Quality Assurance and Testing

Quality checking is a proactive activity to check on a website’s “Health”

Quality Assurance

In Website development, Quality Assurance is based on Design testing, Requirement testing, and Functionality testing.


As a Website will be viewed across different Browsers and Mobile devices it is essential to test consistency and quality of design in a different layout. The basic functions of any website are plug-ins, links, and search. So make sure all these functions work well.


Validation testing will help us to understand whether we are building the product as per the requirement

Validation testing includes:

  • Checking whether the display and style components are contained within CSS
  • Checking all types of links (internal, external, mail and broken)
  • Having a look at the internal hyperlinks; they should be relative.
  • Checking to see if links aren’t leading to the same pages
  • Checking each page of the website. Each must have a valid XHTML markup. If there are any errors, you should correct them.
  • Making sure website doesn’t include dead-end web pages.

Tools that can be used in Validation testing:

  • Webpage analyzer (a tool that tests general website performance)
  • CSS Validator (a tool that checks HTML documents and Cascading Style Sheets)
  • XML checker and Validator (a tool that can determine the format and validity of an XML document)
  • Robots checker (a tool that can check the syntax of the robots.txt file)


  • All images should have the appropriate resolution.
  • Check whether the audio content works well.
  • Have a look at the color choices to have a pleasing design
  • Check whether you have provided all the alternatives to visual and auditory content (all images have meaningful ‘alt’ tags and comprehensive descriptions).
  • Check natural language use. Simply put, all abbreviations should always be expanded.
  • Check for captions. You need to make sure every caption is descriptive and available.
  • Access your website with the help of your keyboard (without the mouse).
  • Disable the style and you’ll see whether the content is lined up properly.
  • Zoom out of the images to see whether they are readable or not.


  • Taking a look at all fields once again and checking whether they are behaving properly.
  • Checking the alphanumeric fields: they should handle empty data, invalid characters, and negatives correctly.
  • Making sure that inputs that are too long are handled properly.
  • Should also check whether there are any automated script logins when you enter the CAPTCHA.

Quality Assurance and testing is a compulsory process in any development cycle of a product. It is essential to track all the bugs at every stage so that it is known to the developers and solved immediately to ensure the proper functioning of the website.
