This can take many different forms, but its main purpose is to test a site or software with a diverse  group of potential users to ensure  it achieves the desired and planned objectives. Is it appealing to the people you’re trying to reach?  We’ll test it to be sure.  Usability testing is most often done through task-based questions, with the user sitting in front of a computer interacting with the site. How different groups use the site will be quickly apparent.  But more important, even if they navigate the site in different ways, does the site deliver the results we’re looking for?  The testing will give us the answer.
