In usability testing basically I test the ease with which the user interfaces can be used. I ensure whether the application or the product built is user-friendly or not. I confirm that users feel comfortable with the application or Web site according to different parameters – the flow, navigation and layout, speed and content – especially in comparison to prior or similar applications. After the test I will verify the following things, — How easy is it for users to accomplish basic tasks the first time they encounter the design? Benefits of usability testing to the end user or the customer: — Better quality software Usability testing can help in discovering potential bugs and potholes in the system which generally are not visible to developers and even escape the other type of testing.
