Testing Anti-Pattern Guard FAQs

Question 1

When should I use integration tests instead of mocks?

Accepted Answer

If your mock setup becomes longer than the test logic itself or if you are mocking everything in sight, it is a red flag that an integration test would be simpler and more effective.

Question 2

Why shouldn't I add test-only methods to production code?

Accepted Answer

Adding test-only methods pollutes the production API, increases the surface area for bugs, and creates confusion for other developers about which methods are safe to use in a live environment.

Question 3

How does this skill improve AI-generated tests?

Accepted Answer

It forces Claude to focus on verifying real behavior and prevents it from taking shortcuts like creating partial mocks that might hide downstream bugs.

Question 4

What are testing anti-patterns?

Accepted Answer

Testing anti-patterns are common but suboptimal testing habits, such as asserting on how a mock is called rather than the outcome of the code, or polluting production classes with methods used only in tests.

Question 5

Does this skill work with Test-Driven Development (TDD)?

Accepted Answer

Yes, it is designed to be complementary to TDD. While strict TDD prevents many anti-patterns naturally, this skill provides a safety net during refactoring and modification of existing tests.
