Test-Driven Development (TDD) FAQs

Question 1

When can I skip TDD while using this skill?

Accepted Answer

Exceptions are rare but typically include throwaway prototypes, purely generated code, or simple configuration files. In most professional contexts, it is best to ask a human partner before bypassing TDD practices.

Question 2

Why does this skill insist on writing the test before the code?

Accepted Answer

Writing the test first ensures that the test actually fails for the correct reason. If a test passes immediately, it proves nothing about your new code; by watching it fail, you verify that your test is accurately checking the intended behavior.

Question 3

Is TDD suitable for bug fixes?

Accepted Answer

Yes, TDD is the preferred method for fixing bugs. You start by writing a failing test that reproduces the reported bug, then implement the minimal fix required to make the test pass, ensuring the bug is gone and won't return.

Question 4

Does TDD slow down the development process?

Accepted Answer

While it may feel slower initially, TDD is faster over the long term because it significantly reduces time spent debugging and prevents regressions that would otherwise require emergency fixes later.

Question 5

What should I do if I accidentally wrote the code before the test?

Accepted Answer

The TDD 'Iron Law' suggests you should delete the implementation code and start over. This prevents the 'sunk cost' of keeping unverified code and ensures that your final implementation is strictly driven by the requirements of the test.
