pytest-optimized-parametrization

---

This repository contains a solution to optimize the test parametrization process in pytest, specifically addressing performance issues that arise in large test suites with numerous tests and fixtures. By implementing a filtering mechanism within the pytest_generate_tests hook, this solution ensures that only the relevant tests matching specified markers or keywords are parametrized, significantly reducing unnecessary overhead and improving overall test execution performance.

Key Features

• Efficient Parametrization: Dynamically parametrize only the tests that match specified markers or keywords, reducing collection time and resource consumption.
• Customizable Filtering: Easily adjust the filtering mechanism to suit different testing needs and configurations.
• Enhanced Performance: Focus computational resources on relevant tests, improving test execution speed and developer productivity.
• Detailed Logging: Comprehensive logging to trace the parametrization process and identify tests that are included or excluded based on markers and keywords.

Contents

• pytest_generate_tests Hook: A customized implementation of the pytest_generate_tests hook to optimize test parametrization.
• Helper Functions: Functions to evaluate expressions, check marker presence, and determine if tests should be skipped based on markers or keywords.
• Examples and Usage: Sample code and usage instructions to demonstrate how to integrate and use the optimized parametrization in your own pytest setup.

Getting Started

1. Clone the Repository:

   git clone https://github.com/yourusername/pytest-optimized-parametrization.git

2. Install Dependencies: Ensure you have pytest installed. You can install it via pip if needed:

   pip install pytest

3. Integrate the Custom Hook: Add the provided pytest_generate_tests hook and helper functions to your pytest configuration by placing them in a conftest.py.

4. Run Tests with Markers: Use markers to specify which tests to parametrize and run, leveraging the optimized filtering mechanism:

   pytest -m "your_marker"
