For the most part, apps deliver a smooth user experience once developers release them to the public. However, a bug can bring the entire application down. When this happens, it is almost always because of the lack of application testing. Here are the six basic steps of the testing phase that software testing companies will use to assess a product.

Functionality Testing

The first thing to do is to ensure that the web application functions properly. Functionality testing studies the web page links, the database connection, cookies, and submission forms, among others. Developers must perform these tasks early in the app-building process. You can perform these automatically with software or manually through human testers. Multiple tests with different data should produce roughly the same accuracy before developers consider the app functionally correct.

Usability Testing

After functionality testing, developers perform usability testing. This kind combines the results of the functionality test and user experience. It involves developing a testing strategy that examines all app functions, including navigation and content, and recruiting test participants, both internal and external.

Interface Testing

After functionality and usability tests, interface testing comes next. This kind of test looks at the smoothness of interactions between the app servers and the web servers. Interface testing also looks at whether error messages display correctly and if the server properly handles interruptions (whether server- or user-side).

Compatibility Testing

Developers must also check browser compatibility and how the app displays information in different mobile browsers. The developers need to run the browser compatibility test to check if the app is displayed correctly in different browsers. Different operating systems show elements differently, so compatibility tests are vital in ensuring that the content stays the same when delivered to different users.

Performance Testing

After testing for compatibility, a developer must check performance under pressure. Testing under different internet speeds and loads is necessary. If possible, testing the overall web performance can also provide more information; a website speed automated test can help.

Performance testing helps software testing companies and developers identify the app’s “breaking point” and putting pressure on it in increasing amounts will identify the point at which the app will stop functioning. You need to know this ahead of consumers. Also, you should know how your app bounces back from a crash. If recovery isn’t smooth, you need to work on it.

Security Testing

Finally, a web application undergoes security testing, determining an app’s weak points through a series of fabricated attacks. To identify the app’s security needs, the developers or the testing team must gather all the pertinent information, including the developers’ operating system, hardware, technology, and the like. 

A tester would then identify and list potential vulnerabilities and threats, prepare a threat profile, and a test plan. Then, the developer will conduct both manual and automated security tests. Afterward, they will prepare security test case documents and fix any defects identified.


Testing is a vital part of website application development. However, some developers can underestimate it. This tendency is a problem because the older an application, the likelier it is for bugs to appear, and the costlier the repairs become. With proper website testing, developers can avoid bugs and ensure a successful rollout of the web application.
