6 Strategies and Tools for Testing Your Web Applications

Testing web applications is crucial for a smooth and dependable user experience. It is an integral part of the development process, allowing web designers to ensure the quality and functionality of their applications. By conducting comprehensive testing, designers can confirm that the web applications meet performance, usability, and security standards on various devices and platforms. And, with the use of effective strategies and tools, designers can easily identify and resolve any issues before releasing their applications to users.

  1. Functional Testing

Functional testing is essential for web applications to ensure they are functioning correctly. This type of testing includes checking various aspects like user interface, APIs, servers, databases, and basic functionalities.

During functional testing, all the requirements are checked and understood, and test inputs are identified based on these requirements. Test cases are then executed, and the actual and expected outcomes are compared to ensure a positive user experience.

Some popular tools for functional testing include QTP, Selenium, and IBM Rational.

  1. Usability Testing

Discovering how user-friendly a web application is can be achieved through usability testing. This method involves testers who share similarities with the intended audience, evaluating the application’s navigation, interface, and overall user experience. By accessing the application in the same way as end-users, potential areas of improvement can be identified. 

Popular tools for conducting usability testing include Chalkmark, Contentsquare, and Clixpy.

  1. Interface Testing

Testing how a website communicates with different interfaces is crucial. This phase, known as interface testing, focuses on checking the application’s communication with application servers, database servers, and web servers.

For the application, this testing ensures that all test requests are correctly sent to the database and that the output is displayed accurately on the client end. Any errors are caught by the application and will be shown to the administrator rather than reaching the end-user.

The web server is responsible for handling all application requests without denying any of them. As for the database server, interface testing checks that all queries sent to the database yield the desired outcomes.

Common tools used for interface testing include Katalon, Selenium, and JMeter.

  1. Database Testing

Database testing is a crucial step in ensuring the consistency and integrity of your data. By executing queries and checking for errors, you can prevent data inconsistency and loss. Additionally, tracking the response time of queries helps optimize the performance of your web application. With database testing, you can also ensure data integrity and consistency, as well as check the load and scalability of your database. Whether you choose to do it manually or with the assistance of tools like QTP and Selenium, database testing is essential for maintaining a high-quality web application.

  1. Compatibility Testing

Ensuring consistency across various platforms, compatibility testing is essential due to the diverse range of devices, browsers, and operating systems. This testing is crucial because buttons, lists, images, and text fields undergo changes with each operating system. In addition, web applications can display differently depending on the browser and operating system being used. 

To tackle compatibility testing, the tool of choice is Dynatrace.

  1. Security Testing 

Security testing is a crucial process where the app is thoroughly tested in various security scenarios. It includes testing security levels using both manual and automated methods. The specific areas that are tested involve blocking unauthorized access to secure pages, restricting file downloads without proper approval, terminating automatic sessions after an extended period of user inactivity, and redirecting the website to encrypted SSL pages. 

To effectively uncover any hidden security threats, Intruder is a powerful tool that is widely utilized.

By adopting the right testing strategies and tools, our web developers in San Jose will enhance the functionality, compatibility, security, and performance of your web applications.
