- Updated the coding rule descriptions to emphasize readability, meaningful comments, and test verification. - Revised guidelines to clarify the importance of avoiding boilerplate while maintaining readability. - Enhanced the testing rules to set a minimum coverage threshold of 75% for business logic and specified criteria for test scenarios. - Introduced a mechanism for handling skipped tests, categorizing them as legitimate or illegitimate, and outlined resolution steps. These changes aim to improve code quality, maintainability, and testing effectiveness.

# Testing
|
|
|
|
- Structure every test with Arrange / Act / Assert section comments using language-appropriate syntax (`# Arrange` for Python, `// Arrange` for C#/Rust/JS/TS)
|
|
- One assertion per test when practical; name tests descriptively: `MethodName_Scenario_ExpectedResult`
|
|
- Test boundary conditions, error paths, and happy paths
|
|
- Use mocks only for external dependencies; prefer real implementations for internal code
|
|
- Aim for 75%+ coverage on business logic; 100% on critical paths (code paths where a bug would cause data loss, security breaches, financial errors, or system outages — identify from acceptance criteria marked as must-have or from security_approach.md). The 75% threshold is canonical — see `cursor-meta.mdc` Quality Thresholds.
|
|
- Integration tests use real database (Postgres testcontainers or dedicated test DB)
|
|
- Never use Thread Sleep or fixed delays in tests; use polling or async waits
|
|
- Keep test data factories/builders for reusable test setup
|
|
- Tests must be independent: no shared mutable state between tests
