Function Details

deferredError(d, timeout=None)

Waits for deferred to fail, and it returns the Failure.

If the deferred succeeds, raises FailTest.

deferredResult(d, timeout=None)

Waits for a Deferred to arrive, then returns or throws an exception, based on the result.

extract_tb(tb, limit=None)

Extract a list of frames from a traceback, without unittest internals.

Functionally identical to traceback.extract_tb, but cropped to just the test case itself, excluding frames that are part of the Trial testing framework.

format_exception(eType, eValue, tb, limit=None)

A formatted traceback and exception, without exposing the framework.

I am identical in function to traceback.format_exception, but I screen out frames from the traceback that are part of the testing framework itself, leaving only the code being tested.

wait(d, timeout=10)

This function is unstable.

Waits (spins the reactor) for a Deferred to arrive, then returns or throws an exception, based on the result. The difference between this and deferredResult is that it actually throws the original exception, not the Failure, so synchronous exception handling is much more sane.

Variable Details

_failureConditionals

Type:: list
Value:: ['fail', 'failIf', 'failUnless', 'failUnlessRaises', 'failUnlessEqual', 'failUnlessIdentical', 'failIfEqual', 'assertApproximates']
