Testing techniques to test an e-commerce website

Welcome to the Manual Testing Free Training series.

In the last tutorial, we talked about the why and how to test an e-commerce site. Please refer to the following link to learn about e-commerce testing:


All right. As we discussed in the last tutorial, we split up the e-commerce testing into 2 parts. First one we already talked about, and the other one we are going to discuss in this tutorial.


So, we need to perform the following testing techniques to validate and verify the e-commerce site:


1. Functionality Testing Here are some of the checks that are performed, but not limited to the below list:

  • Verify there is no page found an error or invalid redirects.
  • Validate all required input fields.
  • Wrong inputs to perform negative testing.
  • Verify the workflow of the system.
  • Verify the data integrity.

Important note: we like to tell you that free tutorials are helpful to get started but if you are interested in the best online LIVE Master of Manual Testing training program from the experts, please refer to the following link:

2. Usability testing – To verify how the application is simple to use. Here is the checklist for Usability testing.

  • Check the navigation and controls.
  • Content checking.
  • Check for user intuition.

3. Interface testing – Performed to verify the interface and the data flow from one system to the other.

4. Compatibility testing — Compatibility testing is performed based on the context of the application.

  • Browser compatibility
  • Operating system compatibility
  • Compatible with various devices like iPad, smartphones, tablets, etc.

5. Performance testing – It is performed to assert the server response time and throughput under various load conditions.

  • Load testing – It is conducted to understand the behavior of the system under a specified load. Load testing will result in determining important business-critical transactions and load on the database, application server, etc. are also monitored.
  • Stress testing – It is performed to find the upper limit capacity of the system and also to determine how the system performs if the current load goes well above the expected maximum.
  • Soak testing – Soak Testing also known as endurance testing, is performed to determine the system parameters under the continuous expected load. During soak tests, the parameters such as memory utilization are observed to detect memory leaks or other performance issues. The main aim is to detect the system’s performance under sustained use.
  • Spike testing – Spike testing is conducted by increasing the number of users suddenly by a large amount and measuring the performance of the system. The main aim is to determine whether the system will be able to bear the workload.

6. Security testing – It is performed to verify the application’s security on the web, as data theft and unauthorized access are more common issues. So, here are some of the techniques to verify the system’s security level.

  • Injection
  • Broken Authentication and Session Management
  • Cross-Site Scripting (XSS)
  • Insecure Direct Object References
  • Security misconfiguration
  • Sensitive Data Exposure
  • Missing Function Level Access Control
  • Cross-Site Request Forgery (CSRF)
  • Using Components with Known Vulnerabilities
  • Invalidated Redirects and Forwards.


There can be many other techniques to do e-commerce testing. We have tried to cover overall techniques. Maybe Some people have more techniques for e-commerce testing. We recommend you keep exploring more techniques to do e-commerce testing.

In the next tutorial, we will talk about the Test plan document:
