[Pydev-code] Code coverage diff?

[Heikki T. <hj...@co...>]

I just read about some research that was done by an old colleague of
mine. The premise was that if a programmer is looking for a piece of
code, for example the code that handles resizing of an element on
screen, it would be much easier to do if you could do two code coverage
runs where in one run you would resize the element and in the second you
wouldn't. In many cases her test subjects could not even find some
tricky pieces of code without such a coverage diff tool.

She released a very rough version of such a tool for Java, called
Tripoli (http://programmerproductivity.info/tripoli/index.php).

While the typical Python program will likely have far fewer lines of
code executed than many other languages (especially Java), it seems to
me that coverage diff tool for Python would still be really useful.

How hard would it be to add support for such a thing in PyDev? Does
anyone else have any interest in this?
