Hi, i would like to run cypress tests on my Vue project linked to cypress dashboard in Github actions, triggered on push or pull events.
To test my application, wich is written on NodeJS at the backend and Vue in the frontend, i have to run both https server in the github workflow. 
I am using cypress-io/github-action and it worked fine without running the backend server. This was my configuration:

name: End-to-end tests
on: [push]
jobs:
  cypress-run:
    runs-on: windows-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v1
  - name: Cypress run
    uses: cypress-io/github-action@v1
    with:
      record: true
      start: npm run serve --prefix frontend/app
      wait-on: http://localhost:8080
    env:
      CYPRESS_RECORD_KEY: <key>

Now the goal is to have also a running server using:

npm run start # --> node index.js

 So that i can get backend api listening on localhost:8000 (and vue in dev mode is refering to).

But i can not get that to work. I have tried various configuration like this: 

name: End-to-end tests
on: [push]
jobs:
  cypress-run:
    runs-on: windows-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v1
  - name: Run backend
    uses: actions/setup-node@v1
    with:
      node-version: ${{ matrix.node-version }}
      run: npm run start

  - name: Cypress run
    uses: cypress-io/github-action@v1
    with:
      record: true
      start: npm run serve --prefix frontend/nix-app
      wait-on: http://localhost:8080
    env:
      # pass the Dashboard record key as an environment variable
      CYPRESS_RECORD_KEY: <key>

The backend server runs correctly on port 8000, but then the workflow is stuck there! It doesn’t continue on Cypress run because, i guess, it’s waiting the end of the process.
How can i force to go at the next step after the first server is set up?

Another solution that i have tried is to use two different jobs in parallel, but also this is not working because the two servers will not stop running. Then what if cypress tests run before the two servers are up?

Can you suggest something else? Thank you!
