python-testing-patterns

Use pytest for comprehensive testing with fixtures, mocking, and TDD. Focus on isolation, coverage, and real-world scenarios.

• Test code with pytest, fixtures, and mocking
• Apply TDD and test structure (AAA pattern)
• Ensure test isolation and meaningful coverage
• Test units, integrations, and async operations

• Use AAA pattern: Arrange, Act, Assert
• Leverage fixtures for setup and teardown
• Parameterize tests for multiple input cases
• Mock external dependencies
• Maintain test independence and statelessness
• Prioritize meaningful coverage over percentage
• Support async and performance testing
• Integrate with CI/CD pipelines

1. 1.Write unit tests using pytest and TDD
2. 2.Define fixtures for setup and cleanup
3. 3.Use parametrization for multiple test cases
4. 4.Mock external services and dependencies
5. 5.Structure tests with AAA pattern
6. 6.Run tests in CI/CD pipelines
