Welcome to pytest-2.0.0, a major new release of “py.test”, the rapid easy Python testing tool. There are many new features and enhancements, see below for summary and detailed lists. A lot of long-deprecated code has been removed, resulting in a much smaller and cleaner implementation. See the new docs with examples here:
A note on packaging: pytest used to part of the “py” distribution up until version py-1.3.4 but this has changed now: pytest-2.0.0 only contains py.test related code and is expected to be backward-compatible to existing test code. If you want to install pytest, just type one of:
pip install -U pytest easy_install -U pytest
Many thanks to all issue reporters and people asking questions or complaining. Particular thanks to Floris Bruynooghe and Ronny Pfannschmidt for their great coding contributions and many others for feedback and help.
best, holger krekel
new invocations through Python interpreter and from Python:
python -m pytest # on all pythons >= 2.5
or from a python program:
import pytest ; pytest.main(arglist, pluginlist)
see http://pytest.org/2.0.0/usage.html for details.
new and better reporting information in assert expressions if comparing lists, sequences or strings.
new configuration through ini-files (setup.cfg or tox.ini recognized), for example:
[pytest] norecursedirs = .hg data* # don't ever recurse in such dirs addopts = -x --pyargs # add these command line options by default
improved standard unittest support. In general py.test should now better be able to run custom unittest.TestCases like twisted trial or Django based TestCases. Also you can now run the tests of an installed ‘unittest’ package with py.test:
py.test --pyargs unittest
new “-q” option which decreases verbosity and prints a more nose/unittest-style “dot” output.
many many more detailed improvements details
py.test.config is now only available if you are in a test run.
the following (mostly already deprecated) functionality was removed:
py.test.collect.Directory does not exist anymore and it is not possible to provide an own “Directory” object. If you have used this and don’t know what to do, get in contact. We’ll figure something out.
Note that pytest_collect_directory() is still called but any return value will be ignored. This allows to keep old code working that performed for example “py.test.skip()” in collect() to prevent recursion into directory trees if a certain dependency or command line option is missing.
