How do you test for usability?

In a usability-testing session, a researcher (called a “facilitator” or a “moderator”) asks a participant to perform tasks, usually using one or more specific user interfaces. While the participant completes each task, the researcher observes the participant's behavior and listens for feedback.

What are the four 4 principles of usability testing?

1) Determine whether testers can complete tasks successfully and independently. 2) Assess their performance and mental state as they try to complete tasks, to see how well your design works. 3) See how much users enjoy using it. 4) Identify problems and their severity.
