python coverage testing

coverage.py: actively developed, simple command line execution for html output. integration into my test framework would require some work with the api, though it already has a nose plugin i could look at. figleaf is based on coverage.py but runs faster because it ignores python builtins by default. better separation between code analysis and reporting, so you can more easily combine results from multiple runs. maybe not quite as much spit and polish. the coverage langlet module (?) takes a different approach to coverage monitoring by inserting sensor objects into block entry points of the compiled code. the module seems to be more alpha quality than ned batchelder's, but perhaps an interesting alternative if that one doesn't work out for some reason. i think i'll try coverage and/or figleaf to see if they are helpful beyond the builtin trace capability.
