Hi,
I was doing some refactoring in a code base with reasonable but not
perfect unit test coverage. While reviewing my changes I was
wondering: of the lines changed, which ones are not covered by unit
tests? If I had a report showing just that, I could make sure that
whenever I commit a change, the unit test coverage for the changed
lines would be 100%. Thus continuously improving overall coverage and
reducing the risk of changes at the same time. Wouldn't that be neat?
This started out as conversation on twitter (see
https://twitter.com/#!/fniessink/status/195166296848072704) with Ned
Batchelder because I was thinking that this would be an excellent
feature for coverage.py . What do you guys think?
Thanks, Frank
