In a trial test case like this:
-----------------------------------------------------------------------------------------------------------------------
*def testFailureFromDeferredList(self):*
* d = defer.fail(ValueError('bad value'))*
* return self.assertFailure(defer.gatherResults([d]), ValueError)*
-----------------------------------------------------------------------------------------------------------------------
I get the following FAIL and ERROR:
-----------------------------------------------------------------------------------------------------------------------
*[FAIL]
*
*Traceback (most recent call last):*
* File "/home/gjorge/tmp/
buildbot.net/python_sandbox/local/lib/python2.7/site-packages/twisted/trial/_asynctest.py",
line 74, in _eb*
* raise self.failureException(output)*
*twisted.trial.unittest.FailTest: *
*Expected: (<type 'exceptions.ValueError'>,)*
*Got:*
*[Failure instance: Traceback (failure with no frames): <class
'twisted.internet.defer.FirstError'>: FirstError[#0, [Failure instance:
Traceback (failure with no frames): <type 'exceptions.ValueError'>: bad
value*
*]]*
*]*
*
*
*
===============================================================================
*
*[ERROR]*
*Traceback (most recent call last):*
*Failure: exceptions.ValueError: bad value*
-----------------------------------------------------------------------------------------------------------------------
If I try to remedy this by asserting I get a defer.FirstError instead of a
ValueError:
-----------------------------------------------------------------------------------------------------------------------
*def testFailureFromDeferredList(self):*
* d = defer.fail(ValueError('bad value'))*
* return self.assertFailure(defer.gatherResults([d]), defer.FirstError)*
-----------------------------------------------------------------------------------------------------------------------
I still get an Error:
-----------------------------------------------------------------------------------------------------------------------
*[ERROR]*
*Traceback (most recent call last):*
*Failure: exceptions.ValueError: bad value*
-----------------------------------------------------------------------------------------------------------------------
Is there another way to assert ValueError was raised?
Thanks,
Jorge
