For some time now, pytest has supported setting where a cache directory that it will use is located (and in turn has logic to re-use this cache and speed things up when possible). When running the pytest tests on Azure Pipelines, our source directory is read-only and we now see a warning about being unable to create the .pytest_cache directory as the default is in the same place as pytest.ini. Set cache_dir to /tmp/.pytest_cache so that it will always be placed in a read/write location.

I think hard-coding to /tmp here ends up being less problematic but I am open to suggestions. We could even just ignore the warning, I only spotted it when seeing why a test had otherwise failed. --- test/py/pytest.ini | 1 + 1 file changed, 1 insertion(+)
