This is elcap version 0.2. A nose plugin that tests mutations of your source code.

This is an early release. All comments are welcome.

Acknowledgments: This plugin was built using some of the ideas present on Pymutester: http://pypi.python.org/pypi/pymutester

Usage: $ nosetests --with-mutations

Testing: $ pip install ludibrio, nose $ nosetests tests

Known Limitations:

• The mutators only work when the mutated node has lineno and col_offset
• The TestCoverage plugin has some problems with isolation, hence some lines are not reported as covered, affecting the possible mutations.
• Sometimes the timeout function get stuck and it's not possible to release it.

TODO features:

• improve reporting of what was mutated (wanted to use codegen, but is really unfinished, already fixed many bugs, but there is still lots to do)

Changelog:

• 27/01/2013: Released version 0.2 fixed formatting fixed some bugs refactored code added way to specify custom Mutators added way to stop tests in case they get stuck
• 16/02/2012: Released version 0.1.5 added arguments to skip lines or files improved reporting
• 08/02/2012: Released version 0.1 basic functionality
