# 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 80%+ coverage on business logic; 100% on critical paths
|
|
- 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
