What is Web Application QA Testing

More and more web applications are developed as of late . And with each line of code written, the potential for bugs arises. And the costs of fixing bugs increase exponentially the later you find them. This is where web application testing comes in. Let’s find out more on this below.

Web Application Testing – Definition

Website testing is checking your web application or website for potential bugs before its made live and is accessible to general public. Web Testing checks for functionality, usability, security, compatibility, performance of the web application or website. During this stage issues such as that of web application security, the functioning of the site, its access to handicapped as well as regular users and its ability to handle traffic is checked.

Web Application Testing – Steps

1. Functionality Testing 

It is a quality assurance process that bases its test cases on the specifications of the software component under test. It includes :

  • the identification of functions that software is supposed to do
  • data input and entry
  • verify the workflow of the system
  • verifying there is no dead page or invalid redirects

2. Usability testing 

Usability goes beyond functionality testing and combines testing for functionality as well as overall user experience. It basically tests to verify how the application is easy to use with. It tests the navigation and controls, content checking, checks for user intuition. 

3. Interface testing

Performed to verify the interface and the dataflow from one system to other. This includes checking the communication processes as well as making sure that error messages are displayed correctly.  

4. Compatibility testing   

  • Browser compatibility : Users typically view your website using a browser. Each browser interprets your website code in a slightly different manner. It may appear differently to visitors using different browsers. 
  • Operating system compatibility : Just like with different browsers, your web application might run into problems on some operating systems. Check that it runs smoothly on Windows, macOS, Linux, and Unix.

5. Performance testing

Performance testing entails using software tools to simulate how an application runs under specific circumstances. This includes load testing, stress testing, etc. Make sure you test the functionality under different scenarios and hardware configurations, and that your application recovers from crashes in the best way possible.

6. Security testing

Performed to verify if the application is secured on web as data theft and unauthorized access are more common issues. It helps in the following areas:

  • Secure Transmission
  • Authentication
  • Session Management
  • Authorization
  • Data Validation
  • Specific Functionality Tests
  • Error Handling
