Testing Skill

[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

python
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)
