Part of twisted.trial View Source
This code is for Trial's internal use. Do NOT use this code if you are writing tests. It is subject to change at the Trial maintainer's whim. There is nothing here in this module for you to use unless you are maintaining Trial.
Any non-Trial Twisted code that uses this module will be shot.

|Function||excInfoOrFailureToExcInfo||Coerce a Failure to an _exc_info, if err is a Failure.|
|Function||suppress||Sets up the .suppress tuple properly, pass options to this method as you would the stdlib warnings.filterwarnings()|
|Function||getPythonContainers||Walk up the Python tree from method 'meth', finding its class, its module and all containing packages.|
|Function||acquireAttribute||Go through the list 'objects' sequentially until we find one which has attribute 'attr', then return the value of that attribute. If not found, return 'default' if set, otherwise, raise AttributeError.|
|Function||findObject||Get a fully-named package, module, module-global object or attribute. Forked from twisted.python.reflect.namedAny.|
|Class||_Janitor||The guy that cleans up after you.|
|Function||_runSequentially||Run the given callables one after the other. If a callable returns a Deferred, wait until it has finished before running the next callable.|
|Class||_NoTrialMarker||No trial marker file could be found.|
|Function||_removeSafely||Safely remove a path, recursively.|
|Class||_WorkingDirectoryBusy||A working directory was specified to the runner, but another test run is currently using that directory.|
|Function||_unusedTestDirectory||Find an unused directory named similarly to
So, to use this with a .suppress magic attribute you would do the following:
>>> from twisted.trial import unittest, util >>> import warnings >>> >>> class TestFoo(unittest.TestCase): ... def testFooBar(self): ... warnings.warn("i am deprecated", DeprecationWarning) ... testFooBar.suppress = [util.suppress(message='i am deprecated')] ... >>>
Note that as with the todo and timeout attributes: the module level
attribute acts as a default for the class attribute which acts as a default
for the method attribute. The suppress attribute can be overridden at any
level by specifying
.suppress = 
Returns a tuple of (bool, obj). If bool is True, the named object exists and is returned as obj. If bool is False, the named object does not exist and the value of obj is unspecified.
|Parameters||callables||An iterable of callables that take no parameters.|
|stopOnFirstError||If True, then stop running callables as soon as one raises an exception or fires an errback. False by default.|
path does not contain a node named
_NoTrialmarker exception is
raised and the path is not removed.
Once a directory is found, it will be locked and a marker dropped into it to identify it as a trial temporary directory.
|Parameters||base||A template path for the discovery process. If this path exactly cannot be
used, a path which varies only in a suffix of the basename will be used
instead. (type: |
|Returns||A two-tuple. The first element is a |
