New issue 238: Add an easy way for plugins to format objects for idmaker
https://bitbucket.org/hpk42/pytest/issue/238/add-an-easy-way-for-plugins-to-format

Gustavo Picon:

One of the things I missed when I ported a hacky dynamic unittest suite to pytest fixtures, was the information I got from the test names. I parametrize 6 different django models in every test, but in the report I saw something like:

    test_add_sibling_first[model0]
    test_add_sibling_first[model1]
    test_add_sibling_first[model2]
    ...

Which wasn't helpful at all. I solved this problem by [monkeypatching _pytest.python.idmaker](https://bitbucket.org/tabo/django-treebeard/src/fd57de9692913126a31c87c909a45f84a919fffe/treebeard/tests/conftest.py?at=default#cl-20). Now I have [nicer results](https://tabo.pe/jenkins/job/django-treebeard/34/TOX_DB=sqlite,TOX_DJANGO=dj15,TOX_PYTHON=py32,os=windows/testReport/treebeard.tests.test_treebeard/TestAddSibling/), like:

    test_add_sibling_first[AL_TestNode]
    test_add_sibling_first[AL_TestNodeProxy]
    test_add_sibling_first[MP_TestNode]
    ...

It would be better if pytest provided an interface for plugins to handle different object types, so for instance pytest_django could register itself as being in charge of formatting all django orm objects and views.
