Convert HPC output into lcov.info files that can be uploaded to coverage services, like Codecov.

Quickstart

Stack

  1. Run stack install hpc-lcov
  2. Run your test(s) with coverage, e.g. stack test --coverage
  3. Run hpc-lcov
  4. Upload the generated lcov.info file to your coverage service

FAQs

How do I convert coverage for an executable?

Note: If you have both tests and executables, HPC will write outputs to the same file. Because of this, you'll have to load the coverage for each separately, with a stack clean in between.

  1. Build the executable with coverage enabled (e.g. stack build --coverage)
  2. Run the executable
  3. This should generate a .tix file in the current directory
  4. Run the following, specifying the package that builds the executable: bash stack exec -- hpc-lcov --file my-exe.tix --main-package my-package

How do I merge coverage files?

  1. Install LCOV (e.g. brew install lcov)
  2. Run

    lcov -a lcov1.info -a lcov2.info ... > lcov.info
