Important Segments Of E-commerce Testing Web and Mobile Application

Every testing process contains small processes and segments within them. The completion of all of these segments altogether will make the testing process complete.

QA Specialists performing testing in an e-commerce system should plan well and lay down an integrated plan which should cover every aspect of e-commerce. Some of these aspects are mentioned below:



Homepage is the first page to appear when a user opens the website. On an e-commerce website, the homepage consists of a very rich and useful source of information, it will also link the user to different pages contained on the website for further use.

It is very crucial to test the interoperability and functionality of the homepage of the e-commerce website. You should also verify all the details and visual elements on the page. 

Category Pages

It is also one of the major areas in terms of testing. The range and breadth of the products should be tested by checking that the products are grouped under a similar category or not. 

QA Specialist should also check how quickly the user is able find the correct product category on the website for them. Split testing can also be used  to test the category pages for an e-commerce website.  

Product Detail Pages 
product details


The page containing the details of a product namely the product detail page is the heart of the e-commerce system. This is a very important factor in the way of success. 

Hence it is really important to make sure that the product details pages are tested thoroughly, and how the functionality of these pages work. The appearance of these pages should also be tested, this involves checking elements; 

  • the product code and title, 
  • product images, product description, 
  • enlarging the image, 
  • displaying related products, 
  • adding a product to a shopping cart, 
  • full body view of the product 

and many more. 

Shopping Cart 
Shopping Cart


Separate resources and efforts should be dedicated towards the functionality of the shopping cart. They should also test that the quantities, shopping cart items and display option are shown according to whether the transactions taking place on the website or not. 

The buying process should be the same throughout the store, therefore, it should be tested with the same regards. 

The functionality of removing and changing items in a shopping cart should also be tested and the effect of this activity in the final transactions should also work properly. 

Checkout and Payment Gateway


This factor is very important for both the businesses and the customers because it involves money. QA Specialists need to make sure that the completion of the payment should be smooth and secure. 

The checkout and payment gateway should also be tested with different payment options such as PayPal, cash, online banking, etc. 

Testing and making sure that the process of refunding and sending an email to a buyer is working properly should also be considered in the testing process of an e-commerce website. 


Cookies are used by the website to store information and data so that the memory of the web browser can be recalled for preferences whenever a user returns or revisits the same page. This feature exists to make the experience smooth and user-friendly. 

QA Specialists need to test whether the cookies used by the site are provided to the user as per the content stored. QA Specialists should also test the security settings, domain, and expiry date to make sure that the data is transferred between the browser and the server properly. 

User Accounts and Registration 
User Accounts and Registration


E-commerce and many other websites have the feature of creating an account on the website for personal use. Therefore, testing is obviously required in this aspect as user registration is the first step taken by the user before using the site. 

QA Specialists should test the registration process. This will verify that every user has a unique password and ID which is encrypted and stored in the system. 

It also includes various features such as validating the user's account and some related information, such as the shipping address, transaction history, and the stored information; this is to make sure that the customers should never have any trouble while using the website. 

Related and Recommended Products 

Related and Recommended Product


This is a marketing factor for businesses. This feature shows the product which is related to the product of interest to the customer. This feature is mainly incorporated to attract customers to shop more and more by showing them the products they may also be interested with. 

Clearly, this is a good business factor in a website. Various parts of this segment are also tested so that customers can buy more products. 

The main thing to test here is whether the algorithm showing these related products is working properly or not, which means that suggested products are relevant. 




This is also a crucial segment which should be tested thoroughly because most of the customers come to the website and search for a specific product that they have in mind. Hence the website should provide the result that the customer is expecting. 

This feature is also an important factor in determining the success of the e-commerce website because customers often have only a few features of a certain product in mind. Search algorithm of that website can help them find the best product.

For the search which has multi-page results, the navigation option should be available and it should be working properly. Many other tests concerning the results after the search and the accuracy of the search algorithm of the e-commerce website should be also carried out.

After-Order Tests 

Whenever a customer places an order there are many things that will happen afterward, such as it showing the shipping status of the product, there is an option to cancel the order in case the customer doesn’t want it or if they want to change their order - there is a feature for that too. 

Sometimes the customer wants to return their product in case of a defect or a complaint so there should be a feature relating to the returns as well. The things to be tested here are that these features are working properly and, most importantly, whether these features are easy to use or not because this can affect the customer. 

Browser Compatibility 

Different users use different browsers, therefore it is necessary for the website to work on every platform and browser. Browser compatibility is a very crucial aspect in the testing process for an e-commerce website. 

Therefore, the e-commerce website should be thoroughly tested on major browsers and their versions to make sure that the website has a wide reach and no potential customer should be left out due to the incompatibility of the website with a certain browser.

Testing E-commerce Application Workflow

The overall workflow of an e-commerce website testing consists of: 

  • Search functionality, Signup, and Login options. 
  • Feature for posting product reviews so that other customers can see them and make their decision.

Manual vs. Automated Testing of E commerce Site

Testing incorporates both manual testing techniques as well as automated testing techniques.

Both techniques ensure a very high quality of testing.; With automation testing, some of the problems can remain unseen. There are certain drawbacks to manual testing too.

Manual testing requires a lot of labor, effort, and resources and the process of manual testing is also very time-consuming. Since it is performed by a human it is also liable to have mistakes.

On the other hand, testing using automation tools has very few drawbacks and the advantages are numerous. It is faster and it shows better & quantifiable results as compared to the process of manual testing.

It makes sure that the incorporation of the transaction happening on an e-commerce website is taking place in a good and effective way, without creating any customer simulations.

Most Common Ecommerce Bugs

Despite being somewhat different on the outside, under the hood, your eCommerce website is a normal web application, just like every other. Because of this, it’s prone to have bugs. Here are some of the most common defects you can encounter in different areas. Focus on these areas during eCommerce testing.

Problems Finding Items

Most of the time when users visit your ecommerce site they know exactly what to look for. The easiest way to find those items is by using the Search option. What can happen there includes:

  • Search option returning no results despite the proper query
  • Search option not responding to click
  • Search option finding results different from expected (e.g. not associated with the search)

Problems Adding Items To Cart

User experience and purchase begin with finding a product and adding it to your cart. Only then can you begin the checkout process. But this functionality may sometimes not work properly. Some of the causes include:

  • “Add to cart” button not responding to click,
  • “Add to cart” button responding to click, but the product will not be added to cart (despite being shown as “Added” on the website),
  • “Add to cart” button responding to click and adding item, but immediately removing it.

These bugs may be a result of various things. Mistyped code on the frontend, problems with communication between your eCommerce site and its server, missing code on either side - there can be a variety of reasons.

Problems Removing Items From Cart

Obviously, it’s just as important to see if users can remove items from cart too, should they change their mind. What can happen here is pretty much mirroring the effects of adding items to cart:

  • “Remove from cart” button not responding to click,
  • “Remove from cart” button responding to click, but the product will not be removed from the cart (despite not being present e.g. until the user refreshes the cart),
  • “Remove from cart” button responding to click and removing an item, but immediately adding it again.

As said before - these bugs are very similar, because so is the behavior of this functionality.

Checkout And Payment Problems

Probably the most important step during checkout - if you want to earn some money, you want users to be able to pay (conversion rate) for the products. What you have to pay special attention to conducting eCommerce testing is:

  • User data is not transferred properly to the summary screen (either when a user is buying as a guest or has been registered before),
  • Delivery options are not available (if delivery is necessary)
  • No payment methods are available,
  • Certain payment methods malfunctioning (e.g. problems with communication between your eCommerce website and PayPal).

Obviously, your users should be able to complete the process from start to finish. If any bug stops them here, they won’t give you a second chance.

As simple as these cases may be on the outside, they take a huge toll on your eCommerce site. No customer wants to fight with bugs, everyone expects your app to work flawlessly.
