Coco

Coco is a code coverage tool for desktop and embedded software. It instruments code during the build, without changing compilers, build system or test suite, and measures coverage of C, C++, C#, QML, Python and Tcl code up to MC/DC level, with reports for regulated industries and risk metrics.

Coco, formerly Squish Coco from froglogic, is now a commercial product of the Qt Group; froglogic’s page redirects to it.
