Testing Strategies Skill

The best way to structure testing is to define a comprehensive strategy that applies unit, integration, and E2E tests across the software lifecycle, using structured patterns like AAA to replace guesswork with confidence.

To apply the AAA pattern, structure tests into Arrange, Act, and Assert phases, and use precise mocking rules to isolate components, ensuring your testing strategy remains systematic and repeatable.

You need TDD cycles when establishing a repeatable quality assurance framework, guiding you through test creation and code implementation to ensure coverage targets are met and changed code is prioritized.

Set coverage targets by outlining specific ranges and prioritizing changed code, ensuring your testing strategy focuses on meaningful quality assurance while avoiding over-testing and reducing waste.

Over-testing creates waste and limitations in your workflow, so you should not write tests for specific actions identified by practical don't-test rules that distinguish unnecessary testing scope from valuable quality assurance.
