FAQs
How do I convert coverage for an executable?
Note: If you have both tests and executables, HPC will write module information to the same file. Because of this, you’ll have to load the coverage for each separately, with a stack clean in between.
- Build a single executable with coverage enabled (e.g.
stack build :my-exe --coverage) - Run the executable
- This should generate a
.tixfile in the current directory - Run the following, specifying the package that builds the executable:
stack exec -- hpc-lcov --file my-exe.tix --main-package my-package
How do I merge coverage files?
-
Install LCOV (e.g.
brew install lcov) -
Run
lcov -a lcov1.info -a lcov2.info ... > lcov.info
