Add client to import

[katkaypettitt]

The following error appears without importing client:

E       fixture 'client' not found
>       available fixtures: cache, capfd, capfdbinary, caplog, capsys, capsysbinary, cov, doctest_namespace, monkeypatch, no_cover, pytestconfig, record_property, record_testsuite_property, record_xml_attribute, recwarn, tmp_path, tmp_path_factory, tmpdir, tmpdir_factory
>       use 'pytest --fixtures [testpath]' for help on them.

This is remedied by importing client as suggested.

This was also the case for sitemap_tests.py. However, it is highly possible the problem was on my end—hence why the PR has been closed.

Thanks. I do think the tests ran when I put them together during the recording.

Thanks for the response, Mike! While I have you, the import statements were collapsed for the sitemap_test video but client was imported in package_tests (there was even a comment about importing it). Was it taken out for some reason?

The problem was this seems to only work if you run tests for the whole project (which loads client) but doesn't work if you run it directly. I just committed a more general fix:

Such an elegant fix! Thanks for this.
