+Subject: [PATCH] Fix warning tests to work correctly without -Werror
+
+Use pytest.warns() instead of pytest.raises() to test for warnings,
+in order to make these tests work correctly without -Werror.  This does
+not change the behavior with -Werror.
+
+While -Werror is useful for package maintainers / CI, it is problematic
+for testing on end user systems.  For end users, it is important whether
+the particular version of package is going to work on their setup,
+not whether it does not use anything that's deprecated but still
+working.
