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.

See documentation page for details.

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

See documentation page for details.

Fixed #48.

Fixed #48.

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.

See documentation page for details.

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

See documentation page for details.

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

See documentation page for details.

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.

See documentation page for details.

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

See documentation page for details.

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).

See documentation page for details.

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

See documentation page for details.

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.

See documentation page for details.

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

See documentation page for details.

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

See documentation page for details.

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

See documentation page for details.

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

See documentation page for details.

• 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.

See documentation page for details.

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

See documentation page for details.

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

See documentation page for details.

Now using decopatch to create the decorators.
