Question 109 · 530 in bank
Which task is performed because the test-driven development approach is being used?
Show answer
Answer: C
Explanation
I really struggle with this one because: A. creating test scenarios based on continuous development *technically - this is true because you write the tests, then prove they fail, then write code that passes the test. B. writing code without committing any coding violations This one is dumb and obviously not the right path. C. refactoring code that is covered by existing tests So according to the answer given in the main question, refactoring is what causes the old tests to fail because you make a change. D. testing existing software before developing new code Technically you're doing this all the time because you test each 'chunk' of code as you write it. I'm guessing that D is the 'most correct' but I can see how A,C, and D all would be correct.
