Question
A manager is alarmed to see that all the tests for a new feature under development are failing. Why do all the unit tests in a Test-Driven Development (TDD) environment initially fail?
A. Because the code being tested has not been written yet.
B. Because the testing framework is configured last.
C. Because all tests will fail until they are linked to a definition of done.
D. Because in TDD, a failed test indicates the code works.
Answer
A. Because the code being tested has not been written yet.
Explanation
In TDD, tests are written first, all of which fail because no implementation code exists. Then, code is written to get the tests to pass. When all the tests pass, the feature is done.
