I ran this test locally, and it doesn't fail against the main branch

@emdneto I apologize for the confusion. Could you clarify what you would like me to address?

@Annosha The test should fail on main and raise and exception (as reported in the issue). If it doesn't fail with the current code it means it's not a good test to evaluate if the fix is working.

@xrmx and @emdneto The test is failing after fixes in testing logic. This failure confirms that the test accurately detects the issue. Here is the test log on my machine:
test-fail-for-PR-OTEL-Propagators-NONE-vlaue
Could you please review this on your end and advise on any further improvements needed?

I was expecting something like that: this should fail when running against main with the ValueError present on the issue

        global_textmap = propagate.get_global_textmap()
        self.assertIsInstance(global_textmap, composite.CompositePropagator)
        self.assertEqual(len(global_textmap._propagators), 0)

def test_propagators(propagators):
self.assertEqual(
propagators, []
) # Expecting an empty list of propagators

mock_compositehttppropagator.configure_mock(
**{"side_effect": test_propagators}
)
