code coverage

[fchastanet]

add code coverage https://github.com/SimonKagstrom/kcov

• upload code coverage to deepsource using github action

• coverage Implement test coverage via kcov in our CI bats-core/bats-core#15

  • bats has to be in PATH
  • kcov needs sudo apt install libdw-dev
  • from src dir
    • usr/local/bin/kcov --collect-only --exclude-path=/tmp $PWD/logs/coverage
      bats -r src/Options/generateCommand.bats -j 30
    • usr/local/bin/kcov --collect-only
      --include-path=$(pwd)/src --exclude-pattern=/testsData/ --exclude-path=/tmp --exclude-path=$PWD/vendor
      $PWD/logs/coverage bats -r src -j 30
    • coverage is in logs/coverage/bats/coverage.json
  • if some test has to be excluded
    • add # bats test_tags=no-kcov before the test
  • github https://github.com/bats-core/bats-core/pull/718/files
  • integrate with https://coveralls.io/
  • to integrate coverage of all files even those not tested, I should generate
    a bats file that source all the src files of the framework.
