testtools 0.9.2

Improvements
------------

* A failure in setUp and tearDown now report as failures not as errors.

* Cleanups now run after tearDown to be consistent with Python 2.7's cleanup
  feature.

* ExtendedToOriginalDecorator now passes unrecognised attributes through
  to the decorated result object, permitting other extensions to the
  TestCase -> TestResult protocol to work.

* It is now possible to trigger code just-in-time after an exception causes
  a test outcome such as failure or skip. See the testtools MANUAL or
  ``pydoc testtools.TestCase.addOnException``. (bug #469092)

* New matcher Equals which performs a simple equality test.

* New matcher MatchesAny which looks for a match of any of its arguments.

* TestCase no longer breaks if a TestSkipped exception is raised with no
  parameters.

* TestCase.run now clones test cases before they are run and runs the clone.
  This reduces memory footprint in large test runs - state accumulated on
  test objects during their setup and execution gets freed when test case
  has finished running unless the TestResult object keeps a reference.
  NOTE: As test cloning uses deepcopy, this can potentially interfere if
  a test suite has shared state (such as the testscenarios or testresources
  projects use). Use the __deepcopy__ hook to control the copying of such
  objects so that the shared references stay shared.

* Testtools now accepts contributions without copyright assignment under some
  circumstances. See HACKING for details.

* Testtools now provides a convenient way to run a test suite using the
  testtools result object: python -m testtools.run testspec [testspec...].

* Testtools now works on Python 3, thanks to Benjamin Peterson.

* Test execution now uses a separate class, testtools.RunTest to run single
  tests. This can be customised and extended in a more consistent fashion than
  the previous run method idiom. See pydoc for more information.

* The test doubles that testtools itself uses are now available as part of
  the testtools API in testtols.testresult.doubles.

* TracebackContent now sets utf8 as the charset encoding, rather than not
  setting one and encoding with the default encoder.

* With python2.7 testtools.TestSkipped will be the unittest.case.SkipTest
  exception class making skips compatible with code that manually raises the
  standard library exception. (bug #490109)

Changes
-------

* TestCase.getUniqueInteger is now implemented using itertools.count. Thanks
  to Benjamin Peterson for the patch. (bug #490111)
