4 Changes and improvements to testtools_, grouped by release.
9 A new sort of TestResult, the StreamResult has been added, as a prototype for
10 a revised standard library test result API. Expect this API to change.
11 Although we will try to preserve compatibility for early adopters, it is
12 experimental and we might need to break it.
17 * ``ConcurrentTestSuite`` was silently eating exceptions that propagate from
18 the test.run(result) method call. Ignoring them is fine in a normal test
19 runner, but when they happen in a different thread, the thread that called
20 suite.run() is not in the stack anymore, and the exceptions are lost. We now
21 create a synthetic test recording any such exception.
22 (Robert Collins, #1130429)
24 * Fixed SyntaxError raised in ``_compat2x.py`` when installing via Python 3.
27 * New class ``StreamResult`` which defines the API for the new result type.
30 * New support class ``ConcurrentStreamTestSuite`` for convenient construction
31 and utilisation of ``StreamToQueue`` objects. (Robert Collins)
33 * New support class ``CopyStreamResult`` which forwards events onto multiple
34 ``StreamResult`` objects (each of which receives all the events).
37 * New support class ``StreamSummary`` which summarises a ``StreamResult``
38 stream compatibly with ``TestResult`` code. (Robert Collins)
40 * New support class ``StreamTagger`` which adds or removes tags from
41 ``StreamResult`` events. (RobertCollins)
43 * New support class ``StreamToDict`` which converts a ``StreamResult`` to a
44 series of dicts describing a test. Useful for writing trivial stream
45 analysers. (Robert Collins)
47 * New support class ``TestControl`` which permits cancelling an in-progress
50 * New support class ``StreamFailFast`` which calls a ``TestControl`` instance
51 to abort the test run when a failure is detected. (Robert Collins)
53 * New support class ``ExtendedToStreamDecorator`` which translates both regular
54 unittest TestResult API calls and the ExtendedTestResult API which testtools
55 has supported into the StreamResult API. ExtendedToStreamDecorator also
56 forwards calls made in the StreamResult API, permitting it to be used
57 anywhere a StreamResult is used. Key TestResult query methods like
58 wasSuccessful and shouldStop are synchronised with the StreamResult API
59 calls, but the detailed statistics like the list of errors are not - a
60 separate consumer will be created to support that.
63 * New support class ``StreamToExtendedDecorator`` which translates
64 ``StreamResult`` API calls into ``ExtendedTestResult`` (or any older
65 ``TestResult``) calls. This permits using un-migrated result objects with
66 new runners / tests. (Robert Collins)
68 * New support class ``StreamToQueue`` for sending messages to one
69 ``StreamResult`` from multiple threads. (Robert Collins)
71 * New support class ``TimestampingStreamResult`` which adds a timestamp to
72 events with no timestamp. (Robert Collins)
74 * New ``TestCase`` decorator ``DecorateTestCaseResult`` that adapts the
75 ``TestResult`` or ``StreamResult`` a case will be run with, for ensuring that
76 a particular result object is used even if the runner running the test doesn't
77 know to use it. (Robert Collins)
79 * New test support class ``testtools.testresult.doubles.StreamResult``, which
80 captures all the StreamResult events. (Robert Collins)
82 * ``PlaceHolder`` can now hold tags, and applies them before, and removes them
83 after, the test. (Robert Collins)
85 * ``PlaceHolder`` can now hold timestamps, and applies them before the test and
86 then before the outcome. (Robert Collins)
88 * The error message for setUp and tearDown upcall errors was broken on Python
89 3.4. (Monty Taylor, Robert Collins, #1140688)
91 * The repr of object() on pypy includes the object id, which was breaking a
92 test that accidentally depended on the CPython repr for object().
98 A simple bug fix, and better error messages when you don't up-call.
103 * ``testtools.content_type.ContentType`` incorrectly used ',' rather than ';'
104 to separate parameters. (Robert Collins)
109 * ``testtools.compat.unicode_output_stream`` was wrapping a stream encoder
110 around ``io.StringIO`` and ``io.TextIOWrapper`` objects, which was incorrect.
113 * Report the name of the source file for setUp and tearDown upcall errors.
119 Testtools has moved VCS - https://github.com/testing-cabal/testtools/ is
120 the new home. Bug tracking is still on Launchpad, and releases are on Pypi.
122 We made this change to take advantage of the richer ecosystem of tools around
123 Git, and to lower the barrier for new contributors.
128 * New ``testtools.testcase.attr`` and ``testtools.testcase.WithAttributes``
129 helpers allow marking up test case methods with simple labels. This permits
130 filtering tests with more granularity than organising them into modules and
131 test classes. (Robert Collins)
139 * New matcher ``HasLength`` for matching the length of a collection.
142 * New matcher ``MatchesPredicateWithParams`` make it still easier to create
143 ad hoc matchers. (Robert Collins)
145 * We have a simpler release process in future - see doc/hacking.rst.
151 Brown paper bag fix: failed to document the need for setup to be able to use
152 extras. Compounded by pip not supporting setup_requires.
157 * setup.py now can generate egg_info even if extras is not available.
158 Also lists extras in setup_requires for easy_install.
159 (Robert Collins, #1102464)
167 * ``python -m testtools.run --load-list`` will now preserve any custom suites
168 (such as ``testtools.FixtureSuite`` or ``testresources.OptimisingTestSuite``)
169 rather than flattening them.
170 (Robert Collins, #827175)
172 * Testtools now depends on extras, a small library split out from it to contain
173 generally useful non-testing facilities. Since extras has been around for a
174 couple of testtools releases now, we're making this into a hard dependency of
175 testtools. (Robert Collins)
177 * Testtools now uses setuptools rather than distutils so that we can document
178 the extras dependency. (Robert Collins)
183 * Testtools will no longer override test code registered details called
184 'traceback' when reporting caught exceptions from test code.
185 (Robert Collins, #812793)
193 * ``testtools.run discover`` will now sort the tests it discovered. This is a
194 workaround for http://bugs.python.org/issue16709. Non-standard test suites
195 are preserved, and their ``sort_tests()`` method called (if they have such an
196 attribute). ``testtools.testsuite.sorted_tests(suite, True)`` can be used by
197 such suites to do a local sort. (Robert Collins, #1091512)
199 * ``ThreadsafeForwardingResult`` now defines a stub ``progress`` method, which
200 fixes ``testr run`` of streams containing progress markers (by discarding the
201 progress data). (Robert Collins, #1019165)
209 * ``run.TestToolsTestRunner`` now accepts the verbosity, buffer and failfast
210 arguments the upstream python TestProgram code wants to give it, making it
211 possible to support them in a compatible fashion. (Robert Collins)
216 * ``testtools.run`` now supports the ``-f`` or ``--failfast`` parameter.
217 Previously it was advertised in the help but ignored.
218 (Robert Collins, #1090582)
220 * ``AnyMatch`` added, a new matcher that matches when any item in a collection
221 matches the given matcher. (Jonathan Lange)
223 * Spelling corrections to documentation. (Vincent Ladeuil)
225 * ``TestProgram`` now has a sane default for its ``testRunner`` argument.
228 * The test suite passes on Python 3 again. (Robert Collins)
236 * ``content_from_file`` and ``content_from_stream`` now accept seek_offset and
237 seek_whence parameters allowing them to be used to grab less than the full
238 stream, or to be used with StringIO streams. (Robert Collins, #1088693)
246 * ``DirContains`` correctly exposed, after being accidentally hidden in the
247 great matcher re-organization of 0.9.17. (Jonathan Lange)
253 Three new matchers that'll rock your world.
258 * New, powerful matchers that match items in a dictionary:
260 - ``MatchesDict``, match every key in a dictionary with a key in a
261 dictionary of matchers. For when the set of expected keys is equal to the
262 set of observed keys.
264 - ``ContainsDict``, every key in a dictionary of matchers must be
265 found in a dictionary, and the values for those keys must match. For when
266 the set of expected keys is a subset of the set of observed keys.
268 - ``ContainedByDict``, every key in a dictionary must be found in
269 a dictionary of matchers. For when the set of expected keys is a superset
270 of the set of observed keys.
272 The names are a little confusing, sorry. We're still trying to figure out
273 how to present the concept in the simplest way possible.
279 How embarrassing! Three releases in two days.
281 We've worked out the kinks and have confirmation from our downstreams that
282 this is all good. Should be the last release for a little while. Please
283 ignore 0.9.18 and 0.9.17.
288 * Include the matcher tests in the release, allowing the tests to run and
289 pass from the release tarball. (Jonathan Lange)
291 * Fix cosmetic test failures in Python 3.3, introduced during release 0.9.17.
298 Due to an oversight, release 0.9.18 did not contain the new
299 ``testtools.matchers`` package and was thus completely broken. This release
300 corrects that, returning us all to normality.
305 This release brings better discover support and Python3.x improvements. There
306 are still some test failures on Python3.3 but they are cosmetic - the library
307 is as usable there as on any other Python 3 release.
312 * The ``testtools.matchers`` package has been split up. No change to the
313 public interface. (Jonathan Lange)
318 * ``python -m testtools.run discover . --list`` now works. (Robert Collins)
320 * Correctly handling of bytes vs text in JSON content type. (Martin [gz])
326 Some new matchers and a new content helper for JSON content.
328 This is the first release of testtools to drop support for Python 2.4 and 2.5.
329 If you need support for either of those versions, please use testtools 0.9.15.
334 * New content helper, ``json_content`` (Jonathan Lange)
338 * ``ContainsAll`` for asserting one thing is a subset of another
341 * ``SameMembers`` for asserting two iterators have the same members.
344 * Reraising of exceptions in Python 3 is more reliable. (Martin [gz])
350 This is the last release to support Python2.4 and 2.5. It brings in a slew of
351 improvements to test tagging and concurrency, making running large test suites
352 with partitioned workers more reliable and easier to reproduce exact test
353 ordering in a given worker. See our sister project ``testrepository`` for a
354 test runner that uses these features.
359 * ``PlaceHolder`` and ``ErrorHolder`` now support being given result details.
362 * ``ErrorHolder`` is now just a function - all the logic is in ``PlaceHolder``.
365 * ``TestResult`` and all other ``TestResult``-like objects in testtools
366 distinguish between global tags and test-local tags, as per the subunit
367 specification. (Jonathan Lange)
369 * This is the **last** release of testtools that supports Python 2.4 or 2.5.
370 These releases are no longer supported by the Python community and do not
371 receive security updates. If this affects you, you will need to either
372 stay on this release or perform your own backports.
373 (Jonathan Lange, Robert Collins)
375 * ``ThreadsafeForwardingResult`` now forwards global tags as test-local tags,
376 making reasoning about the correctness of the multiplexed stream simpler.
377 This preserves the semantic value (what tags apply to a given test) while
378 consuming less stream size (as no negative-tag statement is needed).
379 (Robert Collins, Gary Poster, #986434)
384 * API documentation corrections. (Raphaël Badin)
386 * ``ConcurrentTestSuite`` now takes an optional ``wrap_result`` parameter
387 that can be used to wrap the ``ThreadsafeForwardingResults`` created by
388 the suite. (Jonathan Lange)
390 * ``Tagger`` added. It's a new ``TestResult`` that tags all tests sent to
391 it with a particular set of tags. (Jonathan Lange)
393 * ``testresultdecorator`` brought over from subunit. (Jonathan Lange)
395 * All ``TestResult`` wrappers now correctly forward ``current_tags`` from
396 their wrapped results, meaning that ``current_tags`` can always be relied
397 upon to return the currently active tags on a test result.
399 * ``TestByTestResult``, a ``TestResult`` that calls a method once per test,
400 added. (Jonathan Lange)
402 * ``ThreadsafeForwardingResult`` correctly forwards ``tags()`` calls where
403 only one of ``new_tags`` or ``gone_tags`` are specified.
404 (Jonathan Lange, #980263)
406 * ``ThreadsafeForwardingResult`` no longer leaks local tags from one test
407 into all future tests run. (Jonathan Lange, #985613)
409 * ``ThreadsafeForwardingResult`` has many, many more tests. (Jonathan Lange)
415 Our sister project, `subunit <https://launchpad.net/subunit>`_, was using a
416 private API that was deleted in the 0.9.13 release. This release restores
417 that API in order to smooth out the upgrade path.
419 If you don't use subunit, then this release won't matter very much to you.
425 Plenty of new matchers and quite a few critical bug fixes (especially to do
426 with stack traces from failed assertions). A net win for all.
431 * ``MatchesAll`` now takes an ``first_only`` keyword argument that changes how
432 mismatches are displayed. If you were previously passing matchers to
433 ``MatchesAll`` with keyword arguments, then this change might affect your
434 test results. (Jonathan Lange)
439 * Actually hide all of the testtools stack for assertion failures. The
440 previous release promised clean stack, but now we actually provide it.
441 (Jonathan Lange, #854769)
443 * ``assertRaises`` now includes the ``repr`` of the callable that failed to raise
444 properly. (Jonathan Lange, #881052)
446 * Asynchronous tests no longer hang when run with trial.
447 (Jonathan Lange, #926189)
449 * ``Content`` objects now have an ``as_text`` method to convert their contents
450 to Unicode text. (Jonathan Lange)
452 * Failed equality assertions now line up. (Jonathan Lange, #879339)
454 * ``FullStackRunTest`` no longer aborts the test run if a test raises an
455 error. (Jonathan Lange)
457 * ``MatchesAll`` and ``MatchesListwise`` both take a ``first_only`` keyword
458 argument. If True, they will report only on the first mismatch they find,
459 and not continue looking for other possible mismatches.
462 * New helper, ``Nullary`` that turns callables with arguments into ones that
463 don't take arguments. (Jonathan Lange)
467 * ``DirContains`` matches the contents of a directory.
468 (Jonathan Lange, James Westby)
470 * ``DirExists`` matches if a directory exists.
471 (Jonathan Lange, James Westby)
473 * ``FileContains`` matches the contents of a file.
474 (Jonathan Lange, James Westby)
476 * ``FileExists`` matches if a file exists.
477 (Jonathan Lange, James Westby)
479 * ``HasPermissions`` matches the permissions of a file. (Jonathan Lange)
481 * ``MatchesPredicate`` matches if a predicate is true. (Jonathan Lange)
483 * ``PathExists`` matches if a path exists. (Jonathan Lange, James Westby)
485 * ``SamePath`` matches if two paths are the same. (Jonathan Lange)
487 * ``TarballContains`` matches the contents of a tarball. (Jonathan Lange)
489 * ``MultiTestResult`` supports the ``tags`` method.
490 (Graham Binns, Francesco Banconi, #914279)
492 * ``ThreadsafeForwardingResult`` supports the ``tags`` method.
493 (Graham Binns, Francesco Banconi, #914279)
495 * ``ThreadsafeForwardingResult`` no longer includes semaphore acquisition time
496 in the test duration (for implicitly timed test runs).
497 (Robert Collins, #914362)
502 This is a very big release. We've made huge improvements on three fronts:
503 1. Test failures are way nicer and easier to read
504 2. Matchers and ``assertThat`` are much more convenient to use
505 3. Correct handling of extended unicode characters
507 We've trimmed off the fat from the stack trace you get when tests fail, we've
508 cut out the bits of error messages that just didn't help, we've made it easier
509 to annotate mismatch failures, to compare complex objects and to match raised
512 Testing code was never this fun.
517 * ``AfterPreproccessing`` renamed to ``AfterPreprocessing``, which is a more
518 correct spelling. Old name preserved for backwards compatibility, but is
519 now deprecated. Please stop using it.
520 (Jonathan Lange, #813460)
522 * ``assertThat`` raises ``MismatchError`` instead of
523 ``TestCase.failureException``. ``MismatchError`` is a subclass of
524 ``AssertionError``, so in most cases this change will not matter. However,
525 if ``self.failureException`` has been set to a non-default value, then
526 mismatches will become test errors rather than test failures.
528 * ``gather_details`` takes two dicts, rather than two detailed objects.
529 (Jonathan Lange, #801027)
531 * ``MatchesRegex`` mismatch now says "<value> does not match /<regex>/" rather
532 than "<regex> did not match <value>". The regular expression contains fewer
533 backslashes too. (Jonathan Lange, #818079)
535 * Tests that run with ``AsynchronousDeferredRunTest`` now have the ``reactor``
536 attribute set to the running reactor. (Jonathan Lange, #720749)
541 * All public matchers are now in ``testtools.matchers.__all__``.
542 (Jonathan Lange, #784859)
544 * ``assertThat`` can actually display mismatches and matchers that contain
545 extended unicode characters. (Jonathan Lange, Martin [gz], #804127)
547 * ``assertThat`` output is much less verbose, displaying only what the mismatch
548 tells us to display. Old-style verbose output can be had by passing
549 ``verbose=True`` to assertThat. (Jonathan Lange, #675323, #593190)
551 * ``assertThat`` accepts a message which will be used to annotate the matcher.
552 This can be given as a third parameter or as a keyword parameter.
555 * Automated the Launchpad part of the release process.
556 (Jonathan Lange, #623486)
558 * Correctly display non-ASCII unicode output on terminals that claim to have a
559 unicode encoding. (Martin [gz], #804122)
561 * ``DocTestMatches`` correctly handles unicode output from examples, rather
562 than raising an error. (Martin [gz], #764170)
564 * ``ErrorHolder`` and ``PlaceHolder`` added to docs. (Jonathan Lange, #816597)
566 * ``ExpectedException`` now matches any exception of the given type by
567 default, and also allows specifying a ``Matcher`` rather than a mere regular
568 expression. (Jonathan Lange, #791889)
570 * ``FixtureSuite`` added, allows test suites to run with a given fixture.
573 * Hide testtools's own stack frames when displaying tracebacks, making it
574 easier for test authors to focus on their errors.
575 (Jonathan Lange, Martin [gz], #788974)
577 * Less boilerplate displayed in test failures and errors.
578 (Jonathan Lange, #660852)
580 * ``MatchesException`` now allows you to match exceptions against any matcher,
581 rather than just regular expressions. (Jonathan Lange, #791889)
583 * ``MatchesException`` now permits a tuple of types rather than a single type
584 (when using the type matching mode). (Robert Collins)
586 * ``MatchesStructure.byEquality`` added to make the common case of matching
587 many attributes by equality much easier. ``MatchesStructure.byMatcher``
588 added in case folk want to match by things other than equality.
591 * New convenience assertions, ``assertIsNone`` and ``assertIsNotNone``.
596 * ``AllMatch`` matches many values against a single matcher.
597 (Jonathan Lange, #615108)
599 * ``Contains``. (Robert Collins)
601 * ``GreaterThan``. (Christian Kampka)
603 * New helper, ``safe_hasattr`` added. (Jonathan Lange)
605 * ``reraise`` added to ``testtools.compat``. (Jonathan Lange)
611 This release brings consistent use of super for better compatibility with
612 multiple inheritance, fixed Python3 support, improvements in fixture and mather
613 outputs and a compat helper for testing libraries that deal with bytestrings.
618 * ``TestCase`` now uses super to call base ``unittest.TestCase`` constructor,
619 ``setUp`` and ``tearDown``. (Tim Cole, #771508)
621 * If, when calling ``useFixture`` an error occurs during fixture set up, we
622 still attempt to gather details from the fixture. (Gavin Panella)
628 * Additional compat helper for ``BytesIO`` for libraries that build on
629 testtools and are working on Python 3 porting. (Robert Collins)
631 * Corrected documentation for ``MatchesStructure`` in the test authors
632 document. (Jonathan Lange)
634 * ``LessThan`` error message now says something that is logically correct.
635 (Gavin Panella, #762008)
637 * Multiple details from a single fixture are now kept separate, rather than
638 being mooshed together. (Gavin Panella, #788182)
640 * Python 3 support now back in action. (Martin [gz], #688729)
642 * ``try_import`` and ``try_imports`` have a callback that is called whenever
643 they fail to import a module. (Martin Pool)
649 The last release of testtools could not be easy_installed. This is considered
650 severe enough for a re-release.
655 * Include ``doc/`` in the source distribution, making testtools installable
656 from PyPI again (Tres Seaver, #757439)
662 Many, many new matchers, vastly expanded documentation, stacks of bug fixes,
663 better unittest2 integration. If you've ever wanted to try out testtools but
664 been afraid to do so, this is the release to try.
670 * The timestamps generated by ``TestResult`` objects when no timing data has
671 been received are now datetime-with-timezone, which allows them to be
672 sensibly serialised and transported. (Robert Collins, #692297)
677 * ``AnnotatedMismatch`` now correctly returns details.
678 (Jonathan Lange, #724691)
680 * distutils integration for the testtools test runner. Can now use it for
681 'python setup.py test'. (Christian Kampka, #693773)
683 * ``EndsWith`` and ``KeysEqual`` now in testtools.matchers.__all__.
684 (Jonathan Lange, #692158)
686 * ``MatchesException`` extended to support a regular expression check against
687 the str() of a raised exception. (Jonathan Lange)
689 * ``MultiTestResult`` now forwards the ``time`` API. (Robert Collins, #692294)
691 * ``MultiTestResult`` now documented in the manual. (Jonathan Lange, #661116)
693 * New content helpers ``content_from_file``, ``content_from_stream`` and
694 ``attach_file`` make it easier to attach file-like objects to a
695 test. (Jonathan Lange, Robert Collins, #694126)
697 * New ``ExpectedException`` context manager to help write tests against things
698 that are expected to raise exceptions. (Aaron Bentley)
702 * ``MatchesListwise`` matches an iterable of matchers against an iterable
703 of values. (Michael Hudson-Doyle)
705 * ``MatchesRegex`` matches a string against a regular expression.
706 (Michael Hudson-Doyle)
708 * ``MatchesStructure`` matches attributes of an object against given
709 matchers. (Michael Hudson-Doyle)
711 * ``AfterPreproccessing`` matches values against a matcher after passing them
712 through a callable. (Michael Hudson-Doyle)
714 * ``MatchesSetwise`` matches an iterable of matchers against an iterable of
715 values, without regard to order. (Michael Hudson-Doyle)
717 * ``setup.py`` can now build a snapshot when Bazaar is installed but the tree
718 is not a Bazaar tree. (Jelmer Vernooij)
720 * Support for running tests using distutils (Christian Kampka, #726539)
722 * Vastly improved and extended documentation. (Jonathan Lange)
724 * Use unittest2 exception classes if available. (Jelmer Vernooij)
730 In this release we bring some very interesting improvements:
732 * new matchers for exceptions, sets, lists, dicts and more.
734 * experimental (works but the contract isn't supported) twisted reactor
737 * The built in runner can now list tests and filter tests (the -l and
738 --load-list options).
743 * addUnexpectedSuccess is translated to addFailure for test results that don't
744 know about addUnexpectedSuccess. Further, it fails the entire result for
745 all testtools TestResults (i.e. wasSuccessful() returns False after
746 addUnexpectedSuccess has been called). Note that when using a delegating
747 result such as ThreadsafeForwardingResult, MultiTestResult or
748 ExtendedToOriginalDecorator then the behaviour of addUnexpectedSuccess is
749 determined by the delegated to result(s).
750 (Jonathan Lange, Robert Collins, #654474, #683332)
752 * startTestRun will reset any errors on the result. That is, wasSuccessful()
753 will always return True immediately after startTestRun() is called. This
754 only applies to delegated test results (ThreadsafeForwardingResult,
755 MultiTestResult and ExtendedToOriginalDecorator) if the delegated to result
756 is a testtools test result - we cannot reliably reset the state of unknown
757 test result class instances. (Jonathan Lange, Robert Collins, #683332)
759 * Responsibility for running test cleanups has been moved to ``RunTest``.
760 This change does not affect public APIs and can be safely ignored by test
761 authors. (Jonathan Lange, #662647)
768 * ``EndsWith`` which complements the existing ``StartsWith`` matcher.
769 (Jonathan Lange, #669165)
771 * ``MatchesException`` matches an exception class and parameters. (Robert
774 * ``KeysEqual`` matches a dictionary with particular keys. (Jonathan Lange)
776 * ``assertIsInstance`` supports a custom error message to be supplied, which
777 is necessary when using ``assertDictEqual`` on Python 2.7 with a
778 ``testtools.TestCase`` base class. (Jelmer Vernooij)
780 * Experimental support for running tests that return Deferreds.
781 (Jonathan Lange, Martin [gz])
783 * Provide a per-test decorator, run_test_with, to specify which RunTest
784 object to use for a given test. (Jonathan Lange, #657780)
786 * Fix the runTest parameter of TestCase to actually work, rather than raising
787 a TypeError. (Jonathan Lange, #657760)
789 * Non-release snapshots of testtools will now work with buildout.
790 (Jonathan Lange, #613734)
792 * Malformed SyntaxErrors no longer blow up the test suite. (Martin [gz])
794 * ``MismatchesAll.describe`` no longer appends a trailing newline.
795 (Michael Hudson-Doyle, #686790)
797 * New helpers for conditionally importing modules, ``try_import`` and
798 ``try_imports``. (Jonathan Lange)
800 * ``Raises`` added to the ``testtools.matchers`` module - matches if the
801 supplied callable raises, and delegates to an optional matcher for validation
802 of the exception. (Robert Collins)
804 * ``raises`` added to the ``testtools.matchers`` module - matches if the
805 supplied callable raises and delegates to ``MatchesException`` to validate
806 the exception. (Jonathan Lange)
808 * Tests will now pass on Python 2.6.4 : an ``Exception`` change made only in
809 2.6.4 and reverted in Python 2.6.5 was causing test failures on that version.
810 (Martin [gz], #689858).
812 * ``testtools.TestCase.useFixture`` has been added to glue with fixtures nicely.
815 * ``testtools.run`` now supports ``-l`` to list tests rather than executing
816 them. This is useful for integration with external test analysis/processing
817 tools like subunit and testrepository. (Robert Collins)
819 * ``testtools.run`` now supports ``--load-list``, which takes a file containing
820 test ids, one per line, and intersects those ids with the tests found. This
821 allows fine grained control of what tests are run even when the tests cannot
822 be named as objects to import (e.g. due to test parameterisation via
823 testscenarios). (Robert Collins)
825 * Update documentation to say how to use testtools.run() on Python 2.4.
826 (Jonathan Lange, #501174)
828 * ``text_content`` conveniently converts a Python string to a Content object.
829 (Jonathan Lange, James Westby)
836 Lots of little cleanups in this release; many small improvements to make your
837 testing life more pleasant.
842 * Cleanups can raise ``testtools.MultipleExceptions`` if they have multiple
843 exceptions to report. For instance, a cleanup which is itself responsible for
844 running several different internal cleanup routines might use this.
846 * Code duplication between assertEqual and the matcher Equals has been removed.
848 * In normal circumstances, a TestCase will no longer share details with clones
849 of itself. (Andrew Bennetts, bug #637725)
851 * Less exception object cycles are generated (reduces peak memory use between
852 garbage collection). (Martin [gz])
854 * New matchers 'DoesNotStartWith' and 'StartsWith' contributed by Canonical
855 from the Launchpad project. Written by James Westby.
857 * Timestamps as produced by subunit protocol clients are now forwarded in the
858 ThreadsafeForwardingResult so correct test durations can be reported.
859 (Martin [gz], Robert Collins, #625594)
861 * With unittest from Python 2.7 skipped tests will now show only the reason
862 rather than a serialisation of all details. (Martin [gz], #625583)
864 * The testtools release process is now a little better documented and a little
865 smoother. (Jonathan Lange, #623483, #623487)
871 Nothing major in this release, just enough small bits and pieces to make it
872 useful enough to upgrade to.
874 In particular, a serious bug in assertThat() has been fixed, it's easier to
875 write Matchers, there's a TestCase.patch() method for those inevitable monkey
876 patches and TestCase.assertEqual gives slightly nicer errors.
881 * 'TestCase.assertEqual' now formats errors a little more nicely, in the
884 * Added `PlaceHolder` and `ErrorHolder`, TestCase-like objects that can be
885 used to add results to a `TestResult`.
887 * 'Mismatch' now takes optional description and details parameters, so
888 custom Matchers aren't compelled to make their own subclass.
890 * jml added a built-in UTF8_TEXT ContentType to make it slightly easier to
891 add details to test results. See bug #520044.
893 * Fix a bug in our built-in matchers where assertThat would blow up if any
894 of them failed. All built-in mismatch objects now provide get_details().
896 * New 'Is' matcher, which lets you assert that a thing is identical to
899 * New 'LessThan' matcher which lets you assert that a thing is less than
902 * TestCase now has a 'patch()' method to make it easier to monkey-patching
903 objects in tests. See the manual for more information. Fixes bug #310770.
905 * MultiTestResult methods now pass back return values from the results it
911 This release fixes some obscure traceback formatting issues that probably
912 weren't affecting you but were certainly breaking our own test suite.
917 * Jamu Kakar has updated classes in testtools.matchers and testtools.runtest
918 to be new-style classes, fixing bug #611273.
923 * Martin[gz] fixed traceback handling to handle cases where extract_tb returns
924 a source line of None. Fixes bug #611307.
926 * Martin[gz] fixed an unicode issue that was causing the tests to fail,
929 * testtools now handles string exceptions (although why would you want to use
930 them?) and formats their tracebacks correctly. Thanks to Martin[gz] for
936 This release overhauls the traceback formatting layer to deal with Python 2
937 line numbers and traceback objects often being local user encoded strings
938 rather than unicode objects. Test discovery has also been added and Python 3.1
939 is also supported. Finally, the Mismatch protocol has been extended to let
940 Matchers collaborate with tests in supplying detailed data about failures.
945 * testtools.utils has been renamed to testtools.compat. Importing
946 testtools.utils will now generate a deprecation warning.
951 * Add machinery for Python 2 to create unicode tracebacks like those used by
952 Python 3. This means testtools no longer throws on encountering non-ascii
953 filenames, source lines, or exception strings when displaying test results.
954 Largely contributed by Martin[gz] with some tweaks from Robert Collins.
956 * James Westby has supplied test discovery support using the Python 2.7
957 TestRunner in testtools.run. This requires the 'discover' module. This
960 * Python 3.1 is now supported, thanks to Martin[gz] for a partial patch.
961 This fixes bug #592375.
963 * TestCase.addCleanup has had its docstring corrected about when cleanups run.
965 * TestCase.skip is now deprecated in favour of TestCase.skipTest, which is the
966 Python2.7 spelling for skip. This closes bug #560436.
968 * Tests work on IronPython patch from Martin[gz] applied.
970 * Thanks to a patch from James Westby testtools.matchers.Mismatch can now
971 supply a get_details method, which assertThat will query to provide
972 additional attachments. This can be used to provide additional detail
973 about the mismatch that doesn't suite being included in describe(). For
974 instance, if the match process was complex, a log of the process could be
975 included, permitting debugging.
977 * testtools.testresults.real._StringException will now answer __str__ if its
978 value is unicode by encoding with UTF8, and vice versa to answer __unicode__.
979 This permits subunit decoded exceptions to contain unicode and still format
985 More matchers, Python 2.4 support, faster test cloning by switching to copy
986 rather than deepcopy and better output when exceptions occur in cleanups are
987 the defining characteristics of this release.
992 * New matcher "Annotate" that adds a simple string message to another matcher,
993 much like the option 'message' parameter to standard library assertFoo
996 * New matchers "Not" and "MatchesAll". "Not" will invert another matcher, and
997 "MatchesAll" that needs a successful match for all of its arguments.
999 * On Python 2.4, where types.FunctionType cannot be deepcopied, testtools will
1000 now monkeypatch copy._deepcopy_dispatch using the same trivial patch that
1001 added such support to Python 2.5. The monkey patch is triggered by the
1002 absence of FunctionType from the dispatch dict rather than a version check.
1005 * On windows the test 'test_now_datetime_now' should now work reliably.
1007 * TestCase.getUniqueInteger and TestCase.getUniqueString now have docstrings.
1009 * TestCase.getUniqueString now takes an optional prefix parameter, so you can
1010 now use it in circumstances that forbid strings with '.'s, and such like.
1012 * testtools.testcase.clone_test_with_new_id now uses copy.copy, rather than
1013 copy.deepcopy. Tests that need a deeper copy should use the copy protocol to
1014 control how they are copied. Bug #498869.
1016 * The backtrace test result output tests should now pass on windows and other
1017 systems where os.sep is not '/'.
1019 * When a cleanUp or tearDown exception occurs, it is now accumulated as a new
1020 traceback in the test details, rather than as a separate call to addError /
1021 addException. This makes testtools work better with most TestResult objects
1022 and fixes bug #335816.
1028 Python 3 support, more matchers and better consistency with Python 2.7 --
1029 you'd think that would be enough for a point release. Well, we here on the
1030 testtools project think that you deserve more.
1032 We've added a hook so that user code can be called just-in-time whenever there
1033 is an exception, and we've also factored out the "run" logic of test cases so
1034 that new outcomes can be added without fiddling with the actual flow of logic.
1036 It might sound like small potatoes, but it's changes like these that will
1037 bring about the end of test frameworks.
1043 * A failure in setUp and tearDown now report as failures not as errors.
1045 * Cleanups now run after tearDown to be consistent with Python 2.7's cleanup
1048 * ExtendedToOriginalDecorator now passes unrecognised attributes through
1049 to the decorated result object, permitting other extensions to the
1050 TestCase -> TestResult protocol to work.
1052 * It is now possible to trigger code just-in-time after an exception causes
1053 a test outcome such as failure or skip. See the testtools MANUAL or
1054 ``pydoc testtools.TestCase.addOnException``. (bug #469092)
1056 * New matcher Equals which performs a simple equality test.
1058 * New matcher MatchesAny which looks for a match of any of its arguments.
1060 * TestCase no longer breaks if a TestSkipped exception is raised with no
1063 * TestCase.run now clones test cases before they are run and runs the clone.
1064 This reduces memory footprint in large test runs - state accumulated on
1065 test objects during their setup and execution gets freed when test case
1066 has finished running unless the TestResult object keeps a reference.
1067 NOTE: As test cloning uses deepcopy, this can potentially interfere if
1068 a test suite has shared state (such as the testscenarios or testresources
1069 projects use). Use the __deepcopy__ hook to control the copying of such
1070 objects so that the shared references stay shared.
1072 * Testtools now accepts contributions without copyright assignment under some
1073 circumstances. See HACKING for details.
1075 * Testtools now provides a convenient way to run a test suite using the
1076 testtools result object: python -m testtools.run testspec [testspec...].
1078 * Testtools now works on Python 3, thanks to Benjamin Peterson.
1080 * Test execution now uses a separate class, testtools.RunTest to run single
1081 tests. This can be customised and extended in a more consistent fashion than
1082 the previous run method idiom. See pydoc for more information.
1084 * The test doubles that testtools itself uses are now available as part of
1085 the testtools API in testtols.testresult.doubles.
1087 * TracebackContent now sets utf8 as the charset encoding, rather than not
1088 setting one and encoding with the default encoder.
1090 * With python2.7 testtools.TestSkipped will be the unittest.case.SkipTest
1091 exception class making skips compatible with code that manually raises the
1092 standard library exception. (bug #490109)
1097 * TestCase.getUniqueInteger is now implemented using itertools.count. Thanks
1098 to Benjamin Peterson for the patch. (bug #490111)
1104 The new matcher API introduced in 0.9.0 had a small flaw where the matchee
1105 would be evaluated twice to get a description of the mismatch. This could lead
1106 to bugs if the act of matching caused side effects to occur in the matchee.
1107 Since having such side effects isn't desirable, we have changed the API now
1108 before it has become widespread.
1113 * Matcher API changed to avoid evaluating matchee twice. Please consult
1114 the API documentation.
1116 * TestCase.getUniqueString now uses the test id, not the test method name,
1117 which works nicer with parameterised tests.
1122 * Python2.4 is now supported again.
1128 This release of testtools is perhaps the most interesting and exciting one
1129 it's ever had. We've continued in bringing together the best practices of unit
1130 testing from across a raft of different Python projects, but we've also
1131 extended our mission to incorporating unit testing concepts from other
1132 languages and from our own research, led by Robert Collins.
1134 We now support skipping and expected failures. We'll make sure that you
1135 up-call setUp and tearDown, avoiding unexpected testing weirdnesses. We're
1136 now compatible with Python 2.5, 2.6 and 2.7 unittest library.
1138 All in all, if you are serious about unit testing and want to get the best
1139 thinking from the whole Python community, you should get this release.
1144 * A new TestResult API has been added for attaching details to test outcomes.
1145 This API is currently experimental, but is being prepared with the intent
1146 of becoming an upstream Python API. For more details see pydoc
1147 testtools.TestResult and the TestCase addDetail / getDetails methods.
1149 * assertThat has been added to TestCase. This new assertion supports
1150 a hamcrest-inspired matching protocol. See pydoc testtools.Matcher for
1151 details about writing matchers, and testtools.matchers for the included
1152 matchers. See http://code.google.com/p/hamcrest/.
1154 * Compatible with Python 2.6 and Python 2.7
1156 * Failing to upcall in setUp or tearDown will now cause a test failure.
1157 While the base methods do nothing, failing to upcall is usually a problem
1158 in deeper hierarchies, and checking that the root method is called is a
1159 simple way to catch this common bug.
1161 * New TestResult decorator ExtendedToOriginalDecorator which handles
1162 downgrading extended API calls like addSkip to older result objects that
1163 do not support them. This is used internally to make testtools simpler but
1164 can also be used to simplify other code built on or for use with testtools.
1166 * New TextTestResult supporting the extended APIs that testtools provides.
1168 * Nose will no longer find 'runTest' tests in classes derived from
1169 testtools.testcase.TestCase (bug #312257).
1171 * Supports the Python 2.7/3.1 addUnexpectedSuccess and addExpectedFailure
1172 TestResult methods, with a support function 'knownFailure' to let tests
1173 trigger these outcomes.
1175 * When using the skip feature with TestResult objects that do not support it
1176 a test success will now be reported. Previously an error was reported but
1177 production experience has shown that this is too disruptive for projects that
1178 are using skips: they cannot get a clean run on down-level result objects.
