To structure pytest tests, enforce clear naming conventions for test functions and organize files following standard project structure. Use pytest fixtures with appropriate scoping and yield for cleanup to ensure maintainable and independent test execution across your Python project.

The best way to parametrize pytest tests is using the parametrization feature with explicit IDs. This approach promotes efficient testing by clearly mapping various inputs to their expected outcomes, ensuring edge cases are covered without duplicating test function code.

Configure test coverage targets directly in pyproject.toml to define clear goals for code quality. Setting these thresholds ensures your Python project meets reliability requirements before merging by enforcing minimum coverage percentages across the test suite.

Common pytest anti-patterns include using time.sleep for synchronization and relying on shared mutable state across tests. Avoiding these practices ensures your tests remain independent, reliable, and aligned with TDD principles for robust Python code.

Yes, you can use this Skill to guide TDD practices. It provides comprehensive guidelines to ensure your tests are well-structured, cover edge cases through parametrization, and meet defined coverage requirements before merging new Python features.
