How do job dependencies work in GitHub Actions?

In GitHub Actions, job dependencies allow you to control the order in which jobs run. You can specify that a job should only run after another job has completed successfully.

Can you give me an example of how to set that up in a workflow?

Sure! You can use the needs keyword in your workflow YAML file. For example:

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Build
        run: echo 'Building...'

  test:
    runs-on: ubuntu-latest
    needs: build
    steps:
      - name: Test
        run: echo 'Testing...'

What happens if a job that another job depends on fails?

If a job that another job depends on fails, the dependent job will not run. This helps ensure that subsequent jobs only execute when their prerequisites are successful.
