#22 - Register product stock items - Part 3

After finding out about the problem with the UI integration tests in video #21, let's dig deeper into the problem and resolve the root cause of the flaky tests:

• see tests running in isolation, but not in the whole suite
• debug tests to find the problem of incorrect entity comparison
• find out that multiple screens are still open from other tests
• reason about the shared state of "opened screens"
• fix by clearing up all screens at the beginning of each test case
