- Before starting with web app testing, check a handy 58-point checklist. This includes functionality checks, user interface checks, performance checks, and security tests.
- Include a rigorous security testing protocol in your checklist. You should aim to cover 95% of potential security vulnerabilities, like SQL injection and XSS attacks. A secure application not only protects the user data but also the reputation of your business.
- Simulate high-traffic scenarios to verify the robustness of your application under stress. Performance testing can help ensure that your application can handle peak load times, thereby providing a consistent user experience regardless of the server load.
If you are looking to develop a secure web application, you need to ensure your web app solution is error-free.
Before your web application is deployed, web app testing is required to meet the user’s requirements. And, if you have a checklist handy, it even makes it easy to test the web application.
Being a leading web application development service provider, we understand how much important, it is to rigorously test the web application. So, here is a blog post that provides a comprehensive web application testing checklist, tailor-made for you to validate all the aspects of your web app. This guide just doesn’t talk about functionality testing, but also important factors like usability, compatibility, and security testing.
You can read through the checklist right here in this post. So, let’s get started with the different website testing types and its checklist.

What is Functional Testing?
Functional testing is a type of software testing that verifies that the software functions as expected. This is achieved by providing input to the system and then checking the output against the functional requirements or specifications. Functional website testing does not look at the internal workings of a system but focuses on the results of processing.
- All outgoing links are working correctly.
- All internal links are functional. Ensure there are no broken links.
- Anchor links are correctly directed to the intended section.
- MailTo links initiate an email request to the correct address.
- All forms function as expected.
- Error messages are displayed for invalid input.
- Mandatory fields are indicated, and forms cannot be submitted if these fields are empty.
- Consistent behaviors or actions occur on form submission.
- Cookies are set, function, and expire as expected.
- Session test data is correctly maintained between different web pages.
- Sessions expire correctly after a period of inactivity.
- The application successfully connects to the database.
- Data is correctly retrieved from the database.
- Changes to data are successfully updated in the database.
- Data storage functions correctly and without errors.

Usability tests are performed from the end user’s perspective and help to determine how user-friendly the system is. In this website testing, real users interact with the software to perform specific tasks while observers watch, listen, and take notes.
- Check if the content is easy to read and comprehend.
- Verify that all icons, images, and multimedia convey the correct message and are harmonious with the text.
- Ensure that navigation elements like menus, breadcrumbs, links, and buttons are intuitive and consistently placed.
- Check if feedback is provided when user actions are successful or unsuccessful (e.g., form submission).
- Verify that typography, color schemes, button styles, spacing, and imagery are consistent throughout the application.
- Check if the application’s design adheres to established best practices for the platform (e.g., web, mobile).
- Measure how quickly a new user can learn to use the system for the first time.
- Test the discoverability of features and options.
- Gather qualitative feedback about the user’s experience (e.g., what they liked or disliked, suggestions for improvements).
- Monitor users’ facial expressions, comments, and body language for indications of frustration or satisfaction.
