There will be some scenarios where tester will not receive any requirement document or any supporting document to understand the product in that scenario tester will explore the application keeping the testing objective in mind and will try to find the bugs.
Usability Testing: In this testing tester will check that how ease is the use of application like navigation, proper placement of GUI elements, text color and background color combinations are readable and other things like this.
UX Testing: UX testing is checking the overall User experience. Such as how is your application, how is the application layout, how are your products displayed on web, how is the content. Usability testing is also one factor to ensure that the User Experience is high.
