pytest-xdist-tracker

This plugin allows us to keep artifact after running test with xdist (parallel)

Installation

pip install pytest-xdist-tracker

Using

For example, we use pytest-xdist for running tests in parallel and we have a test that fails from time to time. That definitely a flaky/coupled test that fails because before were executed tests that keep after self some unexpected state for our failed test

pytest-xdist-tracker can help with that case

It stores artifact after execution like this one xdist_stats_worker_gw1.txt where gw1 is number of xdist node

Then we can reproduce tests which were run in particular node where failure happened

pytest --from-xdist-stats=xdist_stats_worker_gw1.txt

It will collect tests as usual but will filter by our tests

note: this plugin works only with pytest-xdist
