This article covers the coverage analysis of Python:
* Building a network management application
* Installing and running coverage on your test suite
* Generating an HTML report using coverage
* Generating an XML report using coverage
* Getting nosy with coverage

Cobertura is an open source tool that measures test coverage by instrumenting a code base and watching which lines of code are and are not executed as the test suite runs.

Code coverage tools measure how thoroughly tests exercise programs.  They are misused more often than they’re used well. This paper describes common misuses in detail, then argues for a particular cautious approach to the use of coverage.
