Testing from a UI perspective

The testing that we will do now is similar to the kind of tests that a person using the app could do. In fact, in companies that have QA (Quality Assurance), people use these tools as a complement to manual testing.

UI tests can be automated as well, but they differ from unit and integration tests; these are actions performed on the screen, from clicking on a button to completing a registration process with recorded events.
