</div></div>It looks like the only test files that have yield tests are:<br>
models/test_user_permissions_on_repo_groups.py<br>
models/test_user_group_permissions_on_repo_groups.py<br>
<br>
In the tests in these files, the pattern is typically:<br>
for name, perm in repo_items:<br>
yield check_tree_perms, name, perm, group, 'repository.read'<br>
<br>
for name, perm in items:<br>
yield check_tree_perms, name, perm, group, 'group.write'<br>
<br>
<br>
where:<br>
repo_items = [x for x in _get_repo_perms(group, recursive)]<br>
items = [x for x in _get_group_perms(group, recursive)]<br>
<br>
and:<br>
def check_tree_perms(obj_name, repo_perm, prefix, expected_perm):<br>
assert repo_perm == expected_perm, ('obj:`%s` got perm:`%s` should:`%s`'<br>
% (obj_name, repo_perm, expected_perm))<br>
<br>
<br>
If yield tests are a problem, what about just transforming such yield<br>
tests into simple tests? Each test function that is currently yielding<br>
new test methods would become one simple test, iterating over the<br>
items and repo_items and asserting for each combination, thus<br>
replacing the yield statement with the assert itself.<br>
<br>
This may not be as nice as a test could fail due to many different<br>
scenarios, but since there are only test files that have this problem<br>
and since such yield tests are a blocking issue as said by Ronny, such<br>
a solution could deblock pytest conversion.<br>
<br>
Thoughts?<br>
