Thanks for your feedback. This code also works on Windows and on other Unix systems (OSX, Solaris) ---- The new methods successResultOf and failureResultOf looks good, but I think they only work with deferred that already have a result. ---- I am aware that the whole thing is fragile... and I am aware of the consequences of using internal non-public methods. I checked the code from twisted.trial.unittest.TestCase but I could not spot how it waits for deferreds execution. What part of twisted.trial.unittest.TestCase executes and waits for the deferred? Can I use that code to implement something similar to successResultOf and failureResultOf but which also executes the deferred?
