Testing the sad path means asserting the app pushed back, not just that nothing crashed.
The test signs in with the wrong password. Add the assertion that proves the app shows the error message.
Nimbus login: demo@nimbus.app / secure123 is valid. The test uses a wrong password on purpose.
Fill in the missing assertion
The test is set up but proves nothing yet. Add the assertion where the TODO is.
We break each one in a copy of the app. Your assertion has to fail on every copy.
