Testtools

~~~~~~

Brown paper bag fix: failed to document the need for setup to be able to use
extras. Compounded by pip not supporting setup_requires.

Changes
-------

* setup.py now can generate egg_info even if extras is not available.
Also lists extras in setup_requires for easy_install.
(Robert Collins, 1102464)

~~~~~~

Changes
-------

* ``python -m testtools.run --load-list`` will now preserve any custom suites
(such as ``testtools.FixtureSuite`` or ``testresources.OptimisingTestSuite``)
rather than flattening them.
(Robert Collins, 827175)

* Testtools now depends on extras, a small library split out from it to contain
generally useful non-testing facilities. Since extras has been around for a
couple of testtools releases now, we're making this into a hard dependency of
testtools. (Robert Collins)

* Testtools now uses setuptools rather than distutils so that we can document
the extras dependency. (Robert Collins)

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

* Testtools will no longer override test code registered details called
'traceback' when reporting caught exceptions from test code.
(Robert Collins, 812793)

~~~~~~

Changes
-------

* ``testtools.run discover`` will now sort the tests it discovered. This is a
workaround for http://bugs.python.org/issue16709. Non-standard test suites
are preserved, and their ``sort_tests()`` method called (if they have such an
attribute). ``testtools.testsuite.sorted_tests(suite, True)`` can be used by
such suites to do a local sort. (Robert Collins, 1091512)

* ``ThreadsafeForwardingResult`` now defines a stub ``progress`` method, which
fixes ``testr run`` of streams containing progress markers (by discarding the
progress data). (Robert Collins, 1019165)

~~~~~~

Changes
-------

* ``run.TestToolsTestRunner`` now accepts the verbosity, buffer and failfast
arguments the upstream python TestProgram code wants to give it, making it
possible to support them in a compatible fashion. (Robert Collins)

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

* ``testtools.run`` now supports the ``-f`` or ``--failfast`` parameter.
Previously it was advertised in the help but ignored.
(Robert Collins, 1090582)

* ``AnyMatch`` added, a new matcher that matches when any item in a collection
matches the given matcher. (Jonathan Lange)

* Spelling corrections to documentation. (Vincent Ladeuil)

* ``TestProgram`` now has a sane default for its ``testRunner`` argument.
(Vincent Ladeuil)

* The test suite passes on Python 3 again. (Robert Collins)

~~~~~~

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

* ``content_from_file`` and ``content_from_stream`` now accept seek_offset and
seek_whence parameters allowing them to be used to grab less than the full
stream, or to be used with StringIO streams. (Robert Collins, 1088693)

~~~~~~

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

* ``DirContains`` correctly exposed, after being accidentally hidden in the
great matcher re-organization of 0.9.17. (Jonathan Lange)
