Top 6 Website QA Testing & Quality Assurance Checklist 2022


Dhruvil Pandya

Each one of you working in the software industry has been in a situation where a particular bug ruined your app’s user experience. Ever wondered why these things occur? The answer is straightforward: the lack of proper website QA testing. The website QA testing phase is a crucial aspect of app development through some developers tend to overlook it. The issue is that the chance of a bug appearing increases with every line of code and the time and resource cost of bug fixing increases with time. But, optimal website testing can help you mitigate these problems before they occur. Hence, if the application testing runs without any glitches, the app can be launched sooner than expected without major bugs.

If you follow the Agile methodology, it is critical to combine the web QA testing phase with the development phase efficiently. In this blog, we are going to discuss the unavoidable steps to be included in the Web Application Testing Checklist. But, first, let us understand what web testing is?

What is Web Application Testing?

Website QA testing is a software testing process to test websites or web applications to look for potential bugs. It is thorough testing of web-based applications before going live. Ideally, a web application needs to be thoroughly tested from end to end before it goes

live for end users. Web testing looks for functionality, usability, security, compatibility, the performance of the web application or website. By executing web application testing, a business can ensure that the web-based system is functioning well and will offer an optimum user experience for the end-users. The UI design and functionality are the main pillars of website QA testing.

What are the advantages of web application testing?

1. Browser Compatibility

The practice of web app testing assists the apps to be compatible with all web browsers. End-users use various types of browsers while surfing the web. The web app testing efficiently assists the apps to function the same for every user using different browsers.

2. Enhances Website Performance

The method of website QA testing helps to overcome the slow app performance. Apps with slow performance are not the choice for search engines or for the end users. Web application testing helps to recover the load time delays due to the graphics, code etc. and maintain a quality application.

3. Secures App from Issues

Security is one of the main concerns for every application or website. Every day we keep hearing about websites being hacked, hence there is an immediate need for every small and large enterprise to practice web app testing to make sure that the applications are free from various types of security issues.

4. High-Quality Application

The end-to-end user testing efficiently assists in improving the performance and functionality of the application. This type of testing helps to find and resolve the bugs at earliest. Hence, a high-quality application will be achieved before the release.

5. Saves Time and Money

The end-to-end web app testing through automation tools decreases the occurrence of mistakes and the performance of repetitive test cases. This will assist the enterprises to get quality results with reduced time and cost.

Web App Testing Checklist for App Quality Assurance -

If you wish to make the application right, you must go through these 6 steps of the testing process. We will now take a look at each of these steps in detail:

 - Functionality Testing

Now you know what a web application and web application testing are so let us get started. The first phase of testing is to ensure that the web application is functionally appropriate. Functionality testing is focused on the database connectivity, all links in the web pages, cookies, forms used to get user info etc. This should be done early in the development phase to speed up the entire app-building process and reduce risks towards the end of development.

It all comes down to a set of tasks that can be performed both automatically with the use of a software program or manually. Once the results are out, you just compare them with the expected output. You need to perform functionality testing multiple times with a set of different data. If the accuracy is the same every time, the app is functionally right. It is not possible to get rid of each and every bug, though frequent testing offers a better opportunity to develop apps that are as functional as possible.

 - Usability Testing

The second phase in web testing is usability testing. This kind of testing combines functionality testing along with user experience. However, it is not the same as User Acceptance testing since the focus is completely different and also the stages of app development. Usability testing can be performed by getting external testers that stimulate your expected user base, or by the developers themselves. If you are looking to perform external testing but don’t know where to start, you can start with the following 4 steps:

  • Develop the testing strategy in a way that all functions are examined including the navigation and content.
  • Recruit internal or external test participants
  • Run the test with a team of professionals
  • Analyze the results and improve your app accordingly.

 - Interface Testing

The Interface testing phase comes after successful completion of the functionality and usability testing. This testing phase looks for a smooth interaction between the app server and the webserver. Along with the communication process, the displaying of error messages needs to run too. Moreover, this test is used to determine whether the interruptions by the server or by the user are handled appropriately.

 - Compatibility Testing

Fourth on this list of web testing phases is compatibility testing. In this digital world, compatibility testing is more important than ever to make sure that your web application looks as good as it should on all types of devices. The developers need to run the browser compatibility test to check if the app is displayed correctly in multiple browsers. You can run another alternate test which is the browser compatibility test which confirms that the application is displayed appropriately across all the mobile browsers. Various operating systems display specific elements differently. Hence, it is critical to run the compatibility tests with different operating systems, especially the popular ones like Windows, Mac, Linux along with different browsers like Chrome, Internet Explorer, Safari, Firefox etc.

 - Performance Testing

Once the application is functional and responsive, you need to check if the performance is under a heavy load. Performance testing means testing under distinct internet speeds along with normal and peak loads. In a broader context, it might be a better idea to test your web server performance on a basic level, through a website speed automated test because page speed impacts user experience and also affects your website’s SEO. You can perform a basic speed test with the help of free tools and use that data to prepare an optimization plan.

It is not a proper in-depth performance and stress testing, but a good starting point. Stress testing is used to identify the breaking point of the app which includes putting the app under increasing amounts of stress until it stops functioning. You will need to identify your app’s breaking point before the users do. Bear in mind that you need to figure out how your application recovers from crashes. If the recovery is messy, you will have to work on its enhancement.

 - Security Testing

Once the web application is developed, it needs to be tested for security. This kind of testing has all types of processes to identify the application’s weaknesses and enhance them as much as possible. Generally, a number of fake malicious attacks are used to test how the application responds and performs under these testing times. If security issues are found, it is crucial that you find a possible solution to overcome them.

Some of the basic steps of security testing are:

  • Understand the security goals and plan the test by thinking about the security needs of each of them.
  • Determine the application’s security requirements.
  • Collect the information about the elements used to build the app like the operating system, hardware, technology stack and more.
  • Determine and list all possible threats and issues.
  • Make a threat profile based on the listed threats.
  • Make the test plan.
  • Automated testing along with manual testing.
  • Make the security tests case documentation
  • Perform Security test case execution, fix identified defects and retest
  • Prepare a comprehensive report on security testing with solved issues and possible threats.


In this article, we looked at the importance of this phase of app development along with the crucial steps you need to take to test your app efficiently. Regular web application testing reduces the chances of bugs spoiling the customer experience and it also provides a better overall idea about how your app performs, the strengths and the hidden weaknesses.
