How can I run parallel jobs in GitHub Actions?

How can I run parallel jobs in GitHub Actions?

You can run parallel jobs in GitHub Actions by defining multiple jobs in your workflow YAML file. Each job can run independently.

Can you show me an example of a YAML configuration for that?

Sure! Here's a simple example:

name: CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2

  test:
    runs-on: ubuntu-latest
    steps:
      - name: Run tests
        run: npm test

What happens if one of the jobs fails?

If one of the jobs fails, the overall workflow will be marked as failed. However, other jobs that are independent will still run.

Can I control the order of job execution?

Yes, you can control the order by using the needs keyword to specify dependencies between jobs.
