+Subject: [PATCH 1/2] test_dataset: remove incorrect pytest.warns() to fix
+ pytest-8
+
+Remove two incorrect `pytest.warns()` assertions to fix test failures
+with pytest-8.0.0.  Prior to this version, an exception raised would
+cause `pytest.warns()` to be ignored.  This way fixed in 8.0.0, and now
+warnings must actually be emitted prior to the exception.
+
+In `test_drop_index_labels()`, the exception is raised at the very
+beginning of the function, prior to the deprecation warning.
+
+In `test_rename_multiindex()`, the warning is not emitted at all (it is
+not applicable to the call in question).

+Subject: [PATCH 2/2] test_groupby: Clear recorded warnings for pytest-8
+ compatibility
+
+Clear the warnings recorded during the `pytest.warns()` use
+in `test_groupby_dims_property`, to fix test failures with pytest-8.0.0.
+Prior to this version, `pytest.warns()` invocation used to capture all
+warnings.  Now it only captures the warnings that match the arguments,
+and the remaining warnings are re-emitted and therefore caught by
+`recwarn` fixture.  To provide compatibility with both versions of
+pytest, clear the recorded warnings immediately after `pytest.warns()`.
+
+Fixes #8681
