Pandokia supplies a py.test plugin. It is automatically enabled when you use Pandokia to run a test with py.test.
With this plugin, py.test can also write a Pandokia log file on its own, so you can run it outside Pandokia.:
py.test --pdk foo.py
Documentation for installing py.test is available at http://pytest.org/ . The py.test documentation includes quite a nice Installation and Getting Started section. If you are not already familiar with py.test, it is a good introduction.
Any file matching the pattern *.pytest will be executed with py.test.
The default runner for *.py is nose, but you can override this per-directory by creating a pdk_runners file.
The most convenient way to do it is to declare that all python files should be run with py.test:
You can also mix py.test, nose, and other test runners:
a.py pytest b*.py nose c*.py minipyt d*.py pytest
You can define timeouts for individual tests like this:
@pytest.mark.timeout(3) def test_foo() : # this test always times out time.sleep(6)
The timeout is always specified in seconds. If the test runs longer than that, the plugin will trigger SIGALRM that will raise an exception.
The plugin attempts to detect the application program setting a signal handler for SIGALRM. If a signal handler already exists for SIGALRM when the test starts, or if the test ends with a signal handler that is not the one that the plugin installed, the test will report an error. The exception will identify the signal handling function.
Timeouts are not implemented on Windows.
If the Pandokia plugin is not enabled, the timeout markup has no effect.
This feature is independent of PDK_TIMEOUT.
You can tell your test function the name that Pandokia knows it by like this:
def test_foo(pdk_test_name) : print "My pandokia test name is: ", pdk_test_name
You could use this in data that is reported outside the Pandokia system. For example, when we test a web app, we sometimes include the test name in the browser string so that we can later identify the actions of specific tests in the httpd server logs.
If the pandokia plugin is present but not enabled, the value of pdk_test_name is None.
If the pandokia plugin is not present, pdk_test_name is an unrecognized funcarg and therefore it is an error to use it.
The plugin captures stdout/stderr by replacing sys.stdout and sys.stderr with StringIO.
More work is needed on this feature. Currently, it disables the capsys/capfd capability that is normally present in py.test.
If the pandokia plugin is not enabled, capsys/capfd work as normal for py.test.
