Is there any tool/library that calculate percent of \"condition/decision coverage\" of python code. I found only coverage.py but it calculates only percent of \"statement covera
Are you looking for cyclomatic complexity (Wikipedia)? It basically computes the number of paths through a piece of code. There are some projects to compute that for Python code, for example PyMetrics or this one. Google will certainly bring up more.
But I don't know of any further integration with unit tests that will show you the coverage.
