Pytest Generation Skill

When generating tests, follow this structure.

Test Organization

• Group tests by function under test
• Use @pytest.mark.parametrize for multiple inputs
• Use fixtures for shared setup
• Follow arrange/act/assert pattern

Coverage Requirements

• Happy path (expected usage)
• Edge cases (empty strings, None, boundary values)
• Error cases (invalid input, file not found, wrong types)
• Integration (functions working together)
