calling newbrough/coverage tests with nose causes traceback

[retrogradeorbit]

Tests run fine but then on exit get the following traceback::

Traceback (most recent call last):

Whats the recommended testrunner for this version of coverage?

[retrogradeorbit]

Turns out to be caused by trying to follow branches. Was issuing call with:

nosetests --with-coverage --cover-erase --cover-package=panopticon --cover-branches --cover-html ./tests/*.py

removing the --cover-branches stops the exception from being raised.

Suggest added support for branches, or at least detecting nose cover-branch calls and throwing a more specific 'branches not supported' exception?

Just a +1 on this, ran into the same issue tonight :)
