Usage

The README says Usage: $ nosetests --with-mutations But I get nosetests: error: no such option: --with-mutations I have nosetests: error: no such option: --with-mutations

It also needed unittest2.

If I run your tests I get this output:

C:\Python27\lib\site-packages\nose\plugins\manager.py:395: RuntimeWarning: Unable to load plugin mutations = elcap.plugins:Mutations: No module named elcap.plugins RuntimeWarning)

Hi Frances, thanks for reporting the issue.

This project is no longer maintained and I wrote a few years ago, and I guess now the nose API has changed a little bit.

I tried running the test and got a different errors than yours.

I do not have the time to debug this, but feel free to for this or send me a PR. I guess one can still reuse the ast mutations and probably the import mechanisms.
