Pytest xdist plugin for distributed testing and loop-on-failing modes

The pytest-xdist plugin extends py.test with some unique test execution modes

  • Test run parallelization if you have multiple CPUs or hosts you can use those for a combined test run. This allows to speed up development or to use special resources of remote machines.
  • –boxed not available on Windows run each test in a boxed subprocess to survive SEGFAULTS or otherwise dying processes
  • –looponfail run your tests repeatedly in a subprocess. After each run py.test waits until a file in your project changes and then re-runs the previously failing tests. This is repeated until all tests pass after which again a full run is performed.
  • Multi-Platform coverage you can specify different Python interpreters or different platforms and run tests in parallel on all of them.
