Testing web applications is the process of checking yours or another person’s web application or website for potential threats and vulnerabilities before it’s made live on the web. 

The testing process is one of the most important aspects of app development however the majority of developers actually underestimate the value of performing it.

Through ego that their code is elite and superior? Who knows. 

What we do know is that when a bug does appear it could be costly to fix depending on the severity, however with the usage of proper website testing risks of bugs can be mitigated. A basic rule of thumb is if the application testing goes smoothly, the app is ready to go live. 

So what are the basics of performing a web application test? Well we’re going to show you.

Step 1: Testing the Functionality

One of the first steps that needs to be conducted is the testing of functionality. These types of tests consist of checking database connections, that all links on the web page work, that cookies and forms are used and getting the correct info and so on.

This should be done early in the dev stage in order to speed up the entire app building process, doing so reduces the risks that may arise near the end of the process.

Step 2: Usability Testing

Usability testing is best carried out using external testers in a real-life way that you would expect your user base to. Sometimes these are also performed internally by the development team.

Usability testing can be broken down to 4 stages. The development of the testing strategy in a way that all app features/functions are examined including the navigation and content. Through recruiting the internal or external test participants, running the test with the team of experts and finally analyzing results and improving your app accordingly.

Step 3: Interface Testing

This web page test determines whether or not the app server and web server’s interactions are smooth. Not only must the contact mechanism be checked, but so must the display of error messages. This test is often used to assess if server and/or user interruptions are treated properly.

Step 4: Compatibility Testing

The browser compatibility test must be performed by the developers to ensure that the software displays correctly in different browsers. Another test to perform is mobile device compatibility, which is intended to ensure that the software shows correctly across mobile devices. 

Certain app elements are displayed differently on various operating systems. This is why it is critical to run compatibility tests with as many operating systems as possible, especially the most common ones like Windows, Mac, and Linux, as well as with various popular browsers like Chrome, Internet Explorer, Safari, and Firefox.

Step 5: Performance Testing

If you’ve determined that your software is stable and sensitive, you can test its output under heavy load. Performance testing entails testing at various internet speeds as well as at regular and peak loads.

Stress testing is useful for determining the app’s breaking point; it includes subjecting the app to increasing levels of stress until it ceases working. After all, you need to find the breaking point of your app before the users do.

Step 6: Security Testing

If the web application has been developed, it must be checked for protection. This method of testing entails a variety of processes aimed at identifying the app’s weak points and improving them as much as possible.
