Testing Patterns
Foundational testing practices applicable across languages and frameworks.
Rules
- Write tests for happy paths and error cases
- Test edge cases and boundary conditions
- Each test should test one thing
- Tests should be deterministic and repeatable
- Use descriptive test names that explain the scenario
Checklist
- Happy path is covered
- Error cases are tested
- Edge cases are identified and tested
- Tests are independent and can run in any order
- Test data is isolated per test
- No flaky tests in the suite
Pitfalls
- Testing implementation details instead of behavior
- Not testing error paths
- Shared mutable state between tests
- Tests that depend on execution order
