Compatibility across browsers

Different users access a web application using different browsers. Cross-platform testing ensures the website is compatible with various web browsers and functions effectively on all platforms.

Improves website performance

Web application testing also checks a website’s speed and loading time. Users do not want web apps that load slowly. In fact, if a website takes more than 3 seconds to load, people leave that web application. Web app testing helps fix delayed load times and deliver a fast performing website.

Secures App from vulnerabilities

Web application testing ensures that the web applications are highly secure and free of data leakages. Any loophole in the security will increase the risks of potential cyberattacks on the web app.

Ensures high quality

Web application testing evaluates a website’s overall functionality, performance, compatibility, and security. Thus, it helps to enhance its quality matching the industry standards and customer expectations.

Saves Cost

The automated Web application Testing tools make it easier to identify errors and help reduce their occurrence repetitively. Thus, enterprises can save costs on repetitive tasks and bug fixing.

What Are The Steps For Conducting Web Application Testing?

steps for web app testing

Step 1: Functionality Testing

The first step in website testing is testing the application for its functionality. It includes checking the website for links, database connection, cookies, forms, etc.

Website functional testing should be performed in the early developing stages to identify and fix the issues quickly. Early detection of errors helps fix them in less time and cost. It also speeds up the whole app development lifecycle.

The functionality testing is performed several times during the development lifecycle. The results of the test are compared with the expected output. If it shows the same level of accuracy every time, the app is functionally correct.

Step 2: Usability Testing

The next step is to test the web application for usability. It combines functionality testing with the overall user experience.

The mobile usability testing is either done by external testers or internally by the developers themselves. Businesses can find suitable testers for external testing on apps like Apple’s TestFlight.

Usability testing is categorized into 4 stages:

Step 3: Interface Testing

The next step is to test the interactions between the app and web servers. It covers testing the communication process and the displaying of error messages. Also, it checks whether the server and user interruptions are handled properly.

Step 4: Compatibility Testing

Compatibility testing ensures your web application runs smoothly across all devices and platforms. It also covers checking the mobile browser compatibility, where the app should offer the same user experience as on the web.

Different operating systems display certain app elements differently on various browsers. Thus, running the compatibility tests with as many operating systems as possible is important. The most popular operating systems include Windows, Mac, Linux, etc., while popular browsers include Chrome, Internet Explorer, Safari, Firefox, etc.

Step 5: Performance Testing

The next step is to check the performance of your application in different situations. Performance testing includes testing the speed of the web application under different internet speeds- normal and peak loads.

Your website speed affects your public website’s SEO and overall user experience. So, testing your overall web server performance through a website speed automated test is good.

Step 6: Stress testing

Stress testing means determining the breaking point of the app. Under this test, the app is tested under different amounts of stress until it reaches the breaking point and stops functioning. If you know your app’s breaking point, you can fix it.

In case you need professional support, you can hire Mobile App Developers from Echoinnovate IT. We perform manual tests and use automation testing tools to evaluate web apps. The test aims to determine how to recover the app from crashes. The recovery should be smooth.

Step 7: Security Testing

The next step is to test your web application solution for security. This step identifies all the weak points, security patches, or leakages for quick fixes. After identifying and listing all potential threats and vulnerabilities, the security patches are fixed, and the apps are tested again.
