implemented by a slight internal refactoring and the introduction
of a new hook ``pytest_exception_interact`` hook.
- fix issue341: introduce new experimental hook for IDEs/terminals to
intercept debugging: ``pytest_exception_interact(node, call, report)``.
don't use autouse fixtures for now because it would cause a proliferation
and overhead for the execution of every test. Rather introduce a
node.addfinalizer(fin) to attach a finalizer to the respective node
and call it from node.setup() functions if the setup phase succeeded
(i.e. there is no setup function or it finished successfully)
When an autouse fixture in a plugin was encountered None was stored as nodeid
where it used to be ''. This broke the lookup of autouse fixtures later on.
This also adds another test for the normal fixture ordering which was slightly
wrong: a fixture without location was always added at the front of the fixture
list rather then at the end of the fixtures without location but before the
fixtures with location.
Conftests are plugins with a location attached to them while other
plugins do not have a location. When ordering fixturedefs those from
plugins without a location need to be listed first.
- When not specifying ids, let None and bools use their native string form (like str, int, float) rather than obfuscated form used for objects
- When specifying ids, explicitly raise a ValueError if a different number of ids are specified compared to the test cases
- Add tests for both these items.
address some comments by @hpk42 on 0b9d82e :
- move tests into their own class, rename
- add test showing metafunc.parametrize called in pytest_generate_tests rather than as decorator
- add test and fix single-argname case
- convert two loops into one in parametrize()
also
- renamed 'input' to 'n', since 'input' is a built-in
pytest-rerunfailures plugins) by re-initializing and removing
request/funcargs information in runtestprotocol() - which is a slightly
odd place to add funcarg-related functionality but it allows all
pytest_runtest_setup/teardown hooks to properly see a valid
request/funcarg content on test items.
When the conftest.py files are looked for intially they got loaded
starting from the subdir ending at the parent dir(s). Later on during
collection any conftest.py files are loaded starting from the parent
dir ending at the subdir. Due to how extending fixtures works the
latter is correct as otherwise the wrong fixture will be available.
So this changes the initial conftest loading to start at the root and
go towards the subdir.
This does also affect the order of other hooks, hence the order of the
reporting being different in testing/test_terminal.py.
