Pytest Testing Guidelines

## What problem does it solve? Pytest Testing Guidelines provide a structured framework to write consistent, robust unit tests in Python, emphasizing naming conventions, mock strategies, parametrization, and comprehensive coverage.

## Core Features & Use Cases

• Standardized test naming conventions and project structure that mirror source files.
• Clear guidance on mocking with side_effect, mock_calls verification, and avoiding brittle assertions.
• Practical parametrization patterns and real-world use cases for small utilities up to large codebases.

### Quick Start Begin by reading these guidelines, then apply the templates to your tests:

• name tests after the corresponding source methods (e.g., test_my_feature)
• mock external dependencies with patch or patch.object
• verify mock interactions using a single object-level mock_calls assertion
