Coverage tracers

Gcov / gcovr

1. Make sure to compile and link with the --coverage flag. Disable optimizations and switch on debugging.
2. Execute your application / your tests. This will generate .gcda-files.
3. Collect the coverage information and generate the report using gcovr:

gcovr -x -r . > report.xml

Bullseye

Create the XML coverage report with:

covxml -f UTCoverage.cov -o bullseyecoverage-result-0.xml

To merge two coverage files (e.g. to obtain the overall coverage):

covmerge -c ITCoverage.cov UTCoverage.cov -f ALLCOVERAGE.cov
