pytest-timeout Description

pytest-timeout is a plugin for py.test which will terminate tests after a certain timeout. When doing so you will get a stack dump of all threads running at the time. This is useful when e.g. running tests under a continuous integration (CI) server.UsageInstall via:pip install pytest-timeoutand then enable the plugin, either from the command line:py.test -p timeoutor more conveniently from within the test module or conftest.py:pytest_plugins = 'timeout'You can change the timeout using the --timeout parameter which sets the timeout in seconds.How It WorksThis plugin works in one of two ways. If the system supports the SIGALRM signal an alarm will be scheduled when the tests starts and cancelled when it finishes. If the alarm expires during the test the signal handler will use pytest.fail() to interrupt the test after having dumped the stack of any other threads running to stderr.If the system does not support SIGALRM or the --nosigalrm option was used then a timer thread will be used instead. Once more, if this timer is not cancelled before it expires it will dump the stack of all threads to stderr before terminating the entire py.test process using os._exit(1).The downside of the SIGALRM method is that the signal is used by the test framework. If this signal is used by the code under test you will need to use the --nosigalrm option. The limitation of the timer thread however is the extra overhead of creating a thread for each executed test and the fact that after one timeout the entire process is stopped and no further tests are executed.Product's homepage
