Creating a URL for each test failure:
py.test --pastebin=failed
This will submit test run information to a remote Paste service and provide a URL for each failure. You may select tests as usual or add for example -x if you only want to send one particular failure.
Creating a URL for a whole test session log:
py.test --pastebin=all
Currently only pasting to the http://paste.pocoo.org service is implemented.
