What are Application Test Services and how do they work?

Web apps are being produced at an increasing rate these days. And with each line of code created, the possibility of problems increases. In general, the expenses of repairing problems rise exponentially the later they are discovered.

As per IBM’s Systems Sciences Institute, “the cost to correct a mistake detected after product release was four to five times greater than the cost to correct a mistake discovered during design, or up to five times higher.”

Research conducted by the University of Cambridge discovered that software vulnerabilities generate $312 billion in economic harm globally each year. These figures emphasise the necessity of detecting defects as soon as possible and fully testing a programme before it is deployed. Web application testing comes into play here. Web application testing often consists of many processes that guarantee an application is completely functional, works smoothly, and securely. It is an important element of web development since it guarantees that a programme runs correctly before it is released.

We created a 6-step approach that should give you an idea of what types of tests to conduct to test your app. Discover Qalified

Let’s get this party started!

Step 1: Perform Functional Testing

The first phase in web testing guarantees that a system’s functions are tested. Functional Testing is defined as follows on Wikipedia:

  • Functional testing is a sort of black-box testing and a quality assurance (QA) procedure that bases its test cases on the requirements of the software component under test. Internal programme structure is rarely considered when evaluating functions by feeding them input and reviewing the result (unlike white-box testing).
  • The usability testing includes testing for both functionality and overall user experience, in addition to functionality testing.
  • Typically, functional testing consists of the following steps: identifying the functions that software is expected to do; data input and entry; execution of the test case; and analysis of the actual findings.
  • Actual system utilisation is mimicked during functional testing. The goal is to simulate real-world system usage as closely as possible and to generate test circumstances that are relevant to user needs.

Step 2: Perform Usability Testing

The usability testing includes testing for both functionality and overall user experience, in addition to functionality testing. User acceptability testing  & Usability testing are not the same thing. Despite the fact that both are critical to the success of a web application. They each have a distinct focus and are carried out at various phases of the software development life cycle.

This may be conducted internally or by hiring external testers who are representative of your target audience. External testers can be found via services such as Apple’s TestFlight for apps built for the app store. Discover Qalified

The following steps are included in usability testing:

  • Create a testing plan to guarantee that all functions of your application are reviewed. Navigation and content are examples of this.
  • Recruit volunteers for the exam, either internally or outside.
  • Run the test in the presence of experts.
  • Analyze the results and make necessary improvements to your application.

Step 3: Perform Interface Testing

Interface testing guarantees that all interactions between the web server interface and the application server interface happen properly. This involves inspecting communication procedures and ensuring that error messages are shown accurately. Other things to check are that interrupts from both the user and the server are handled appropriately.

Step 4: Test for Compatibility

A critical stage in web application testing is ensuring that your programme is compatible with all browsers and devices. The following are the many components of compatibility testing:

Compatibility with browsers

Make certain that your application works properly across all browsers. This involves ensuring that JavaScript, AJAX, WebSockets, browser alerts, and authentication requests are functioning properly.

We propose LambdaTest, a cross-browser testing cloud, for browser compatibility testing. Users may use the Lambda tool to test their website on over 2000 genuine browsers and OS devices.

Aside from ensuring that your application works in all browsers (yes, even Internet Explorer! ), you should also test it in multiple browser versions to determine whether any upgrades influence its functioning.

Compatibility with various operating systems

Your web application, like other browsers, may encounter issues on certain operating systems. Check that it works well on Windows, macOS, Linux, and Unix systems.

Compatibility with mobile devices

Mobile compatibility is now a given. Web testing requires ensuring that your application works on multiple devices and operates just as effectively on Android as it does on iOS.

Step 5: Performance Evaluation

After checking that your application’s functionality works effectively and responsively across all browsers and devices, examine how it performs under severe demand. This includes testing the application at various internet speeds and seeing how it performs under typical and peak usage (load testing). To establish the breaking point of your application, it is subjected to escalating levels of stress until it no longer functions (stress testing).

Testing for robustness is an important activity because it allows you to discover how your application operates under stress before your users do. Make certain that you test the functionality in a variety of scenarios and hardware configurations, and that your programme recovers from crashes as effectively as feasible.

Step 6: Security Testing

The last stage of web application testing ensures that your programme is safe against unauthorised access and dangerous acts caused by viruses or other malicious malware.

The following actions are included in web application security testing:

  • Check to see if secure pages may be accessed without authentication.
  • Check that active sessions are closed after an extended period of inactivity by the user.
  • Check the application’s SSL certificate.
  • Ensure that prohibited files cannot be downloaded without permission.

Wrapping it up.

These are the six phases of testing a web application. If you properly follow these procedures before releasing your application, you should be able to detect any flaws and mistakes and solve them before it’s too late.
