10 * Cleanups can raise ``testtools.MultipleExceptions`` if they have multiple
11 exceptions to report. For instance, a cleanup which is itself responsible for
12 running several different internal cleanup routines might use this.
14 * Code duplication between assertEqual and the matcher Equals has been removed.
16 * In normal circumstances, a TestCase will no longer share details with clones
17 of itself. (Andrew Bennetts, bug #637725)
23 Nothing major in this release, just enough small bits and pieces to make it
24 useful enough to upgrade to.
26 In particular, a serious bug in assertThat() has been fixed, it's easier to
27 write Matchers, there's a TestCase.patch() method for those inevitable monkey
28 patches and TestCase.assertEqual gives slightly nicer errors.
33 * 'TestCase.assertEqual' now formats errors a little more nicely, in the
36 * Added `PlaceHolder` and `ErrorHolder`, TestCase-like objects that can be
37 used to add results to a `TestResult`.
39 * 'Mismatch' now takes optional description and details parameters, so
40 custom Matchers aren't compelled to make their own subclass.
42 * jml added a built-in UTF8_TEXT ContentType to make it slightly easier to
43 add details to test results. See bug #520044.
45 * Fix a bug in our built-in matchers where assertThat would blow up if any
46 of them failed. All built-in mismatch objects now provide get_details().
48 * New 'Is' matcher, which lets you assert that a thing is identical to
51 * New 'LessThan' matcher which lets you assert that a thing is less than
54 * TestCase now has a 'patch()' method to make it easier to monkey-patching
55 objects in tests. See the manual for more information. Fixes bug #310770.
57 * MultiTestResult methods now pass back return values from the results it
63 This release fixes some obscure traceback formatting issues that probably
64 weren't affecting you but were certainly breaking our own test suite.
69 * Jamu Kakar has updated classes in testtools.matchers and testtools.runtest
70 to be new-style classes, fixing bug #611273.
75 * Martin[gz] fixed traceback handling to handle cases where extract_tb returns
76 a source line of None. Fixes bug #611307.
78 * Martin[gz] fixed an unicode issue that was causing the tests to fail,
81 * testtools now handles string exceptions (although why would you want to use
82 them?) and formats their tracebacks correctly. Thanks to Martin[gz] for
88 This release overhauls the traceback formatting layer to deal with Python 2
89 line numbers and traceback objects often being local user encoded strings
90 rather than unicode objects. Test discovery has also been added and Python 3.1
91 is also supported. Finally, the Mismatch protocol has been extended to let
92 Matchers collaborate with tests in supplying detailed data about failures.
97 * testtools.utils has been renamed to testtools.compat. Importing
98 testtools.utils will now generate a deprecation warning.
103 * Add machinery for Python 2 to create unicode tracebacks like those used by
104 Python 3. This means testtools no longer throws on encountering non-ascii
105 filenames, source lines, or exception strings when displaying test results.
106 Largely contributed by Martin[gz] with some tweaks from Robert Collins.
108 * James Westby has supplied test discovery support using the Python 2.7
109 TestRunner in testtools.run. This requires the 'discover' module. This
112 * Python 3.1 is now supported, thanks to Martin[gz] for a partial patch.
113 This fixes bug #592375.
115 * TestCase.addCleanup has had its docstring corrected about when cleanups run.
117 * TestCase.skip is now deprecated in favour of TestCase.skipTest, which is the
118 Python2.7 spelling for skip. This closes bug #560436.
120 * Tests work on IronPython patch from Martin[gz] applied.
122 * Thanks to a patch from James Westby testtools.matchers.Mismatch can now
123 supply a get_details method, which assertThat will query to provide
124 additional attachments. This can be used to provide additional detail
125 about the mismatch that doesn't suite being included in describe(). For
126 instance, if the match process was complex, a log of the process could be
127 included, permitting debugging.
129 * testtools.testresults.real._StringException will now answer __str__ if its
130 value is unicode by encoding with UTF8, and vice versa to answer __unicode__.
131 This permits subunit decoded exceptions to contain unicode and still format
137 More matchers, Python 2.4 support, faster test cloning by switching to copy
138 rather than deepcopy and better output when exceptions occur in cleanups are
139 the defining characteristics of this release.
144 * New matcher "Annotate" that adds a simple string message to another matcher,
145 much like the option 'message' parameter to standard library assertFoo
148 * New matchers "Not" and "MatchesAll". "Not" will invert another matcher, and
149 "MatchesAll" that needs a successful match for all of its arguments.
151 * On Python 2.4, where types.FunctionType cannot be deepcopied, testtools will
152 now monkeypatch copy._deepcopy_dispatch using the same trivial patch that
153 added such support to Python 2.5. The monkey patch is triggered by the
154 absence of FunctionType from the dispatch dict rather than a version check.
157 * On windows the test 'test_now_datetime_now' should now work reliably.
159 * TestCase.getUniqueInteger and TestCase.getUniqueString now have docstrings.
161 * TestCase.getUniqueString now takes an optional prefix parameter, so you can
162 now use it in circumstances that forbid strings with '.'s, and such like.
164 * testtools.testcase.clone_test_with_new_id now uses copy.copy, rather than
165 copy.deepcopy. Tests that need a deeper copy should use the copy protocol to
166 control how they are copied. Bug #498869.
168 * The backtrace test result output tests should now pass on windows and other
169 systems where os.sep is not '/'.
171 * When a cleanUp or tearDown exception occurs, it is now accumulated as a new
172 traceback in the test details, rather than as a separate call to addError /
173 addException. This makes testtools work better with most TestResult objects
174 and fixes bug #335816.
180 Python 3 support, more matchers and better consistency with Python 2.7 --
181 you'd think that would be enough for a point release. Well, we here on the
182 testtools project think that you deserve more.
184 We've added a hook so that user code can be called just-in-time whenever there
185 is an exception, and we've also factored out the "run" logic of test cases so
186 that new outcomes can be added without fiddling with the actual flow of logic.
188 It might sound like small potatoes, but it's changes like these that will
189 bring about the end of test frameworks.
195 * A failure in setUp and tearDown now report as failures not as errors.
197 * Cleanups now run after tearDown to be consistent with Python 2.7's cleanup
200 * ExtendedToOriginalDecorator now passes unrecognised attributes through
201 to the decorated result object, permitting other extensions to the
202 TestCase -> TestResult protocol to work.
204 * It is now possible to trigger code just-in-time after an exception causes
205 a test outcome such as failure or skip. See the testtools MANUAL or
206 ``pydoc testtools.TestCase.addOnException``. (bug #469092)
208 * New matcher Equals which performs a simple equality test.
210 * New matcher MatchesAny which looks for a match of any of its arguments.
212 * TestCase no longer breaks if a TestSkipped exception is raised with no
215 * TestCase.run now clones test cases before they are run and runs the clone.
216 This reduces memory footprint in large test runs - state accumulated on
217 test objects during their setup and execution gets freed when test case
218 has finished running unless the TestResult object keeps a reference.
219 NOTE: As test cloning uses deepcopy, this can potentially interfere if
220 a test suite has shared state (such as the testscenarios or testresources
221 projects use). Use the __deepcopy__ hook to control the copying of such
222 objects so that the shared references stay shared.
224 * Testtools now accepts contributions without copyright assignment under some
225 circumstances. See HACKING for details.
227 * Testtools now provides a convenient way to run a test suite using the
228 testtools result object: python -m testtools.run testspec [testspec...].
230 * Testtools now works on Python 3, thanks to Benjamin Peterson.
232 * Test execution now uses a separate class, testtools.RunTest to run single
233 tests. This can be customised and extended in a more consistent fashion than
234 the previous run method idiom. See pydoc for more information.
236 * The test doubles that testtools itself uses are now available as part of
237 the testtools API in testtols.testresult.doubles.
239 * TracebackContent now sets utf8 as the charset encoding, rather than not
240 setting one and encoding with the default encoder.
242 * With python2.7 testtools.TestSkipped will be the unittest.case.SkipTest
243 exception class making skips compatible with code that manually raises the
244 standard library exception. (bug #490109)
249 * TestCase.getUniqueInteger is now implemented using itertools.count. Thanks
250 to Benjamin Peterson for the patch. (bug #490111)
256 The new matcher API introduced in 0.9.0 had a small flaw where the matchee
257 would be evaluated twice to get a description of the mismatch. This could lead
258 to bugs if the act of matching caused side effects to occur in the matchee.
259 Since having such side effects isn't desirable, we have changed the API now
260 before it has become widespread.
265 * Matcher API changed to avoid evaluating matchee twice. Please consult
266 the API documentation.
268 * TestCase.getUniqueString now uses the test id, not the test method name,
269 which works nicer with parameterised tests.
274 * Python2.4 is now supported again.
280 This release of testtools is perhaps the most interesting and exciting one
281 it's ever had. We've continued in bringing together the best practices of unit
282 testing from across a raft of different Python projects, but we've also
283 extended our mission to incorporating unit testing concepts from other
284 languages and from our own research, led by Robert Collins.
286 We now support skipping and expected failures. We'll make sure that you
287 up-call setUp and tearDown, avoiding unexpected testing weirdnesses. We're
288 now compatible with Python 2.5, 2.6 and 2.7 unittest library.
290 All in all, if you are serious about unit testing and want to get the best
291 thinking from the whole Python community, you should get this release.
296 * A new TestResult API has been added for attaching details to test outcomes.
297 This API is currently experimental, but is being prepared with the intent
298 of becoming an upstream Python API. For more details see pydoc
299 testtools.TestResult and the TestCase addDetail / getDetails methods.
301 * assertThat has been added to TestCase. This new assertion supports
302 a hamcrest-inspired matching protocol. See pydoc testtools.Matcher for
303 details about writing matchers, and testtools.matchers for the included
304 matchers. See http://code.google.com/p/hamcrest/.
306 * Compatible with Python 2.6 and Python 2.7
308 * Failing to upcall in setUp or tearDown will now cause a test failure.
309 While the base methods do nothing, failing to upcall is usually a problem
310 in deeper hierarchies, and checking that the root method is called is a
311 simple way to catch this common bug.
313 * New TestResult decorator ExtendedToOriginalDecorator which handles
314 downgrading extended API calls like addSkip to older result objects that
315 do not support them. This is used internally to make testtools simpler but
316 can also be used to simplify other code built on or for use with testtools.
318 * New TextTestResult supporting the extended APIs that testtools provides.
320 * Nose will no longer find 'runTest' tests in classes derived from
321 testtools.testcase.TestCase (bug #312257).
323 * Supports the Python 2.7/3.1 addUnexpectedSuccess and addExpectedFailure
324 TestResult methods, with a support function 'knownFailure' to let tests
325 trigger these outcomes.
327 * When using the skip feature with TestResult objects that do not support it
328 a test success will now be reported. Previously an error was reported but
329 production experience has shown that this is too disruptive for projects that
330 are using skips: they cannot get a clean run on down-level result objects.
