Web App Testing Techniques Every Tester Should Know

Web app testing is a mandatory skill for Software test engineers these days. The progress in web technologies such as Java/J2EE, JavaScript, HTML5, PHP, AngularJS, Node.js, and React is the leading force driving the organizations to produce an increasing number of internet applications.

Not only the websites but also there are locally hosted enterprise-level applications that are utilizing web technologies. Web applications can easily be scalable, supports multiple browsers, and can run on many different devices. Furthermore, they are platform-independent, easy to use, no need to set up, not need admin rights, and lessens the cost of earnings.

Bundled with all these capacities, a Web Application had to pass a set of validations to ensure quality. Not just all of the UI flows demand testing but also ports like SOAP and REST APIs, which enable customization at the client end.

Thus, a tester may embrace some or all the web application testing methods mentioned in the area below. These are time-proven methods that are often used across the testing world and known for delivering outcomes.

Web Appl Testing Techniques

Functional Testing

It is among the most common testing methods to check if the item works as the customer intended for and fulfills the requirements listed in the developer’s documentation. It features the following tasks.

Testing UI Workflows

Every web program has many small business workflows a trainee may know from the requirement specification file. However, in the Agile version, there happen product dressing meetings to go over the functionality. Therefore, the tester here will write test cases to cover different situations and establish success criteria.

Usability Testing

Usability testing verifies the web application provides a pleasing user experience. Not only the testers but also the real users or the clients of the product perform usability testing. While the conventional testing carries out by a developer, designer, or project supervisor, usability testing avoids any bias by taking feedback from the end-user. There are usually three types of usability testing to conduct usability analysis.

Compatibility Testing

Compatibility testing confirms the site design is compatible across different browsers and also on many different devices. It features the following tests.

Performance Testing

Performance testing plans to trespass the boundaries of standard measurement and aims to check the application response time and throughput under different load conditions. Usually, we can group these tests into four categories.

Security Testing

Security testing is crucial for all types of internet applications. It makes sure the program will not allow unauthorized access to some of its tools that may break the site itself. And more importantly, it ensures that the sensitive info is secure and will not lead to any social or financial damage to its users. Here, we’re sharing some of the best security testing methods which a tester can apply to discover the safety issues.

SQL Injection

It is a technique that requires benefit from ambiguities within the web application and bypasses ambient security checks. To prevent such attacks, the kind shouldn’t allow exceptional characters or use them properly.

Unauthorized Data Access

It’s a technique that suggests getting unauthorized access to data inside an application. Such information flows occur on servers or launched via networks.

URL Manipulation

This approach modifies the site URL and steals essential information. It occurs when the application uses the HTTP GET method to exchange data between the client and the host. The data is passed in parameters in the query string. The tester can alter a parameter value in the query string to assess if the server takes it.

Vulnerability Scanning

Testers can utilize an automated computer program to identify security loopholes of the web software and determine where it can be exploited or compromised.

Summary

Being a web tester, you must notice that testing a web app testing requires appropriate essential steps to guarantee the quality of the item. However, there is always a continuing pressure on testers to discharge early.

Hopefully, the above tutorial would enable you to learn the intricacies involved and build you a much better plan for testing.
