I tried this tool on tests/storage/merge_test.py, and it save the uninteresting
work of replacing assertXXX methods with asserts and pytest.raises.

SeeĀ https://gerrit.ovirt.org/c/95703 - mostly written by the tool.

This can save lot of time converting legacy tests.

Get it from https://pypi.org/project/unittest2pytest/
