How To Install python-pytest-xdist on Debian 9
Introduction
In this tutorial we learn how to install python-pytest-xdist on Debian 9.
What is python-pytest-xdist
python-pytest-xdist is:
The pytest-xdist plugin extends py.test with some unique test execution modes:
- 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.
- Load-balancing: if you have multiple CPUs or hosts you can use those for a combined test run. This allows one to speed up development or to use special resources of remote machines.
- Multi-Platform coverage: you can specify different Python interpreters or different platforms and run tests in parallel on all of them.
Before running tests remotely, py.test efficiently synchronizes your program source code to the remote place. All test results are reported back and displayed to your local test session. You may specify different Python versions and interpreters.
