDD) In this agile testing method, coding, testing, and design go hand-in-hand. The development cycle starts with writing a unit test & then developers write a code and edit the code until the unit test passes. The software requirements are converted to testcases at the beginning of the SDLC before the development of software. We can apply TDD on unit and component tests. The tests are usually done with the help of automation testing tools. The main aim of the TDD methodology is to make sure all the features are working as they should be. 2. Acceptance Test-Driven Development (ATDD) In this method, the development of the product happens as per the end-user requirement. ATDD is a customer-centric approach, where the developer team, the testing team, and the customers create acceptance tests from the end-user perspective. The developers then develop the code according to the Acceptance tests created. 3. Behaviour Driven Development (BDD) Behavior-driven development is a refined & augmented approach of TDD and ATDD as the development team writes the code according to the test cases created. Unlike ATDD, this approach focuses on the identification of business needs and goals. During the testing process, testers implement behaviors that contribute directly to the business goals. As this agile testing method pays close attention to the distribution of behavior, we can save the time spent on testing. 4. Exploratory testing Exploratory testing focuses on interacting with an already released application. It allows testers to play around with the software and use it chaotically without writing any scripts. Testers list out all the possible user behaviors, use their creativity to take actions that can break the software. Testers usually focus on areas or scenarios that pose high value for users. But there will not be any detailed documents that describe how the exploratory tests are conducted. Testers report only the defects to the clients 5. Session-based testing The session-based testing methodology aims to ensure that the software product is tested entirely and comprehensively. It’sverysimilar to that of exploratory testing, except the tests, are conducted during Time-boxed sessions. Session-based testing combines exploratory testing, accountability, and control. This method helps testers to structure the tests and perform them during uninterrupted sessions. In this approach, testers create test charters. This charter contains details like what to test and test reports which allow testers to document what they discover during a test. It will, in turn, help in getting rid of hidden bugs & defects in the product. Why Agile Testing Methods are a Success Agile in the software industry came into the picture because of its process of streamlining and improving. The approach paves an integration among developers, testers, product owners, and customers. However, the target goal for all of these teams is a quality project delivered through iterative sessions. Subsequently, agility is making its place in every new digital workplace, and even organizations now find it an excellent way to transform their project in general. To understand better, here are some of the benefits of agile methodology. A. Build Your User Base Agile methodology is not just valuable for the developers but also communicates the core concept to the users. With the completion of every iteration, a helpful product comes as a result. So, at any moment, you can easily decide to launch the halfway product to your customers. It helps build up your user base or test your logic and theory.2; B. Flexible to Update Ideally, not every development methodology is created to accommodate the mid changes. But Agile testing offers the scope of change whenever and wherever necessary. There is always a need to update software projects either with the customer needs or the market trends. And so Agile embraces the idea of change that occurs mid-project. C. Early Risk Management Have you ever thought about what the concept of beta releases is? Well, a product should be tested early in the process by the users and stakeholders. It will help in identifying the feature defects and issues in the production process itself. By adopting those changes, it's easy to mark a successful project delivery. D. Cost under Control For most instances, clients step back regarding the features that the client had requested during the initial stages. Consequently, the product launches early, and clients have to pay less price. It is the case of fixed-budget projects. At the same time, Agile is quite flexible in this scope. With Agile methodology, the client has to pay only for what they need without any risks of uncertainty. E. Double-Check on Quality We should integrate Agile Testing Methods throughout the entire development project. Delivering consistently tested products assures high-end quality and takes much less time trying the product as a whole. By Conducting frequent tests on the product, Incremental releases happen. Even after the product's release, it's much easier to locate flaws and improve them before the final launch. Downsides of Agile Testing Methods Though there are multiple advantages of using Agile testing, its demerits cannot be unseen. Let's check a few of them. A. Delay in Project Delivery Undoubtedly, we cannot ignore the power of Agile Testing Methods. But, if you see, much time and effort are consumed in fixing small bugs and rolling out software releases post minor updates. It will increase regression bugs which ultimately impact the day of final project delivery. B. Lack of Adaptability Agile testing methods are perpetual, implying that testers have to switch to new test strategies that arelikely to change. Most of the time, good test strategies have a short life span and are just done away for the sake of Agile Project Delivery. Let's wrap it up To conclude, the complexity of software products is constantly increasing and henceforth the development lifecycle. Upgrading the development strategies is not just enough to sustain the overall growth. Testing approaches also need to be evolved with the advancement in the development process. Agile Testing Methods brings a new age for testing professionals, focusing on intelligent, effortless, and high-end deliverables. In an Agile Testing approach, developers and testers collaborate to work on the final delivery of the product. Testers must develop corrective feedback for the intermediate software product during the complete development cycle at different stages. Moreover, the Agile Testing Methods should always align with the customer requirements collected at the beginning of any software project. In a few words, we can say that Agile testing is a long and continuous goal rather than being a sequential process."
