description: "Framework-agnostic testing principles. Extends core-coding-standards with test-specific patterns. Use when writing, reviewing, or debugging tests."
Principles
- Test behavior, not implementation details
- Prefer integration tests over unit tests (Testing Trophy)
- Arrange-Act-Assert (AAA) pattern in every test
- Tests must be independent β no shared mutable state
- Keep tests small and focused β one behavior per test
- Name tests to describe the behavior being verified
- Optimize for confidence, not coverage percentage
- Don't chase 100% coverage β test what matters
Rules
See rules/ for detailed patterns.
