You can run the test suite with explicit test names (tests/run MyClass.test_foo) if you want to debug a particular test and only run that one.

Hi,
Do yuo know how to repeat only failed tests? Some call in tearDown…

Sorry for not following up on my comment. The logcapture extension does capture log messages emitted using Python’s logging system. I assumed that was how you generated the log file but I only now realized that it is about a different log file. You could still always “log the log” (i.e. do something like logger.debug(log_output) but then Ulrich’s solution is probably easier.

Ah, thanks Ulrich!

Sorry, should have been main(), not runt(), which was a typo anyway.

From http://docs.python.org/library/unittest.html, it’s just “unittest.main(buffer=True)” and you won’t see any of the output of setUp, test and tearDown unless the thing fails. Alternatively, you can pass -b or –buffer on the commandline.

Should be enabled by default, if you ask me.

Ah, do you have an example how to do that?

You can print() things unconditionally and tell unittest.runt() to buffer that output. In case of success, the output is discarded, otherwise it is displayed along with the fault.

Marcel,

indeed I do use nose for some of my Python projects; these are tests for gnome-settings-daemon which uses autotools (and is otherwise a C project). But doesn’t this only capture things you already print to stdout/err? What I want is to only show the daemon log for a test that fails.

Ups, that link was missing an l in the end…:

If you’d be using the nose testing framework (and why would you use anything else ?), you’d have this behaviour by default:
