The value of FE unit testing is inversely proportional to the amount of mocking in said tests. I once worked on a complex admin dashboard with lots of business edge cases. The unit tests for the forms and the settings didn’t have any mocks and therefore we could catch legitimate bugs. On the other hand I have worked on code bases with so much mocking that I couldn’t make the tests to fail by intentionally bricking the component.
