How can I use conditional execution in GitHub Actions?

You can use the if conditional to control when a job or step runs in GitHub Actions. For example, you can specify conditions based on the result of previous jobs.

Can you give me an example of that?

Sure! Here's a simple example:

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

  test:
    runs-on: ubuntu-latest
    needs: build
    if: success()  # This job runs only if the 'build' job is successful
    steps:
      - name: Run tests
        run: npm test

What other conditions can I use?

You can use various conditions like always(), failure(), or even custom expressions to control execution based on specific criteria.
