[TEST-PLUGIN-SKILL: testing]

When to Use This Skill

Use this skill when:

• Writing new tests
• Improving test coverage
• Refactoring test code
• Setting up test infrastructure

Test Structure

class TestFeatureName:
    """Tests for specific feature."""
    
    def test_specific_behavior(self) -> None:
        """One test, one assertion pattern."""
        # Arrange
        input_data = create_test_data()
        
        # Act
        result = function_under_test(input_data)
        
        # Assert
        assert result == expected_value

Best Practices

1. Naming: test_<behavior>_<condition>_<expected>
2. Isolation: Each test independent, use fixtures
3. Coverage: Test happy path, edge cases, errors
4. Speed: Keep unit tests fast (<100ms each)
