• New: Users can now easily access the current cases for each parametrized argument thanks to the new current_cases fixture. A new helper function get_current_cases is also provided, for direct access from a hook. get_current_case_id becomes deprecated in favour of these two. Fixes #195

• Bugfix: Fixed issue where the cache of a lazy_value used for a tuple of parameters (several argnames) was not considering the pytest context and thus was wrongly used across pytest nodes. Fixes #202

• Improved error message when a fixture parametrized with several argnames as once is not able to unpack the parameter values received (non subscriptable object).

• parametrize_plus and fixture_plus are now deprecated in favour of parametrize and fixture, as most users seem to have adopted these names without issues.

• (internal) Replaced the "used" parameter with a dedicated singleton USED

See documentation page for details.

• Legacy v1 API was dropped. Fixes #192

• Unbound case functions in a class (e.g. Foo.bar) can now be directly passed to parametrize_with_cases without instantiating the class, e.g. parametrize_with_cases(cases=Foo.bar). Fixes #159

• Fixed bug with concatenation of marks on cases. Fixes #191

• Fixed an issue where a case transformed into a fixture, with the same name as the fixture it requires, would lead to a pytest fixture recursion.

• Fixtures in case files can now be automatically imported using the experimental @parametrize_with_cases(import_fixtures=True). Fixes #193

See documentation page for details.

• Migrated to Github Actions + nox for CI/CD.

• New helper function get_current_case_id to get the current case id for a given pytest request or item. Fixes #189

• Extended the support of fixture closure modifications to remove and insert(0, f). This in particular solves an issue with pytest-asyncio. Fixes #176

• New filters module providing helper functions has_tag, id_has_prefix, id_has_suffix, id_match_regex to easily create custom filters for use in @parametrize_with_cases(filter=...). PR #184 by @saroad2, (thanks !).

See documentation page for details.

• Fixed fixture 'self' not found issue when @fixture was used to decorate a class method not explicitly depending on request. Fixed #182

See documentation page for details.

• New: from version 3.2 on, if auto_refs=True (default), @parametrize will automatically detect fixture symbols in the list of argvalues, and will create fixture_refs automatically around them so that you don't need to. Fixes #177

• Fixed ordering issue happening on linux targets when several @parametrize are used to decorate the same function. Fixes #180

See documentation page for details.

• Now appending fixtures to the closure once it has been built is supported. This fixes an issue with pytest-asyncio. Fixes #176

• Fixed issue when parametrize_with_cases was used on case functions themselves (nesting/recursion). This was due to a lack of support of the place_as magic pytest attribute. Fixes #179

• Added a warning concerning usage of indirect in parametrize when fixture references are present. See #150

See documentation page for details.

• Fixed issue with Empty id marker leaking to test ids. Fixed #171

See documentation page for details.

• @parametrize_with_cases now by default (cases=AUTO) looks for both file naming patterns test_<name>_cases.py and cases_<name>.py. Removed the AUTO2 constant. Fixed #140

• Nested classes containing case functions are now officially supported (they were, but undocumented). Fixed #160

• Case functions that are staticmethod and classmethod are now supported as well. Fixes #168

See documentation page for details.

• Major refactoring of the way ids and marks are generated and customized in fixture_union, @parametrize and @parametrize_with_cases. Now idstyle has a consistent behaviour across the board, ids and idstyle can work together correctly, @parametrize_with_cases and @parametrize have much better default values for ids, and many others. See documentation for details. Fixed #154

• New public API to manipulate information about a case function: copy_case_info, set_case_id, get_case_id, get_case_marks, get_case_tags, matches_tag_query, is_case_class, is_case_function. See API reference.

• Fixed default behaviour of idgen in @parametrize: it only defaults to AUTO when no fixture_ref are used in the argvalues.

See documentation page for details.

• Fixed AttributeError: 'DoctestItem' object has no attribute '_request' when executing doctests. Fixes #156

See documentation page for details.

• @pytest.mark.usefixtures can be now be used on case functions. Fixes #152.

See documentation page for details.

• lazy_value parameters are now cached by pytest node id only. So plugins can access the value without triggering an extra function call, but a new call is triggered for each pytest node, so as to prevent mutable object leakage across tests. Fixed #149 while ensuring no regression for #143.

• The ids argument of parametrize now accepts a (possibly infinite) generator of ids, e.g. (f"foo{i}" for i in itertools.count()), just as pytest does. This was not always the case, inparticular when parametrizing a @fixture. The ids arguments of fixture_union, param_fixture[s], etc. now also support this pattern. Fixed #148

See documentation page for details.

• Improved description for the glob argument in @parametrize_with_cases. Also made the implementation escape all regex special characters so that they can't be used. Finally a pattern should now match the entire case id (previously, a partial match would work if it was at the beginning of the string). One step towards #147

See documentation page for details.

• is_lazy is now part of public API, and _LazyValue now has a cache mechanism like _LazyTuple. Fixes #143

• @parametrize: custom ids are now correctly taken into account when a single lazy_valueis used for a tuple of parameters. This issue could be seen also with @parametrize_with_cases: idgen does not seem to be taken into account when cases are unpacked into a tuple. Fixes #144.

• Empty case ids are now replaced with '<empty_case_id>' to avoid ambiguous interpretation of test ids. Fixes #142.

See documentation page for details.

• new clone(self, remove_int_base=False) API on LazyValue and LazyTupleItem instances. With this new API, on old pytest < 5.3, other plugins such as pytest-harvest can easily clone the contents from lazy values without having them inherit from int - which was a dirty hack used by pytest-cases to trick pytest to generate acceptable test ids in these old pytest versions. Also improved the LazyValue, LazyTuple and LazyTupleItem object model with equality and repr. Fixes pytest-harvest#43

See documentation page for details.

• Marks set on a case class are now propagated to cases in the class. So you can use for example pytest-pilot more easily ! Fixes #139

See documentation page for details.

• Fixed "Created fixture names are not unique, please report" error when duplicate fixture reference is provided in a pytest.param. Fixes #138.

See documentation page for details.

• Fixed TypeError: _idval() got an unexpected keyword argument 'item' with pytest versions between 3.0.0 and 3.7.4. Fixed #136

See documentation page for details.

• @parametrize_with_cases now supports that argnames is a list or tuple, just as @pytest.mark.parametrize does. PR #132, by @saroad2.

See documentation page for details.

• Now enforcing usage of makefun 1.9.3 or above to avoid issue AttributeError: 'functools.partial' object has no attribute '__module__' mentioned in #128

See documentation page for details.

• Improved documentation to explain why @fixture should be used instead of @pytest.fixture. Fixed #125

• Fixed ValueError: fixture is being applied more than once to the same function when two functions parametrized with the same cases were sitting in the same file. Improved robustness when cases require fixtures, in particular when parametrized test/fixture sits in a class or when several of them sit in a class/module. Fixed #126

See documentation page for details.

• Added missing deprecation warning on @cases_generator. Fixes #124.

• Removed target and tags arguments of @cases_generator (deprecated api anyway) that were added by mistake in version 2.0.0 but never used.

See documentation page for details.

• Added support for pytest items without funcargs. Fixes interoperability with other pytest plugins such as pytest-black or pytest-flake8. Fixes #122

See documentation page for details.

pytest 6 is now supported. Fixes #121

Fixed issue with @parametrize_with_cases when two cases with the same id and both requiring a fixture were to be created. Fixed #117.

Fixture closure engine refactoring:

• When no fixture unions are present, the fixture closure is now identical to the default one in pytest, to avoid issues originating from other plugins fiddling with the closure. Fixes #116

• New SuperClosure class representing the "list" facade on top of the fixture tree (instead of FixtureClosureNode). In addition, this list facade now better handles editing the order of fixtures when possible. Fixes #111.

• Session and Module-scoped fixtures that are not used in all union alternatives are not any more torn town/setup across union alternatives. Fixes #120

See documentation page for details.

• Fixed TypeError with iterable argvalue in standard parametrize. Fixed #115.

See documentation page for details.
