seems like this is the only difference from the previous test. Should the error log being asserted in the test?

Good point.

One thing I don't understand is that when I added the following code at the end of the unit test (line 284), the logobs is empty, which I don't understand. I'll keep this PR for now to take more time to find the reason. This shouldn't impact the testing.

with self.assertLogs() as logobs:
    self.assertEqual(
        "ERROR:root:Any `V_dot_VAV_max` value shouldn't be zero.",
        logobs.output[0],
    )
