Tests that print stuff to stdout or stderr annoy me. They make a successful test run much less satisfying to watch, and they clutter logs when you are trying to debug a failure.
Launchpad has quite a few tests that print stuff. I was going to fix them up today, but I've got a Launchpad branch in progress and I've promised myself that I'll have only one in progress at a time. Besides, the build is broken.
To get a subunit stream including the output itself:
$ gzip -dc testtools-experiment-r11753.subunit.gz | grep -v time: | python tests-with-output.py
To get a list of the tests:
$ gzip -dc testtools-experiment-r11753.subunit.gz | python tests-with-output.py | subunit-ls --no-passthrough
For those interested, Launchpad has roughly one hundred such tests.
As with my last post, I'm left with the feeling that subunit is great but needs a lot more polish. I guess my next step is to figure out how to upstream these.
