This action will calculate the code coverage for each PR. It will then comment with the change in coverage on each PR.

Create a file named .github/workflows/ember-code-coverage.yml in your repo and add the following:

name: ember-cli-code-coverage

on: [pull_request]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@master
    - uses: mydea/actions-ember-testing@v1
    - name: Install dependencies
      run: yarn install
    - uses: mydea/ember-cli-code-coverage-action@v1
      with:
        repo-token: "${{ secrets.GITHUB_TOKEN }}"

Note that the GITHUB_TOKEN secret is automatically available, so you don't need to do anything else about that.

By default, it will run yarn test-coverage. Either you add something like this: "test-coverage": "COVERAGE=true ember test" to your package.json file, or you can specify a custom test command:

- uses: mydea/ember-cli-code-coverage-action@v1
  with:
    repo-token: "${{ secrets.GITHUB_TOKEN }}"
    test-command: "yarn my-test-command"

You can also specify a custom coverage-file (defaults to ./coverage/coverage-summary.json), If ember app located not in the root of a repo you should also specify working-directory option.

and a coverage-indicator, which defaults to statement (which defines which type of coverage will be used).
