Unable to find any .xccoverage file

As of Xcode 11 you need to preprocess the xcresult first: https://github.com/ChargePoint/xcparse#code-coverage

[Kaspik]

So finally working solution for this would be something like this (I'm using Github Actions with Danger and build.sh script file called from the yaml file).

build.sh:

  bundle install
  pod install --repo-update
  set -o pipefail && bundle exec fastlane tests
  echo "Running Danger..."
  xcparse codecov ./fastlane/test_output/app.xcresult ./fastlane/test_coverage
  bundle exec fastlane danger_tests
  rm -fr ./fastlane/test_coverage
  rm -rf ./fastlane/build_folder

Fastfile:

1. tests:

  desc "Runs app tests - UNIT + UI tests"
  lane :tests do\
    # First build the project to the build_folder directory
    run_tests(
      workspace: WORKSPACE_NAME,
      scheme: TARGET_NAME,
      derived_data_path: "./fastlane/build_folder",
      build_for_testing: true,
      device: "iPhone 11 Pro",
      code_coverage: true
    )
    # Then run tests without building the project itself
    run_tests(
      workspace: WORKSPACE_NAME,
      scheme: TARGET_NAME,
      derived_data_path: "./fastlane/build_folder",
      test_without_building: true,
      device: "iPhone 11 Pro",
      result_bundle: true,
      output_types: "html",
      prelaunch_simulator: true,
      code_coverage: true
    )
  end

2. danger_tests:

desc "Run Danger check for tests coverage"
  lane :danger_tests do |options|
    danger(
        danger_id: "Tests",
        dangerfile: "DangerfileBuild",
        github_api_token: ENV["GITHUB_API_TOKEN"]
    )
  end

3. DangerfileBuild:

xcov.report(
   scheme: 'TARGET_NAME',
   workspace: 'WORKSPACE_NAME',
   output_directory: 'xcov_output',
   only_project_targets: true
)

As you can see, the problem here is that I have to run xcparse codecov ./fastlane/test_output/app.xcresult ./fastlane/test_coverage ro get the right file from build folder as xcov works on build folder, but danger-xcov is not updated for that.

Would be nice to update this project.
