pytest-fail-slow is a pytest plugin for making tests fail that take too long to run. It adds a --fail-slow DURATION command-line option to pytest that causes any otherwise-passing tests that run for longer than the given duration to be marked as failures. Note that slow tests will still be run to completion; if you want them to instead be stopped early, use pytest-timeout.
A duration can be supplied to the --fail-slow option as either a bare floating-point number of seconds or as a floating-point number followed by one of the following units (case insensitive):
h,hour,hoursm,min,mins,minute,minutess,sec,secs,second,secondsms,milli,millisec,millisecondsus,μs,micro,microsec,microseconds
If pytest-fail-slow marks a test as a failure, the output will include the test's duration and the duration threshold, like so:
________________________________ test_func ________________________________ Test passed but took too long to run: Duration 123.0s > 5.0s
Note: Only the durations for tests themselves are taken into consideration. If a test passes in less than the specified duration, but one or more fixture setups/teardowns take longer than the duration, the test will still be marked as passing.
Installation
pytest-fail-slow requires Python 3.6 or higher and pytest 6.0 or higher. Just use pip for Python 3 (You have pip, right?) to install it:
python3 -m pip install pytest-fail-slow
