pytest-cmake
Provide CMake module for Pytest
Decision gist · record as of 2026-08-14
Yes, if you maintain a CMake project with Python tests or C++ code with Python bindings. The package has low install friction, permissive licensing, and no known vulnerabilities. The aging maintenance status is a minor concern for a stable, narrowly-scoped integration tool, but the repository remains active and supports current Python versions.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires CMake and pytest to be installed; pytest-cmake is a CMake module, not a standalone Python tool
- Low friction install with a single runtime dependency on pytest.
- Last release was 223 days ago; repository is active but aging.

What it is and what it does
pytest-cmake is a CMake module that bridges Pytest and CMake, allowing Python tests to be discovered and run as part of a C++ project's build system. It provides a find_package function to locate Pytest and a pytest_discover_tests function that automatically converts Python tests into CTest entries, which can then be executed and reported alongside native C++ tests.
The package is designed for mixed-language projects—particularly those with C++ libraries that expose Python bindings. Instead of running Python tests separately, developers can integrate them into their CMake workflow, controlling test environment variables like library and Python paths, filtering test names, and declaring dependencies on compiled targets.
Use it for
- Integrate Python unit tests for C++ extension modules into a unified CMake test suite
- Automatically discover and register Python tests as CTest entries without manual configuration
- Set up controlled test environments by prepending library and Python paths before test execution
- Run mixed C++ and Python tests in a single CI/CD pipeline using ctest
