There is a superbuild variable WITH_COVERAGE which should turn on code coverage reports for Linux dartclients.
For testing I added this to the MITKDahboardScript:
ctest_coverage( BUILD "${CTEST_BINARY_DIRECTORY}/MITK-build" ) submit(PARTS Test Coverage Done)
The necessary flags are set correclty (-fprofile-arcs -fuse-coverage) and coverage information is generated during CTest runs of the test. However something fails during collection of the data. (No coverage information found)
However, changing into MITK-build and calling ctest -D Experimentalworks perfectly.
This ticket is primarily for reference, I can keep looking at the issue with low priority, if someone wants to take over I'm happy to help
