When practicing Test-Driven Development (TDD) with JUnit, what should you do if a test fails?Ignore the failure and continue writing more tests.Comment out the failed test until the code implementation is complete.Fix the code to make the test pass.Rerun all the tests to ensure the system's integrity.

The correct answer is: Fix the code to make the test pass.

Here are the steps you should follow when a test fails in Test-Driven Development (TDD) with JUnit:

1. Understand the Failure: The first step is to understand why the test failed. Look at the error message and the stack trace to understand what went wrong.

2. Debug the Code: If the error message and stack trace are not enough to understand the problem, you may need to debug the code. This could involve adding print statements, using a debugger, or manually tracing through the code.

3. Fix the Code: Once you understand the problem, you should fix the code to make the test pass. This could involve fixing a bug, adding a missing feature, or changing the code to handle a new edge case.

4. Rerun the Test: After fixing the code, you should rerun the test to make sure it now passes.

5. Rerun All Tests: Finally, you should rerun all the tests to ensure the system's integrity. This
