## Best Practices
|
||||
|
||||
### Writing Effective Tests
|
||||
|
||||
1. **Test Behavior, Not Implementation**: Focus on what the code should do, not how it does it
|
||||
2. **Keep Tests Independent**: Each test should be able to run in isolation
|
||||
3. **Use Descriptive Names**: Test names should clearly describe what is being tested
|
||||
4. **Arrange, Act, Assert**: Structure tests with clear setup, execution, and verification phases
|
||||
|
||||
### Test Organization
|
||||
|
||||
- **Colocation**: Place test files near the code they test
|
||||
- **Naming Conventions**: Use consistent naming patterns for test files and functions
|
||||
- **Test Categories**: Organize tests by type (unit, integration, e2e)

1. **Write Failing Test**: Start with a test that describes the desired behavior
|
||||
2. **Implement Feature**: Write the minimum code to make the test pass

3. **Refactor**: Improve code quality while keeping tests green

### Test-Driven Development (TDD)
|

|
||||
- Write tests before implementation
|
||||
- Use tests to guide design decisions
|
||||
- Maintain fast feedback loops
|
||||
|
||||
### Continuous Testing
|

|
||||
- Run tests automatically on code changes
|
||||
- Integrate testing into development workflow
|

- Use pre-commit hooks for test validation
