DIY Quality Assurance Checklist for Web Application Testing

Checklist For Website Testing
Quality assurance is as important to a website as the development to ensure that the website does not fail in any part of the functionality when it is given to the users.

A website that fails when users use it will cost a great deal to businesses and the worst part is that the users lose trust in it.

Why should we use a checklist for testing?

Without planning, you might tend to miss out some of the functionalities while assuring the quality of the site.

Preparing a checklist by oneself from the scratch is time-consuming and strenuous when you are a part of a large project.

It is highly required to have a checklist so that you can take a chill pill that no feature is missed out from testing and the quality is.


Web application development companies follow a detailed list of quality checklists that help them to ensure that the website does not have any loopholes when it is up and running.
