A Six-Step Guide to Web Testing

Web applications are being developed with frequency these days, and each code line is liable to potential bugs. The cost of fixing these bugs is significantly more if they are found late, hence the need for web testing which allows developers to identify bugs very early and to test an application thoroughly before its release.

Web Testing varies procedure by procedure, and each of these procedures largely depend on your web testing requirements.

Here are the procedures for web testing

Functionality Testing

Before creating a web app, there must be some specifications that you expect from it as well as functional requirements.

This functional testing happens in the source code and its activities include:

  • Testing all links to ensure that none is broken. Outgoing, internal, anchor and Mailto links are to be checked;
  • Testing forms to guarantee that they are working according to expectations;
  • Testing cookies;
  • Testing HTML and CSS to make sure that search engines bring out your site easily;
  • Testing business workflow.

Usability Testing

This combines the functionality testing with more tests to guarantee the best user experience. This testing can be done within the development team or by getting external testers that are just like the potential user base of the web application.

Usability testing involve:

  • Testing the site navigation – Items such as the links to the site pages, links and menus should be visible;
  • Testing the content to determine that it is legible with zero errors. If there are images, they should contain an “alt test”.

Interface Testing

This web application testing certifies that all the interactions between the application server interface and the web server are smoothly run. The Application, Database Server, and the Web are tested, ensuring a smooth interface and correct display of error messages.

Compatibility Testing

This is a crucial aspect as it involves testing to check that your app is fully compatible with all browsers. The elements of this testing are:

  • Browser compatibility;
  • Operating system compatibility;
  • Mobile compatibility.

Performance Testing

It is also important to check that the functionality of your app is appropriate and responsive under heavy loads. It involves testing it to see its behaviour under regular and high loads and under various speeds internet. You should stress test the app by putting it under growing amounts of stress.

Security Testing

This final stage involves checking to verify that the application is protected against harmful actions (malicious software and viruses) and unauthorized access.
