Python Testing Patterns

What it does

This skill provides guidance and code examples for implementing common Python testing patterns. It helps developers write more robust, maintainable tests using techniques like mocking, patching, test fixtures, and parameterized tests. The skill aims to improve the quality of Python code through better testing practices.

When to use it

• When you need help writing unit tests for a specific function or class in your Python project.
• To understand how to effectively mock dependencies during testing.
• If you're struggling with setting up test fixtures and want examples of best practices.
• For assistance creating parameterized tests to cover various input scenarios efficiently.

Key capabilities

• Mocking
• Patching
• Test Fixtures
• Parameterized Tests

Example prompts

• "Show me an example of how to mock a database connection in a Python unit test."
• "How can I use patching to replace a function call with a mock object?"
• "Generate a parameterized test for this function, covering positive and negative inputs."

Tips & gotchas

This skill assumes you have basic familiarity with Python and the unittest framework. The effectiveness of the generated code depends on providing clear context about the code being tested.
