In today’s digital era, e-commerce websites have become an integral part of the retail industry. With the increasing number of online shoppers, it has become crucial for businesses to ensure that their e-commerce platforms are functioning seamlessly. 

One of the key aspects of ensuring the quality and reliability of an e-commerce website is thorough testing. 

In this article, we will explore the importance of testing e-commerce websites, provide a step-by-step guide on how to test them, discuss various test cases, and delve into the process of automating test cases for e-commerce websites.

Why Test E-commerce Websites?

By thoroughly testing an e-commerce website, businesses can enhance customer satisfaction, build trust, and increase conversion rates. Moreover, testing enables businesses to validate the functionality, usability, security, and performance of their platforms.

How to Test an E-commerce Website?

Testing an e-commerce website involves a systematic approach to cover all essential aspects. Here are the general steps to follow:

1. Identify Test Scenarios: Begin by understanding the different user actions and interactions that can occur on the website. This includes scenarios like user registration, product search, adding items to the cart, payment processing, and order placement.

2. Define Test Cases: Once the test scenarios are identified, create specific test cases for each scenario. Test cases should include inputs, expected outputs, and any preconditions or dependencies.

3. Prioritize Test Cases: Prioritize the test cases based on the criticality of the functionality being tested, user impact, and business requirements.

4. Execute Test Cases: Execute the defined test cases on the e-commerce website, following the test scripts and documenting the results.

5. Log and Track Defects: If any defects are found during the testing process, log them in a defect tracking system and track their resolution until they are fixed.

6. Retest Fixed Defects: After the identified defects are resolved, retest the affected areas to ensure the fixes are effective and have not introduced any new issues.

When to Automate Your E-commerce Website Test Cases?

Automating test cases for an e-commerce website can significantly increase efficiency and speed up the testing process. Automation is recommended in the following scenarios:

High frequency of test execution: When there are test cases that need to be executed frequently, automating them can help save time and effort.

Complex workflows: If the e-commerce website has intricate workflows that involve multiple steps, automation can ensure accurate execution and reduce the chances of human error.

Performance and load testing: Automating performance and load testing allows simulating heavy user traffic and identifying potential bottlenecks.

How to Automate Your E-commerce Website Test Cases:

To automate test cases for an e-commerce website, consider the following steps:

1. Choose a Test Automation Framework: Select a suitable test automation framework that aligns with your project requirements and supports the technologies used in your e-commerce website.

2. Identify Test Cases for Automation: Prioritize test cases that are stable, repetitive, time-consuming to execute manually, and critical for the website’s functionality.

3. Select an Automation Tool: There are several automation tools available in the market, such as Testsigma, Selenium, Appium or TestComplete. Choose a tool that best fits your requirements and offers a user-friendly interface.

4. Develop Test Scripts: Write test scripts using the chosen automation tool, considering the test cases identified for automation. Ensure the test scripts cover various scenarios and validate the essential functionalities of the e-commerce website.

5. Execute and Maintain Test Scripts: Execute the automated test scripts on a regular basis and maintain them by updating them as the website evolves. Regularly review and enhance the test scripts to improve test coverage and accuracy.

Below is an example of how test cases for an ecommerce website can be automated with a no-code test automation tool, Testsigma.

1. Navigate to the homepage of the e-commerce website: This step involves opening the e-commerce website in a browser. In Testsigma, you can use a simple command like “Go to URL ‘https://www.yourwebsite.com'”.

2. Search for a specific product: This step involves entering the product name into the search bar and submitting the search. In Testsigma, you can use commands like “Type ‘Product Name’ into ‘Search Bar'” and “Click on ‘Search Button'”.

3. Click on the product to go to the product details page: This step involves selecting the product from the search results to view its details. In Testsigma, you can use a command like “Click on ‘Product Link'”.

4. Click on the “Add to Cart” button: This step involves adding the product to the shopping cart. In Testsigma, you can use a command like “Click on ‘Add to Cart Button'”.

In each of these steps, ‘Search Bar’, ‘Search Button’, ‘Product Link’, and ‘Add to Cart Button’ are placeholders for the actual identifiers of these elements on your website. You’ll need to replace them with the actual identifiers, which can be the name, ID, CSS selector, XPath, etc., depending on what’s available and reliable for your website.

Also, Testsigma allows the use of variables and data-driven testing. For example, you can store the product name in a variable and use it in the test steps. This allows you to easily change the product you’re testing without modifying the test steps.

Remember to save your test case after defining all the steps. You can then run this test case to verify the “Add to Cart” functionality of your e-commerce website.

By following these steps, you can effectively automate your e-commerce website test cases using the Testsigma automation tool.
