Guide on Web Application Testing: Steps & Types

What is Web Application Testing?

Web app testing is the web-based application testing to ensure it works correctly, securely, and efficiently across different browsers, devices, and user scenarios. Testing web apps is essential for the website, verifying everything is in working order before releasing it to the public.

Importance of Web Application Testing

Web application testing is the quality control process for a web application. Without proper web application test, web applications can have data breaches, a bad user experience, and improper functioning. Web Testing in software testing is mandatory, but it is more appropriate with the right tools. 

• Early Detection of Bugs – One of the most important reasons to test a web application is to detect bugs very early. A bug found and fixed early in the SDLC is 30 times cheaper to fix than one found later in development, which is too big a figure to simply ignore. When bugs are detected early, fixes can be made immediately, and they won’t break the system.
• Check for Responsiveness – Checks if the web application looks the same across different devices of different sizes, layouts, and renderings. This is to ensure the visual correctness of your web application across devices.  
• Ensures Cross-Platform Compatibility – Is checking only visual correctness enough for your web application to work correctly? No, having just a nicely designed web application doesn’t mean a web application is good. Cross-platform compatibility ensures that web testing application work fine across different platforms.
• Prevent Cross-Site Scripting – Cross-Site Scripting (XSS) is a security vulnerability where attackers inject malicious scripts into web pages viewed by others. These scripts can steal cookies, session tokens, or redirect users. If these are left unchecked, users’ sensitive information can be hacked.
• Better Quality of Websites – Web application testing improves the quality of websites, offering better stability, performance, and functionality. 
• Secures from SQL Injection – SQL injection is a serious security threat where attackers penetrate into a website’s database by injecting SQL codes.

Different Types of Web Application Testing

Testing for web applications is a long process that involves different web application testing methods and techniques. 

Functional Testing

While evaluating a website’s functionality, the most important factors to consider are that all links, buttons, and forms operate as intended and that the navigation is sensible and straightforward. When adding a new form to a website, it’s critical to verify that it works correctly and adequately records data. So, 

• Verify that all links and buttons function correctly.
• Validation and submission of test forms
• Check that your website is responsive and operates on various devices and browsers.
• Ensure that your website’s navigation is simple.

Usability Testing

Usability testing is essential for ensuring a website is easy to use and intuitive. While testing, it should consider layout, typography, color scheme, and usability. When revamping a website’s homepage, make sure the new design is visually beautiful, user-friendly, and easy to navigate.

Here are a few things to think about.

• Text and image readability and legibility should be tested.
• Make sure your website is simple to use and comprehend.
• Examine your website’s general layout and style.
• Assess for design and user experience consistency across several pages.

Interface Testing

When creating a website, it’s critical to verify that the interface between the website and the database works correctly and that the website can handle a large amount of traffic without slowing down or crashing. Interface testing evaluates the interface between various website components, such as APIs, servers, and databases. Here are a few things to think about while testing your website’s interface:

• API functionality and compatibility should be tested.
• Check that the server and database connections are operational.
• Verify for data consistency throughout your website’s many components, and test for scalability and performance under varying loads and traffic levels.

Database Testing

When interacting with a database, it is critical to verify that client data is correctly saved and retrieved. Keep the following points in mind:

• Check the consistency and correctness of the data.
• Ensure that all data is being stored and retrieved accurately.
• Check if your database can manage large amounts of data.
• Scalability and performance should be tested under various loads and traffic levels.
