Hi all,
i am hacking on a new plugin to go into py.test-1.0.1 and i am
doing that in documentation-driven style. So i am interested
in feedback and comments on the below soon-to-become reality
"pytest_testfiles" plugin.
best & thanks,
holger
pytest_testfiles.py: determine test files for command line specified args.
===========================================================================
usage example: specifying testfiles in a python module
-----------------------------------------------------
If you have a module ``mymodule.py`` you can specify test files like this::
# content of: mymodule.py
# relative paths
__testfiles__ = ['test/test_unittest.py', 'test/test_functional.py']
and if you then type::
py.test mymodule.py
then this will run the test files which were specified relatively
to the directory of ``mymodule.py``.
Ordering is significant: if you specify quick-running unit-tests
first followed by slower running functional tests then issuing
commands like ``py.test -x`` allows to find failures quickly
and the easier-to-debug ones first.
usage example: specifying project-specific testfile patterns
--------------------------------------------------------------
Suppose your project has this layout::
app/
sub1/
module1.py
tests/
unit/
test_module1.py
functional/
test_one.py
test_two.py
you may specify filematching rules for finding tests like this::
# contents of: conftest.py
conf_testfilepatterns = ["{topdir}/tests/unit/test_{basename}",
"{topdir}/tests/functional/*.py"]
and if you then type::
py.test app/sub1/module1.py
the specified testfile patterns will be applied to check if there are matching
test files. In our example we will run test files in the following order::
tests/unit/test_module.py
tests/functional/test_one.py
tests/functional/test_two.py
default is to look for test files being close to code
----------------------------------------------------------
If no ``conf_testfilepatterns`` are specified, py.test will use this
as a default setting::
conf_testfilepatterns = [
"*/test_{purebasename}.py",
"**/test_*.py",
"**/*_test.py"
]
Note that each matching test file will only be run at most once.
Substitutions
-------------------
The following substitutions are performed for each file-or-directory command
line argument::
dirname the dirname of the file
basename basename of the file
purebasename basename without the extension
topdir first upwards parent directory not containing __init__.py
