testtools NEWS

Improvements
------------
* New matcher "Annotate" that adds a simple string message to another matcher,
much like the option 'message' parameter to standard library assertFoo
methods.
* New matchers "Not" and "MatchesAll". "Not" will invert another matcher, and
"MatchesAll" that needs a successful match for all of its arguments.
* On Python 2.4, where types.FunctionType cannot be deepcopied, testtools will
now monkeypatch copy._deepcopy_dispatch using the same trivial patch that
added such support to Python 2.5. The monkey patch is triggered by the
absence of FunctionType from the dispatch dict rather than a version check.
Bug #498030.
* On windows the test 'test_now_datetime_now' should now work reliably.
* TestCase.getUniqueInteger and TestCase.getUniqueString now have docstrings.
* TestCase.getUniqueString now takes an optional prefix parameter, so you can
now use it in circumstances that forbid strings with '.'s, and such like.
* testtools.testcase.clone_test_with_new_id now uses copy.copy, rather than
copy.deepcopy. Tests that need a deeper copy should use the copy protocol to
control how they are copied. Bug #498869.
* The backtrace test result output tests should now pass on windows and other
systems where os.sep is not '/'.
0.9.2
~~~~~
Python 3 support, more matchers and better consistency with Python 2.7 --
you'd think that would be enough for a point release. Well, we here on the
testtools project think that you deserve more.
We've added a hook so that user code can be called just-in-time whenever there
is an exception, and we've also factored out the "run" logic of test cases so
that new outcomes can be added without fiddling with the actual flow of logic.
It might sound like small potatoes, but it's changes like these that will
bring about the end of test frameworks.
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)
0.9.1
~~~~~
The new matcher API introduced in 0.9.0 had a small flaw where the matchee
would be evaluated twice to get a description of the mismatch. This could lead
to bugs if the act of matching caused side effects to occur in the matchee.
Since having such side effects isn't desirable, we have changed the API now
before it has become widespread.
Changes
-------
* Matcher API changed to avoid evaluating matchee twice. Please consult
the API documentation.
* TestCase.getUniqueString now uses the test id, not the test method name,
which works nicer with parameterised tests.
Improvements
------------
* Python2.4 is now supported again.
0.9.0
~~~~~
This release of testtools is perhaps the most interesting and exciting one
it's ever had. We've continued in bringing together the best practices of unit
testing from across a raft of different Python projects, but we've also
extended our mission to incorporating unit testing concepts from other
languages and from our own research, led by Robert Collins.
We now support skipping and expected failures. We'll make sure that you
up-call setUp and tearDown, avoiding unexpected testing weirdnesses. We're
now compatible with Python 2.5, 2.6 and 2.7 unittest library.
All in all, if you are serious about unit testing and want to get the best
thinking from the whole Python community, you should get this release.
Improvements
------------
* A new TestResult API has been added for attaching details to test outcomes.
This API is currently experimental, but is being prepared with the intent
of becoming an upstream Python API. For more details see pydoc
testtools.TestResult and the TestCase addDetail / getDetails methods.
* assertThat has been added to TestCase. This new assertion supports
a hamcrest-inspired matching protocol. See pydoc testtools.Matcher for
details about writing matchers, and testtools.matchers for the included
matchers. See http://code.google.com/p/hamcrest/.
* Compatible with Python 2.6 and Python 2.7
* Failing to upcall in setUp or tearDown will now cause a test failure.
While the base methods do nothing, failing to upcall is usually a problem
in deeper hierarchies, and checking that the root method is called is a
simple way to catch this common bug.
* New TestResult decorator ExtendedToOriginalDecorator which handles
downgrading extended API calls like addSkip to older result objects that
do not support them. This is used internally to make testtools simpler but
can also be used to simplify other code built on or for use with testtools.
* New TextTestResult supporting the extended APIs that testtools provides.
* Nose will no longer find 'runTest' tests in classes derived from
testtools.testcase.TestCase (bug #312257).
* Supports the Python 2.7/3.1 addUnexpectedSuccess and addExpectedFailure
TestResult methods, with a support function 'knownFailure' to let tests
trigger these outcomes.
* When using the skip feature with TestResult objects that do not support it
a test success will now be reported. Previously an error was reported but
production experience has shown that this is too disruptive for projects that
are using skips: they cannot get a clean run on down-level result objects.
