> The [dtest project|https://github.com/apache/cassandra-dtest] uses pytest as
> test runner of choice for executing tests on builds.apache.org or CircleCI.
> The pytest dependency has recently been upgrade to 3.6, but couldn't be
> upgrade to the most recent 3.8 version, due to issues described below.
> Before test execution, the {{run_dtests.py}} script will gather a list of all
> tests:
> {{./run_dtests.py --dtest-print-tests-only}}
> Afterwards pytest can be started with any of the output lines as argument.
> With pytest-3.8 however, the output format changed and preventing pytest to
> find the test:
> {{pytest
> upgrade_tests/upgrade_supercolumns_test.py::TestSCUpgrade::test_upgrade_super_columns_through_limited_versions}}
> vs
> {{pytest
> upgrade_supercolumns_test.py::TestSCUpgrade::test_upgrade_super_columns_through_limited_versions}}
> The underlying issue appears to be the changes in the {{pytest
> --collect-only}} output, consumed in {{run_dtests.py}}, which now includes a
> <Package> element that needs to be parsed as well to derive at the path as we
> did before. We'd have to parse the new output and assemble the correct paths
> again, so we can use run_dtests.py as we did before with pytest 3.6.
