  • Fixed most flake8 errors and updated documentation to use genbadge. Fixes #223

3.6.1 - bugfix - parametrizing a class with @parametrize

  • Fixed ValueError when @parametrize is used to parametrize a class. Also, added a more explicit TypeError when @parametrize is used to parametrize a class and at least a fixture reference is present. Fixed #215.

3.6.0 - unpack_fixtures in classes + current_cases improvements

  • The current_cases fixture now contains case parameters if any. Fixes #214

  • The current_cases fixture entries are now instances of namedtuple.

  • New in_cls argument in unpack_fixtures so that it can be used inside classes. Fixes #201

  • Fixed minor issue where empty entries could be present in currentcases. Fixes #213

3.5.2 - bugfix with the currentcases fixture

  • Fixed issues where the currentcases fixture would not return the correct case function. Fixed #212

3.5.1 - python 3.10 compatibility + improved error message

  • Fixed error message related to misuse of fixture_ref. Fixes #209
  • Fixed import error with python 3.10. Fixes #207

3.5.0 - New current_cases fixture and get_current_cases function + Fixes

  • 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

3.4.6 - Increased compatibility with other plugins

  • LazyValue, LazyTuple and LazyTupleItem are now hashable. This increases compatibility with plugins hashing the parameter values, such as pytest-steps. See pytest-steps#41 . Fixes #199

3.4.5 - Bugfix

  • Fixed bug when a test module containing @parametrize_with_cases was executed outside of pytest, typically through its __main__. Fixes #198

3.4.4 - Bugfix

  • Fixed issue when @parametrize_with_cases was used on a fixture in a conftest.py. Fixes #196

3.4.3 - Technical release - Zenodo

Technical release to check that Zenodo metadata is now preserved. Same as 3.4.2, 3.4.1 and 3.4.0.

3.4.0 - Goodbye v1 API + Support for unbound cases + Bugfix with marks + Fixtures in case files

  • 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

3.3.0 - Filter helpers, Current id getter, Support for pytest-asyncio and other plugins

  • 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 !).

3.2.1 - @fixture Bugfix

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

3.2.0 - Automatic fixture_ref + test ordering bugfix

  • 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

3.1.2 - Bugfixes with nesting and pytest-asyncio

  • 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

3.1.1 - Bugfix with ids

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

3.1.0 - Improved cases collection

  • @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

3.0.0 - harmonization of ids and public API for cases info

  • 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.

2.7.2 - Bugfix with doctest

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

2.7.1 - @pytest.mark.usefixtures can be used on case functions

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

2.7.0 - @parametrize_with_cases now supports id customization

  • @parametrize_with_cases now explicitly supports all id customization methods (ids, idgen and idstyle) supported by @parametrize (ids, idgen and idstyle). Updated documentation accordingly. Fixed #151

2.6.0 - better cache for lazy values and support for infinite id generators

  • 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

2.5.0 - case ids glob match improvements

  • 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

2.4.0 - various fixes for test ids and lazy values

  • 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.

2.3.0 - better LazyValue internal API

  • 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

2.2.5 - Marks are now correctly propagated from Case class

  • 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

2.2.4 - Fixes issue

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

2.2.3 - Fixed issue with pytest 3.X

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

2.2.2 - @parametrize_with_cases compatibility improvements

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

2.2.1 - setup.py fix to enforce dependency version

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

2.2.0 - Doc improvements + bugfix for cases requiring fixtures

  • 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

2.1.3 - Missing deprecation warning

  • 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.

2.1.2 - Compatibility fix

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

2.1.1 - Fixed issue with pytest 6

pytest 6 is now supported. Fixes #121

2.1.0 - Internal engine improvements + bugfixes

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

2.0.4 - Bugfix

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

2.0.3 - Bugfixes

  • Fixed wrong module string decomposition when passed to cases argument in @parametrize_with_cases. Fixes #113

  • Autouse fixtures are now correctly used. Fixed #114

2.0.2 - Better string representation for lazy values

Lazy values (so, test cases) now have a much nicer string representation ; in particular in pytest-harvest results tables. Fixes #112

2.0.1 - Better test ids and theory page

  • New documentation page concerning theory of fixture unions. Fixes #109

  • Using a fixture_ref in a new-style @parametrize (with **args or idgen) now outputs a correct id. Fixes #110

2.0.0 - Less boilerplate & full pytest alignment

I am very pleased to announce this new version of pytest-cases, providing a lot of major improvements. Creating powerful and complex test suites have never been so easy and intuitive !

Below is a complete list of changes, but the user guide has also been updated accordingly so feel free to have a look to get a complete example-based walkthrough.

A/ More powerful and flexible cases collection

New @parametrize_with_cases decorator to replace @cases_data (deprecated).

  1. Aligned with pytest:

    • now argnames can contain several names, and the case functions are automatically unpacked into it. You don't need to perform a case.get() in the test anymore !

      @parametrize_with_cases("a,b")
      def test_foo(a, b):
          # use a and b directly !
          ...
      
    • cases are unpacked at test setup time, so the clock does not run while the case is created - in case you use pytest-harvest to collect the timings.

    • @parametrize_with_cases can be used on test functions as well as fixture functions (it was already the case in v1)

  2. Easier to configure:

    • the decorator now has a single cases argument to indicate the cases, wherever they come from (no module argument anymore)

    • default (cases=AUTO) automatically looks for cases in the associated case module named test_xxx_cases.py. Users can easily switch to alternate pattern cases_xxx.py with cases=AUTO2. Fixes #91.

    • cases can sit inside a class, like what you're used to do with pytest. This additional style makes it much more convenient to organize cases and associated them with tests, when cases sit in the same file than the tests. Fixes #93.

    • an explicit sequence can be provided, it can mix all kind of sources: functions, classes, modules, and module names as strings (even relative ones!).

      @parametrize_with_cases("a", cases=(CasesClass, '.my_extra_cases'))
      def test_foo(a):
          ...
      
  3. More powerful API for filtering:

    • a new prefix argument (default case_) can be used to define case functions for various type of parameters: welcome user_<id>, data_<id>, algo_<id>, model_<id> ! Fixes #108

    • a new glob argument receiving a glob-like string can be used to further filter cases based on their names. For example you can distinguish *_success from *_failure case ids, so as to dispatch them to the appropriate positive or negative test. Fixes #108

    • finally you can still use has_tag and/or provide a filter callable, but now the callable will receive the case function, and this case function has a f._pytestcase attribute containing the id, tags and marks - it is therefore much easier to implement custom filtering.

B/ Easier-to-define case functions

  • Case functions can start with different prefixes to denote different kind of data: e.g. data_<id>, user_<id>, model_<id>, etc.

  • Case functions can now be parametrized with @parametrize or @pytest.mark.parametrize, just as in pytest ! This includes the ability to put pytest marks on the whole case, or on some specific parameter values using pytest.param. @cases_generator is therefore now deprecated but its alternate style for ids and arguments definition was preserved in @parametrize, see below.

  • Now case functions can require fixtures ! In that case they will be transformed into fixtures and injected as fixture_ref in the parametrization. Fixes #56.

  • New single optional @case(id=None, tags=(), marks=()) decorator to replace @case_name and @case_tags (deprecated): a single simple way to customize all aspects of a case function. Also, @test_target completely disappears from the picture as it was just a tag like others - this could be misleading.

C/ Misc / pytest goodies

  • New aliases for readability: @fixture for @fixture_plus, and@parametrize for @parametrize_plus (both aliases will coexist with the old names). Fixes #107.

  • @parametrize was improved in order to support the alternate parametrization mode that was previously offered by @cases_generator, see api reference. That way, users will be able to choose the style of their choice. Fixes #57 and #106.

  • @parametrize now raises an explicit error message when the user makes a mistake with the argnames. Fixes #105.

  • More readable error messages in @parametrize when lazy_value does not return the same number of argvalues than expected from the argnames.

  • Any error message associated to a lazy_value function call is not caught and hidden anymore but is emitted to the user, for easier debugging.

  • Fixed issue with lazy_value when a single mark is passed in the constructor.

  • lazy_value used as a tuple for several arguments now have a correct id generated even in old pytest version 2.

  • New pytest goodie assert_exception that can be used as a context manager. Fixes #104.

1.17.0 - lazy_value improvements + annoying warnings suppression

  • lazy_value are now resolved at pytest setup stage, not pytest call stage. This is important for execution time recorded in the reports (see also pytest-harvest plugin). Fixes #102

  • A function used as a lazy_value can now be marked with pytest marks. Fixes #99

  • A lazy_value now has a nicer id when it is a partial. Fixes #97

  • Removed annoying PytestUnknownMarkWarning warning message when a mark was used on a case. Fixes #100

1.16.0 - New lazy_value for parameters

  • New marker lazy_value for parametrize_plus. Fixes #92

1.15.0 - better parametrize_plus and smaller dependencies

  • Better support for pytest.param in parametrize_plus and also in fixture_union and fixture_param[s]. Improved corresponding ids. Fixed #79 and #86

  • New @ignore_unused decorator to protect a fixture function from the "NOT_USED" case happening when the fixture is used in a fixture union.

  • Removed six, wrapt and enum34 dependencies

  • (Internal) submodules reorganization for readability

  • (Internal) suppressed a lot of code quality warnings

1.14.0 - bugfixes and hook feature

  • Fixed ids precedence order when using pytest.mark.parametrize in a fixture_plus. Fixed #87

  • Fixed issue with fixture_union when using the same fixture twice in it. Fixes #85

  • Added the possibility to pass a hook function in all API where fixtures are created behind the scenes, so as to ease debugging and/or save fixtures (with stored_fixture from pytest harvest). Fixes #83

  • Fixture closures now support reordering when no unions are present. This suppressed the annoying warning "WARNING the new order is not taken into account !!" when it was not relevant. Fixes #81

1.13.1 - packaging improvements

  • packaging improvements: set the "universal wheel" flag to 1, and cleaned up the setup.py. In particular removed dependency to six for setup and added py.typed file. Fixes #78

1.13.0 - @cases_generator default names

@cases_generator now has a default value for the names template, based on the parameters. Fixes #77.

1.12.4 - Bugfix

Fixed ValueError when a product of unions was used on a test node, for example when two parametrize_plus using fixture_refs were used on the same fixture or test function. Fixed #76

1.12.3 - Improved error messages

Improved error message when something that is not a fixture is used in unpack_fixture or fixture_union. Fixed #75

1.12.2 - Warning fix

Fixed deprecation warning #74

1.12.1 - Bugfixes

  • Now using module name and not file path to detect symbols in cases files that are imported from elsewhere and not created locally. Indeed that was causing problems on some ^platforms where a .pyc cache file is created. Fixes #72

  • Fixed PluginValidationError when pytest_fixture_plus or pytest_parametrize_plus were used in a conftest.py file. Fixes #71. According to discussion in pytest#6475, pytest_fixture_plus and pytest_parametrize_plus are now renamed to fixture_plus and parametrize_plus in order for pytest (pluggy) not to think they are hooks. Old aliases will stay around for a few versions, with a deprecation warning.

1.12.0 - better test ids for parametrized tests with fixture refs + bugfix

  • Improved test ids for the cases where fixture_ref is used in the parameters list in @pytest_parametrize_plus. Fixed #69. Thanks last-partizan for the suggestion !

  • Fixed TypeError: got an unexpected keyword argument 'indirect' with pytest 5+. Fixed #70.

1.11.9 - bugfix

FixtureClosureNode is now able to properly handle ignore_args, and now supports that plugins append fixtures to the closure, such as pytest-asyncio. Added corresponding tests. Fixes #68

1.11.8 - bugfix

Fixed KeyError issue happening when a fixture is not found. Now users will see the "normal" error message from pytest ("fixture <name> not found"). Fixed #67.

1.11.7 - bugfix

Fixed ValueError issue happening with indirectly parametrized fixtures. Fixed #64.

1.11.6 - pyproject.toml

raddessi added a pyproject.toml - thanks! Fixed #65.

1.11.5 - bugfix

pytest_parametrize_plus was not working correctly with test classes, leading to fixture 'self' not found. Fixed #63.

1.11.4 - python 2 bugfix

Fixed issue happening with @pytest.mark.parametrize with python 2. Fixed #62.

1.11.3 - minor improvements

Better error message when users use THIS_MODULE in cases= instead of module=.

Added __version__ package-level attribute.

1.11.2 - Increased tolerance to other plugins + bugfix

Now when other plugins try to manipulate the fixture closure, warning messages are emitted but no error is raised. Fixed #55.

Also fixed issue #58 happening with doctest.

1.11.1 - Added six dependency explicitly

It was missing from setup.py.

1.11.0 - fixture_ref can now be used inside tuples, leading to cross-products

Fixes #47.

1.10.2 - More intuitive error messages

Now raising an explicit InvalidParamsList when pytest parametrize argvalues are incorrect. See #54

1.10.1 - Bugfix

Fixed #52.

1.10.0 - New feature: fixtures unpacking

You can now unpack a fixture iterable into several individual fixtures using unpack_fixture or using @pytest_fixture_plus(unpack_into=<names>). This is also available in union_fixture(unpack_into=<names>). Fixed #50 and #51.

1.9.3 - Bugfix

Fixed issues when parametrize argnames contains a list. This fixed #49

1.9.2 - Bugfix with pytest 3.7

Fixed #48.

1.9.1 - Bugfix with pytest 3.7

Fixed #48.

1.9.0 - New --with-reorder commandline option

New commandline option '--with-reorder' to change the reordering startegy currently in application. Fixes #45.

The --with-reorder "skip" mode was not working correctly in presence of marks, fixed it. Fixed #46.

1.8.1 - BugFixes

Ids should not be used when setting a NOT_USED parametrization. Fixes #43

Fixed issue with ordering and setup/teardown for higher-level scope fixtures (session and module scopes) when using union fixtures. Fixes #44

1.8.0 - Better ids for fixture unions

New:

  • fixture_union now accept a non-None value for ids. It also has a new idstyle argument allowing users to change the style of ids used. Finally pytest_parametrize_plus relies on this ids argument to set a more readable list of ids for the created union. Fixes #41.

Misc:

  • Added non-regression test for fixture order. It passes already for all recent pytest versions (after 3.3). Fixes #42

1.7.0 - New @pytest_parametrize_plus allowing fixture references to be used in parameter values

New decorator @pytest_parametrize_plus able to handle the case where a fixture_ref(<fixture_name>) is present in the parameter values list. This decorator can be applied both on test functions and fixtures (if they are decorated with @pytest_fixture_plus). Fixes #40

Major refactoring of the "union fixtures" mechanism.

  • The NOT_USED status is now correctly propagated between dependent fixtures. This should fix a few cases where user fixtures were setup/teardown while not used in the current test node.
  • Empty fixture unions are not permitted anymore.
  • The way unions are handled in test parametrization was redesigned. The new design is based on a two-steps approach: first build the fixture closure for each node as a tree (and not a list as in pytest), and then apply parametrization intelligently based on this tree structure. This fixes several unintuitive behaviours that were happening with unions.

Note: interestingly this also fixes pytest#5054.

1.6.3 - Minor exception enhancement

Improved the error message when the name template is wrong in @cases_generator. Fixes #39.

1.6.2 - bug fixes

fixture_union:

  • Changed the repr of NOT_USED to pytest_cases.NOT_USED.

  • @pytest_fixture_plus now correctly handles the NOT_USED when fixtures in the union do not contain any parameter. Fixes #38.

param_fixtures:

  • param_fixtures now delegates to param_fixture when a single parameter name is provided. This is more consistent. Fixed #36.

  • param_fixture[s] now support all arguments from fixture (scope and autouse in particular).

1.6.1 - @pytest_fixture_plus improvement to handle NOT_USED cases

Fixed issue where fixtures get called with NOT_USED as a parameter when using a fixture_union. This issue is actually only fixed in @pytest_fixture_plus, if you use @pytest.fixture you have to handle it manually. Fixes #37.

1.6.0 - fixture_union and param_fixture[s] bugfix

New fixture_union method to create a fixture that is the union/combination of other fixtures. This is an attempt to solve this pytest proposal.

Also, param_fixture and param_fixtures can now be used without necessarily storing the return value into a variable: they will automatically register the created fixtures in the calling module.

Finally, fixed a bug with param_fixtures when called to create a fixture for a single parameter.

1.5.1 - param_fixtures bugfix

Fixed param_fixtures issue: all parameter values were identical to the last parameter of the tuple. Fixes #32.

1.5.0 - new helpers param_fixture and param_fixtures

Following Sup3rGeo's proposal, introduced two helper methods to create simple "parameter fixtures". Fixes #31.

1.4.2 - parametrized @pytest_fixture_plus minor bug fix

@pytest_fixture_plus now correctly honors parameter id and marks overriden at single parameter level using pytest.param. Fixed #30.

1.4.1 - parametrized @pytest_fixture_plus minor bug fix

Fixed @pytest_fixture_plus in case it is used with parametrize and one parameter is itself customized using pytest.param. Fixed #29.

1.4.0 - @pytest_fixture_plus major improvement

  • Major improvement of @pytest_fixture_plus: instead of generating fixtures, it now correctly parametrizes the fixture. Skip/fail Marks are correctly copied too. Fixes #28.

  • pytest_fixture_plus does not accept the params and ids arguments any more, it only relies on parametrization marks.

1.3.3 - parametrized @pytest_fixture_plus Bugfix

Fixed minor bug with parametrized @pytest_fixture_plus: spaces are now correctly removed when multiple parameter names are provided in the same parametrize call. Fixes #27.

1.3.2 - parametrized @pytest_fixture_plus Bugfix

Fixed bug with @pytest_fixture_plus when used in parametrized mode. Fixes #26. Thanks Sup3rGeo!

1.3.1 - Minor dependency change

Now using decopatch to create the decorators.

1.3.0 - More flexible case generators names + Minor dependency change

Cases generators can now support explicit name lists, and name generator callables, in addition to the name template strings. Fixed #24.

Dependency to decorator has been dropped and replaced with makefun. Fixed #25.

1.2.2 - fixed bug with marks on cases with pytest 3.3

Marks on cases are now also working with pytest 3.3. Fixed #23.

Ids for marked tests are now better managed. A new function get_pytest_parametrize_args is now used to transform the list of cases obtained by get_all_cases(module), into the list of marked cases and ids required by @pytest.mark.parametrize. The doc has been updated to explain this for advanced users wishing to perform this step manually.

1.2.1 - fixed id of test cases with marks

Id of test cases with marks was appearing as ParameterSet. Fixed it.

1.2.0 - @pytest.mark can be used on cases + @pytest_fixture_plus parametrization order bugfix

Pytest marks such as @pytest.mark.skipif can now be used on case functions. As a consequence, get_all_cases is now the recommended function to use instead of extract_cases_from_module to perform manual collection. Indeed get_all_cases correctly prepares the resulting parameters list so that pytest sees the marks. Fixed #21.

Fixed parametrization order when @pytest_fixture_plus is used with several @pytest.mark.parametrize. Fixed #22.

1.1.1 - Improved generated fixture names for @pytest_fixture_plus

When @pytest_fixture_plus is used on a function marked as parametrized, some fixtures are generated (one for each parameter). Generated fixture names now follow the pattern <fixturename>__<paramname>. Fixed #20.

1.1.0 - New @pytest_fixture_plus

New decorator @pytest_fixture_plus allows to use several @pytest.mark.parametrize on a fixture. Therefore one can use multiple @cases_data decorators, too. Fixes #19. Note: this is a temporary feature, that will be removed if/when pytest supports it.

1.0.0 - @cases_fixture + pytest 2.x support

Pytest 2.x is now supported. Fixes #14.

New feature: @cases_fixture ! Now you can put your cases data retrieval in a fixture so that its duration does not enter into the test duration. This is particularly interesting if you use pytest-harvest to create benchmarks: you probably do not want the case data retrieval/parsing to be counted in the test duration, especially if you use caching on the case function to accelerate subsequent retrievals. Fixes #15.

0.10.1 - minor encoding issue in setup.py

0.10.0 - support for python 2

Python 2 is now supported. Fixed #3.

  • Note: CaseData, Given, ExpectedNormal, ExpectedError, and MultipleStepsCaseData type hints is not created in python 2 and python<3.5

0.9.1 - pytest-steps is now an independent project

  • Light refactoring: some internal function names are now private, and there are now two submodules.
  • pytest-steps is now an independent project. Examples in the documentation have been updated
  • New documentation page: API reference

0.8.0 - Filtering can now be done using a callable.

  • @cases_data: the filter argument now contains a filtering function. WARNING: the previous behaviour is still available but has been renamed has_tag. Fixes #8.

0.7.0 - Hardcoded cases selection, and multi-module selection

  • @cases_data has a new parameters cases that can be used to hardcode a case or a list of cases. Its module parameter can also now take a list of modules

0.6.0 - Case parameters and better test suites

  • get_for is deprecated: it was too specific to a given case data format.
  • MultipleStepsCaseData was fixed to also support multiple inputs.
  • Case functions can now have parameters (even case generators). This is particularly useful for test suites. Fixes #9.

0.5.0 - support for test suites

  • test functions can now be decorated with @test_steps to easily define a test suite with several steps. This fixes #7.

0.4.0 - support for data caching with lru_cache

  • cases can now be decorated with @lru_cache. @cases_generator also provides a lru_cache parameter to enable caching. Fixes #6.

0.3.0 - case generators

  • New decorator @cases_generator to define case generators. Fixes #1.
  • Also, removed unused functions is_expected_error_instance and assert_exception_equal

0.2.0 - THIS_MODULE constant + Tagging/Filtering + doc

  • New constant THIS_MODULE so that cases and test functions can coexist in the same file. This fixes #5.

  • Added @test_target and @case_tags decorators for case functions, and added filter parameter in @cases_data. This allows users to :

    • tag a case function with any item (and in particular with the reference to the function it relates to),
    • and to filter the case functions used by a test function according to a particular tag.

This fixes #4.

  • Improved documentation

0.1.0 - First public version

  • Initial fork from private repo
