What is the step to take in TDD after the tests have failed?
A . Meet with the team to see why it fails
B. Change the test in a way that is passes
C. Run it again to verify it fails.
D. Write the code to satisfy the test

Answer: D

Explanation:

In TDD you start with writing the test before the code. This test cannot pass. If it does, the test is wrong. When the tests are written, the production code to satisfy the test will be written. Once all the tests succeeds, the product code is done.
