How can I use pytest.raises with multiple exceptions?
Pass the exceptions as a tuple to raises:
with pytest.raises( (MachineError, NotImplementedError) ): verb = ...In the source for pytest, pytest.raises may:
- catch
expected_exception; or - pass
expected_exceptionto aRaisesContextinstance, which then usesissubclassto check whether the exception was one you wanted.
In Python 3, except statements can take a tuple of exceptions. The issubclass function can also take a tuple. Therefore, using a tuple should be acceptable in either situation.
