Importance of Black Friday Sale

Black Friday is the first Friday after Thanksgiving as it marks the start of the holiday shopping season. It is a ‘Major Payday’ for e-commerce stores. They know that their customers are eagerly waiting for it and they’ll try to get the best out of the sale day. e-commerce businesses must focus on delivering the best user experience to the customers. If the application is not user-friendly, especially during the sales day, customers might move on to other stores who might be your biggest competitor. So, if you don’t want to lose your customers to your competitors, then you must perform eCommerce application testing to gain competitive edge.

Why is e-commerce application testing important?

In the excitement to increase their sales, eCommerce stores often fail to test their applications. During a BF sale, there will be an unprecedented volume of customers using the store at the same time, especially using the mobile application. Thousands will be adding the same product to their cart and thousands will be checking out at the same time, crippling the payment gateways. And finally, this overload will crash the application. 

Bob Buffone, the CTO of Yottaa says, “If you have not load tested your site at five times normal traffic volumes, your site will probably fail,” 

Yes, and many popular sites have failed during the most important sale day of the year. Any store that undermined eCommerce application testing has faced its fair share of losses and we’ve listed some of them in the next section.

Examples of stores that crashed during black friday sales


JCrew, the popular American Clothing and Apparel store faced technical difficulties during BF 2018. Customers complained that they could not add items to their cart, the website was glitchy and had poor User-experience. JCrew responded that they faced some technical difficulties due to the demand and traffic surge and apologized to customers. It was reported that they lost $775,000 in sales due to the crash.

John Lewis 

John Lewis is a popular Homeware and Fashion store and it faced the wrath of BF traffic back in 2015. It was reported that the websites had a massive spike of 660% in traffic. This overwhelmed the website and it crashed during the busiest time of the sales. Black Friday crash costed them a $2.8 Million loss in sales. 


Gymshark is a Fitness apparel and accessories brand that crashed during BF 2015. The website crashed for 8 hours straight due to the heavy load on the website. They didn’t take any chances after the incident, they migrated their website from Magento to Shopify, to handle the traffic surges. But the damage was already done. Shopify said, “The failure cost Gymshark an estimated $143,000 in lost sales. Worse, it also cost the company the trust it had spent years earning from customers expecting a great experience.”

e-commerce application testing: Making an app ready for Black Friday Sales

Online stores tend to have a false belief that their application won’t crash so they voluntarily avoid testing their stores. This has cost them millions in sales and your application could be next if eCommerce application testing isn’t done prior to D-day

Here are the six types of testing that you must perform on an e-commerce application.

Functional testing 

Functional testing is carried out to identify the glitches and bugs that can hinder the customer experience. It is performed to verify if all the functionalities of the application are performing as per the intended requirements and deliver the best experience to customers. It includes testing the,

  • Login and Signup systems
  • Search and multiple filters
  • Product and Cart pages
  • Offers and discounts 
  • Payment gateways
  • Order confirmation and tracking systems 

Usability testing 

Testing the user-friendliness of an application is crucial. Reports say that 88% of customers will not return to the website after a bad experience. Considering the fact that almost 80% of customers access eCommerce stores using mobile applications proves that usability testing is not a neglecting factor. Usability testing helps in checking whether the site has,

  • Intuitive User-interface
  • Simple navigation 
  • Customer support & Live-chat
  • One-click results.

Performance testing 

Lack of performance testing will lead to glitches, errors, and crashes like the examples mentioned before. Simulation of heavy loads of traffic helps in analyzing for its scalability, smoothness, and stability under various loads. Most applications crash due to the lack of performance testing. It includes,

  • Load testing 
  • Stress testing 
  • Spike testing 
  • Scalability testing
  • Volume testing.

Security testing 

BF is notorious for data thefts, hacks and security breaches and eCommerce applications are easy prey to cyber attackers. Login and Payment gateway are the most common victims, especially to Phishing. Security testing is essential as it not only keeps your site secure but also secures your database which holds sensitive details on customers. It usually includes,

  • Penetration testing
  • Risk assessment 
  • Vulnerability scanning and testing 
  • Security audit and testing

Database testing 

Most of the stores mentioned above failed due to the lack of sophisticated data. It is proven that cloud-based storage is far superior to a self-hosted database system. Testing the capacity of the database and its backup ability will prevent the application from downtime which would greatly impact sales. 

Compatibility testing 

Customers can access e-commerce applications on multiple devices across different operating systems and using various networks. It is necessary to ensure the application is compatible with the newest software updates, screen size, localization, and network adaptability. Only then an e-com app will be ready to use for the customers and help the stores to increase sales.
