Test Architecture Patterns FAQs

Question 1

Does this skill support testing private functions?

Accepted Answer

No, it follows the best practice of testing only public interfaces. If a private function requires direct testing, the skill suggests it should either be implicit in public tests or be refactored into a public interface.

Question 2

Is this skill compatible with all programming languages?

Accepted Answer

Yes, the architectural patterns provided are language-agnostic and apply to unit, integration, and end-to-end testing across most development stacks.

Question 3

What is the Red-Green-Refactor pattern in this context?

Accepted Answer

It is a workflow where Claude ensures a test fails (Red), writes the minimal code to make it pass (Green), and then cleans up the code (Refactor) while ensuring the test stays passing.

Question 4

How does it handle side-effect verification?

Accepted Answer

The skill provides a specific pattern for testing side effects by explicitly verifying state before the action, performing the action, and then verifying the changed state after.

Question 5

How does this skill improve code architecture?

Accepted Answer

It utilizes the Architecture-Testability duality principle to highlight where hard-to-test code indicates underlying design issues like high coupling or low cohesion.
