eCommerce Application Testing: User Interface & Functional Testing – Part 1

Retail eCommerce sales worldwide are about to reach 6,542 billion USD by 2023. B2C eCommerce platforms have emerged as the most popular online channel in the past few years. Evolving technology, increasing customer aspirations and intensifying competition have made it essential for businesses to release flawless eCommerce applications.

Business leaders are constantly strategizing for more user-friendly and secure eCommerce applications. The rapid evolution of eCommerce business needs and technologies has enabled several businesses to integrate with online sales channels. Delivering seamless, homogeneous and qualitative user experience has become the topmost priority for businesses to stay ahead of the market. Today, users expect the same information and functionalities on every device including smartphones, tablets or desktops that they use interchangeably.

Hence, eCommerce businesses need to offer seamlessness in their online sales channels to ensure their platform is compatible with any kind of device that a potential customer might use for shopping. Online shopping websites are also intrinsically dynamic and are always buzzing with new products, offers and promotional schemes leading to constant change.

This is where the role of a test engineer steps in. Compatibility with every device needs to be tested to ensure all functions are available and uniform. Also, methodical eCommerce application testing is taken up to control and balance the unique UI and functional differences of each browser.

How Quality Impacts Business?

As they say – the first impression is the last impression. If a customer faces any sort of difficulty during the first visit then there are very high chances that the customer will abandon the website and never come back. This is why it is crucial to keep everything in the best possible shape to start with, to create a lasting impression.

eCommerce sites need to ensure that their user experiences are positive. A digital product’s quality has a tremendous impact on conversion rates, acquisition costs and overall, on business.

The majority of online shopping sites have similar basic wireframes to navigate.  These include the more common ones such as :

  • Homepage
  • Product Page
  • Search Result Page
  • Order Page
  • Order Confirmation Page
  • User Account Page
  • Login Page

Applications will definitely have more pages than these but these are some of the more common ones that are universal for the eCommerce domain. Above mentioned pages are crucial for any customer’s shopping journey, hence these pages need to be tested thoroughly to provide the best possible user experience.

Here are a few core points to remember while testing these pages.

Homepage

The homepage receives the maximum number of visitors, calling for through functional testing. This is also the most common landing page, making it important to have the best UI / UX experience. For instance, if there is an auto-scroll feature on the homepage then how often the images are loading, what is the load speed, can user hover over the image, are the images clickable and rendition of various browsers and devices should be checked.

Here are other features that need to be checked:

  1. Search

Search functionality is used on almost all the pages of an eCommerce website to help users look for specific products. While deploying such functionalities, it is a common practice that the same code of the search module is applied across other pages of the website. It could also be integrated into the header of the website. However, the behaviour of the search module needs to be uniform irrespective of the location where it is integrated.

  1. Loading Speed

The faster load is always an advantage for  any eCommerce website ahead of the market automatically. A sluggish website could result in loss of customers and impact on brand image. This has to be a number that is tested for in discussion with business teams and what is the current standard in the market/across competition.

Normal users select between 4 to 5 options to classify their search results. Test results should focus on search results after each and every parameter is applied to check whether they are correct or not.

eCommerce websites ask users to register and login to capture essential data including email, phone number, order history and address of the user. It is done to deliver a more user-friendly and customized service to the customers. However, there are a few websites that allow customers to make the purchase without creating an account.

Check out whether the account created has all the relevant information correctly including  address, card details, phone number of the customer.

  1. Login Redirection

  1. Clicking on the Product

When a user clicks on the product in the shopping cart then more information about the product should be displayed through a pop-up or by redirecting to the product page.

  1. Coupons

The correct amount of discount should be applied after the application of the coupon.

Users tend to collect all the products in the shopping cart and hold them for several days before buying them finally. In this duration a lot of stock fluctuation happens. ‘Out of Stock’ or ‘In Stock’ status should be displayed against the product.
