81 Advanced Pipeline - GitHub Actions - Run jobs with dependency
🔗 Playwright Essentials #81 GitHub Actions: Run Jobs with Dependencies
In this episode, we explore how to structure GitHub Actions workflows with job dependencies, allowing you to control execution order, enforce build logic, and create modular pipelines. Whether you're running Playwright tests, linting code, or deploying to staging, this setup ensures each job runs only when its prerequisites succeed.
🎯 What You’ll Learn:
🧩 Why Job Dependencies Matter
Enforce logical build order (e.g., build → test → deploy)
Prevent unnecessary execution after failures
Modularize workflows for better readability and debugging
Optimize CI time by parallelizing independent jobs
🛠️ Defining Job Dependencies with needs
Basic Structure Example
jobs:
build:
runs-on: ubuntu-latest
steps:
run: npm run build
test:
needs: build
runs-on: ubuntu-latest
steps:
run: npm run test
deploy:
needs: test
runs-on: ubuntu-latest
steps:
run: npm run deploy
Parallel + Sequential Execution
→ Jobs without needs run in parallel
→ Jobs with needs wait for dependencies to complete
Handling Failures Gracefully
→ Use continue-on-error: true for soft dependencies
→ Combine with if: conditions for dynamic control
🧪 Real-World Use Cases:
Run linting and unit tests after build
Deploy only if tests pass
Trigger security scans post-deployment
Chain Playwright tests after environment setup
