Black Friday: How to test your web and mobile applications

To get ready for Black Friday and the start of the winter holiday shopping season, it is crucial for retailers to test their web and mobile applications. 

Black Friday's Impact on Sales

Black Friday and Cyber Monday (BFCM) are some of the busiest and most profitable days of the year for many retailers. What started as an American phenomenon is now spreading to other countries including Canada, UK, France, China, Spain, and more with consumers spending billions, online and in-store, purchasing a variety of goods.

Global Impact of Black Friday and Cyber Monday

 

A growing trend for Black Friday and Cyber Monday is the growth of e-commerce, especially m-commerce as more shoppers are using their smartphones to make purchases. In 2017, in the U.S. alone, Cyber Monday was the first mobile shopping day over $2 billion.

More importantly, mobiles were the most important driver of e-commerce traffic and sales during the 2019 holiday season. According to a Salesforce report, the 2019 season saw up to 80% of online traffic and 65% of online transactions come through a mobile device. 

Mobile e-commerce is up and poised for further growth

 

Given the economic reality,  it is vital for retailers to test their website and mobile apps to uncover and eliminate bugs and other anomalies that can reduce conversion rates, lead to a higher cart abandonment rate, crashes, and more. 

How to Test E-commerce Apps and Websites?

The key to an effective web or mobile app test is its ability to meet your particular needs. Here, the first step is to define the goals or objective of the test. This should reflect the particular nature of the site or app as well as the needs of the client. With a clear set of goals in mind, it is easier to design a test that is capable of meeting these goals.

E-commerce Test Cases

Testing Updates

It is common for sites and apps to receive an update in anticipation of Black Friday. New banners, pages, links, color schemes and other elements are often added to attract the attention of online shoppers and redirect them to particular items, information, or pages. When updates include the addition of new functionalities, it is important that they are tested. Failure to do this will make it harder to preserve the quality user experience that you have worked hard to provide. 

Load Testing

With higher traffic on Black Friday, it is essential to test your site’s and app’s ability to handle a higher level of traffic. Using your existing traffic data, you can establish a baseline for a load test to assess how much traffic can be handled before the platform’s performance declines and/or crashes. By executing load tests, retailers can improve the stability of web and mobile applications and avoid major problems on Black Friday and other peak shopping days of the season. 

Test Promo Codes and Discounts

Discounts and deals are the heart of Black Friday. Therefore, it is vital to test checkout page to make sure that the discounts and promo codes are properly administered. If not, you run the risk of allowing a bug to disrupt sales leading to frustrated users and lower revenue. 

Test the Shopping Cart 

The shopping journey (add to cart, checkout, email confirmation, …) must be reviewed several times to make sure it unperturbed. It would be extremely unfortunate if an “Add to cart” button does not work preventing customers from placing an order online. Overall, tests cases should focus on every aspect of the cart from adding items to the display of error messages when problems do occur. 

Regression Testing

Regression testing will verify that updates to your site or app do not result in unintended bugs in other parts of your site or app. This type of testing can executed manually or an automated testing script. In either case, it is important to make sure that new updates or iterations to a site or app do not result in new bugs or anomalies that will annoy your shoppers. 

Multidevice Testing

Today, more and more people are shopping online using their mobile devices. As a result, it is crucial to execute multidevice testing on websites and apps across a variety of mobile devices, operating systems, and different browsers. Having a large test coverage is key to uncovering any bugs or problems that cab be traced to the fragmentation of the smartphone market. Multidevice testing is the best way to ensure that your site or app appears and performs as expected for the greatest number of shoppers. 

Test Bug Fixes

At the end a test campaign, your development team will be busy with bug fixes which will undoubtedly improve your site or app. Nonetheless, it is beneficial to verify the bug fixes. This can be done by retesting the affected elements or by retesting the entire site to ensure the proper corrections have been made.


History repeats itself so it's safe to say that some sites and apps will crash as a result of Black Friday. Nonetheless, this will cost these business dearly. Avoid this fate by testing your site and app to uncover areas of concerns and bugs that can hinder your economic performance.
