I went ahead and created a test function with

    def test_hello():

but the timeout was not honoured.  Then i skimmed the docs :)
added "timeout_method = signal" to my ini-file and ran, still not honoured.
Then i figured i need to set some dummy "timeout = 10" in the ini - and now 
i get the proper timeout of 1 second.

I understand the hesitance to grab a general name like "timeout" but then
again installing "pytest-timeout" is a deliberate act and it grabbing the
"timeout" marker is not surprising IMO.  So i'd kindly encourage you to
go for it. I wonder btw. if the output of "--markers" should be merged with
"--help".  The latter would get yet longer but then again it's nice to 
have all the info at a fingertip.

Another feedback item: "@pytest.mark.timeout(5, 'signal')" ought to work.
It's slightly awkward because of the marker args/kwargs API but it's expected
from a pure user perspective i think.

Moreover i'd eventually like to include the timeout plugin
in pytest core.  It's an important feature for functional testing.

Here is what i did for eventlet (only accessing the decorator here):


cheers & thanks,
