nose-progressive 0.1.2

Features

• Indicate progress in a stationary progress bar rather than scrolling useful tracebacks off the screen or spacing them out with dots and cruft.

• Show tracebacks as soon as they occur rather than waiting until the bitter end. Strip the “Traceback (most recent call last):” off tracebacks so they take less space.

• Identify failed tests in a format that can be fed back to nose, so it’s easy to re-run them.

• Print a filesystem path complete with vi-style line number, so you can paste it to the commandline and be taken straight to the bug in your editor.

• Work great with Django via django-nose (of course).

Installation

pip install nose-progressive

Or, to get the bleeding-edge, unreleased version:

pip install -e \
  git://github.com/erikrose/nose-progressive.git#egg=nose-progressive

Use

nosetests --with-progressive

Example

The following doesn’t quite do it justice; in an actual terminal, the 2 pathname lines after FAIL or ERROR are bold to aid visual chunking, and the progress bar at the bottom is bold as well:

% nosetests --with-progressive

Caveats and known bugs

• Skipped tests get counted in Python 2.6, but they don’t get printed. I consider skips something to be discouraged, so I plan to fix this.

• Tests which themselves write to stderr will smear bits of the progress bar upward if they don’t print complete lines. I hope to fix this with some monkeypatching, but in the meantime, passing –logging-clear-handlers fixes most of these in practice.

• I haven’t tried this in anything but Python 2.6. Bug reports are welcome!

• No tests yet. Ironic? :-)

Future plans

• A proper progress bar. nose doesn’t count tests for us ahead of time, so we’ll have to preflight ourselves.

Kudos

Thanks to Kumar McMillan for his nose-nicedots plugin, which provided inspiration and starting points for the path formatting. Thanks to my support.mozilla.com teammates for writing so many tests that this became necessary.
