Test Case

You might say

Write a failed-login test case so another person can use the same account and steps and see the same result.

A test case is one repeatable check that states preparation, action, input, and expected result.Prepare a registered account, enter its email with a wrong password, submit, and expect an explanation without entering the account page. This lets people or automation check the same thing. “Test login” is a test plan, not one executable case.

Test Case

How a wrong password travels through one full test case

The same account, input, and action make this check repeatable.

What one case needs to retain

Give the same starting point and action: State the account condition, input, and clicks so another person can reproduce the situation. Automation also needs stable preparation, not data left from a prior run.

Compare expectation with reality: A case does not merely say “tested.” It records what should appear and what actually appeared, including a page, response, or failure information when useful.

You can say this to an AI Agent

Add a wrong-password login test case with preconditions, input, action, and expected result. After implementation, actually run it once and confirm it does not enter the account page and the error is clear.
