No—unless you are maintaining legacy code already using this plugin and cannot migrate. The package is abandoned with no maintenance signal since 2022-01-08. For new MPI testing projects, evaluate actively maintained alternatives or consider building on pytest directly. If you must use it, verify compatibility with your Python version first.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires MPI to be installed on your system; the package is abandoned and may not work with Python versions beyond those listed in classifiers (3.5–3.9).
- Low install friction with a single runtime dependency on pytest.
- However, the package is abandoned—last release was over 1679 days ago with no recent maintenance activity.

What it is and what it does
pytest-mpi is a pytest plugin that adds MPI-aware testing capabilities to the pytest framework. It provides a marker decorator (`@pytest.mark.mpi`) that allows you to tag tests to run only under MPI execution, making it easier to organize and filter tests in codebases that use Message Passing Interface for parallel or distributed computing.
The plugin is designed for developers working on MPI-related code who want to integrate MPI tests into their standard pytest workflow. However, the package has been abandoned, with the latest release on 2022-01-08. It was last tested against Python versions 3.5 through 3.9, and compatibility with newer Python versions or pytest releases is unknown.
Use it for
- Mark and selectively run MPI-specific tests in a pytest suite without running them in serial mode.
- Organize test collections for distributed memory projects that use MPI for parallel computing.
- Filter tests in CI/CD pipelines to run MPI tests only on systems with MPI installed and configured.

More Testing packages
Pluggy provides a plugin system that lets you define hook specifications and register implementations to be called in sequence, enabling extensible Python applications without tight coupling.
Install it if you're building an extensible application or framework.
pytest is a testing framework that lets you write test functions using plain assert statements and automatically discovers and runs them, with detailed failure reporting.
virtualenv creates isolated Python environments where packages can be installed independently without affecting the system Python or other projects.
Coverage.py measures which lines of Python code are executed during test runs, reporting coverage percentages and identifying untested code paths.
Install it if you want to measure test completeness or enforce coverage thresholds in your project.
pytest-asyncio is a pytest plugin that enables writing and running async test functions using the asyncio library, allowing developers to await code directly within test cases.
Install it if you write tests for any asyncio-based code.
