What Happens When Access Is Denied? | (Permissions, Error Cases, 404s, Dropped Networks)

Good tests don't just check the happy path. This video goes looking for trouble: what happens when a Viewer tries to delete a task they shouldn't be able to, when someone navigates to a project that no longer exists, when the network drops mid-action, and when two people edit the same project at once. We test permission checks directly against the API — not just the UI — to prove the block is actually enforced server-side. Testing Taskmaster wraps up next with Video 20: wiring all of this into CI. #playwright #softwaretesting #edgecases #permissions #webdev #apitesting #testing #coding
