GitHub Action to automatically unit test shell scripts on every git push using shunit2 and bash-spec-2 unit test frameworks.

Create unit test cases with the syntax of shunit2 and bash-spec-2 unit test frameworks. Store them in one or more script files named <filename>.shunit2 or <filename>.bashspec2, accordingly to the framework used, and residing in a test directory on the root of the repository. You do not need to source the shunit2 and bash-spec-2 scripts inside your unit testing files: it will be done for you by this GitHub Action.

Then create a GitHub workflow referencing vargiuscuola/gen-sh-unittest. For example, put in a workflow with path .github/workflows/sh-unittest.yml the following content:

name: Shell Scripts Unit Testing

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout
      uses: actions/checkout@v2
    - name: Github Action gen-sh-unittest
      id: action-gen-sh-unittest
      uses: vargiuscuola/gen-sh-unittest@master
    - name: gensh-unittest result
      run: echo "The result of gensh-unittest Action was ${{ steps.action-gen-sh-unittest.outputs.result }}"
    - name: Commit files
      run: |
        echo ${{ github.ref }}
        git add .
        git config --local user.email "action@github.com"
        git config --local user.name "GitHub Action"
        git commit -m "CI: Automated build push" -a | exit 0
    - name: Push changes
      if: github.ref == 'refs/heads/master'
      uses: ad-m/github-push-action@master
      with:
        github_token: ${{ secrets.GITHUB_TOKEN }}

This will run all unit testing files found in the directory test in the root of the repository. The fail of any of the unit testing script will cause the failing of this GitHub Action, and consequently of all the workflows referencing it.
