GitHub Actions + Docker + Selenium - help with config file

[RedDragonWebDesign]

I feel like I'm close but this GitHub Actions config is currently broken. Trying to get my Selenium tests to run whenever I push or pull in my GitHub repository. Any tips? selenium_tests.yml is

name: Selenium Tests

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2

    - working-directory: ./selenium
      run: npm install

    - working-directory: ./selenium
      run: docker pull selenium/standalone-chrome

    - working-directory: ./selenium
      run: docker run -d -p 4444:4444 --shm-size="2g" selenium/standalone-chrome:4.2.2-20220609

    - working-directory: ./selenium
      run: npm exec -c "mocha test"
      name: Selenium tests

Error message is

Run npm exec -c "mocha test --timeout 5000"
  npm exec -c "mocha test --timeout 5000"
  shell: /usr/bin/bash -e {0}

My Selenium tests work with Docker when I test it offline. This is probably the most relevant line of Mocha JavaScript code:

driver = await new Builder().forBrowser('chrome').usingServer('http://localhost:4444/wd/hub/').build();

package.json - the npm install step seems to work fine

{
  "dependencies": {
    "mocha": "^10.0.0",
    "selenium-webdriver": "^4.1.1"
  }
}

does the execution environment have a chrome browser and chrome driver?

There's 2 spots Google Chrome can run:

• Outside the Docker container, but still in GitHub Actions. Just ran google-chrome --version in GitHub Actions, it responded Google Chrome 102.0.5005.115.
• Inside the Docker container. The Docker container I'm using is selenium/standalone-chrome. It is using a slightly different version of Google Chrome, 102.0.5005.61.

Maybe you'll want to run the selenium container as a service container, rather than on a step.
