------------------------------------------------------------------------
Thanks for the patch. Finding those skipped tests is a very good catch. Overall
the patch looks good to me, I have left some minor suggestions on the PR.
{quote}Treat --only-resource-intensive-tests in the same way as
--force-resource-intensive-tests, so it will be enough to just specify it even
with no sufficient resources.
{quote}
I'm not sure about this, IMO it makes sense the way it currently works. The
flag {{\-\-only-resource-intensive-tests}} selects the tests to run and
{{\-\-force-resource-intensive-tests}} disables the safety mechanism that
prevents running the tests if there aren't enough resources available.
On one hand, I understand that current meaning of
{{\-\-only-resource-intensive-tests}} without
{{\-\-force-resource-intensive-tests}} is "run the resource intensive tests but
only if you have resources to do so". I guess that a (convoluted) example use
case for this could be having a CircleCI job for running resource intensive
tests. This job would success in LOWRES and MIDRES without running any tests
due to the lack of resources, and it would actually run the tests in HIGHRES.
On the other hand, I understand that in most cases when you use
{{\-\-only-resource-intensive-tests}} probably you are going to want to run
with or without the resources. I don't think that any of the approaches is
wrong or much better than the other, so I'm more inclined to preserve the
current behaviour. We can always add some more information in the description
of the flags if we think that this is going to be confusing for users. What do
you think? Am I missing something?

> Key: CASSANDRA-16841
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16841
> Project: Cassandra
> Issue Type: Bug
> Components: Test/dtest/python
> Reporter: Ruslan Fomkin
> Assignee: Ruslan Fomkin
> Priority: Normal
> Time Spent: 50m
> Remaining Estimate: 0h
>
> An issue, which I was hit:
> When one class in a dtest file is marked as resource intensive, then all
> tests in all classes are treated as resource intensive. For example,
> [repair_tests/repair_test.py|https://github.com/apache/cassandra-dtest/blob/trunk/repair_tests/repair_test.py]
> contains three classes and the last class is marked as resource intensive:
> {code:java}
> @pytest.mark.resource_intensive
> class TestRepairDataSystemTable(Tester):
> {code}
> So if I try to run an unmarked class:
> {code:java}
> pytest --cassandra-dir=../cassandra repair_tests/repair_test.py::TestRepair
> --collect-only --skip-resource-intensive-tests
> {code}
> then all tests are ignored
> {code:java}
> collected 36 items / 36 deselected
> {code}
> This is because a test is treated to be marked if any class in the same file
> has the mark. This bug was introduced in the fix of CASS-16399. Before only
> upgrade tests had such behaviour, i.e., if a class is marked as upgrade test,
> then all tests are upgrade test in the file.
>
> This bug, for example, means that if the same file contains one class marked
> with vnodes and another class with no_vnodes, then no tests will be executed
> in the file.
> I also noticed another issue that If a test run is executed with the argument
> {{-only-resource-intensive-tests}} and there is no sufficient resources for
> resource intensive tests, then no tests were executed. Thus it was necessary
> to provide {{-force-resource-intensive-tests}} in addition.
> Suggestions for the solutions:
> # Require to mark each class and remove the special case of upgrade tests.
> This will simplify the implementation and might be more obvious for new
> comers.
> # Treat {{-only-resource-intensive-tests}} in the same way as
> {{-force-resource-intensive-tests}}, so it will be enough to just specify it
> even with no sufficient resources.
