para-pytest 0.1.0

Run pytest tests in parallel chunks for faster test execution

Parallel Pytest (para-pytest)

Run pytest tests in parallel chunks for significantly faster test execution.

Installation

pip install para-pytest

Quick Start

# Run with default settings (4 chunks)
para-pytest

# Specify number of chunks
para-pytest --chunks 8

# Specify test path
para-pytest --path tests/

Use Cases

Local Development

Speed up your test suite during development:

# Before (sequential execution)
pytest tests/

# After (parallel execution)
para-pytest --chunks 4

Continuous Integration

Add to your GitHub Actions workflow:

name: Tests

on: [push, pull_request]

jobs: 
	test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - uses: actions/setup-python@v5
        with:
          python-version: '3.12.3'

      - name: Install dependencies
        run: |
          pip install -r requirements.txt
          pip install para-pytest

      - name: Run tests
        run: para-pytest --chunks 4 --path tests/

Or use the Github Action:

- uses: ALHelton/parallel-pytest@v1
  with:
    chunks: 8
    path: tests/

Python API

from para_pytest import ParaPytestRunner

runner = ParaPytestRunner(chunks=4, pytest_args=['tests/'])
exit_code = runner.run()

How It Works

1. Collects all tests from pytest
2. Splits tests into equal chunks
3. Runs chunks in parallel using asyncio
4. Aggregates and displays results

Requirements

• Python 3.9+
• pytest 7.0+
