py.test 2.0.2: bug fixes, improved xfail/skip expressions, speed ups

Welcome to pytest-2.0.2, a maintenance and bug fix release of pytest, a mature testing tool for Python, supporting CPython 2.4-3.2, Jython and latest PyPy interpreters. See the extensive docs with tested examples here:

If you want to install or upgrade pytest, just type one of:

pip install -U pytest # or
easy_install -U pytest

Many thanks to all issue reporters and people asking questions or complaining, particularly Jurko for his insistence, Laura, Victor and Brianna for helping with improving and Ronny for his general advise.

best, holger krekel

Changes between 2.0.1 and 2.0.2

  • tackle issue32 - speed up test runs of very quick test functions by reducing the relative overhead

  • fix issue30 - extended xfail/skipif handling and improved reporting. If you have a syntax error in your skip/xfail expressions you now get nice error reports.

    Also you can now access module globals from xfail/skipif expressions so that this for example works now:

    import pytest
    import mymodule
    @pytest.mark.skipif("mymodule.__version__[0] == "1")
    def test_function():
        pass
    

    This will not run the test function if the module’s version string does not start with a “1”. Note that specifying a string instead of a boolean expressions allows py.test to report meaningful information when summarizing a test run as to what conditions lead to skipping (or xfail-ing) tests.

  • fix issue28 - setup_method and pytest_generate_tests work together The setup_method fixture method now gets called also for test function invocations generated from the pytest_generate_tests hook.

  • fix issue27 - collectonly and keyword-selection (-k) now work together Also, if you do “py.test –collectonly -q” you now get a flat list of test ids that you can use to paste to the py.test commandline in order to execute a particular test.

  • fix issue25 avoid reported problems with –pdb and python3.2/encodings output

  • fix issue23 - tmpdir argument now works on Python3.2 and WindowsXP Starting with Python3.2 os.symlink may be supported. By requiring a newer py lib version the py.path.local() implementation acknowledges this.

  • fixed typos in the docs (thanks Victor Garcia, Brianna Laugher) and particular thanks to Laura Creighton who also revieved parts of the documentation.

  • fix slighly wrong output of verbose progress reporting for classes (thanks Amaury)

  • more precise (avoiding of) deprecation warnings for node.Class|Function accesses

  • avoid std unittest assertion helper code in tracebacks (thanks Ronny)
