How to Use

For First-Time Setup

1. Install Prerequisites:

   # Install Docker (if not already installed)
   # macOS: Docker Desktop
   # Linux: docker.io package
   # Windows: Docker Desktop
   
   # Install act
   # macOS
   brew install act
   
   # Linux
   curl -s https://raw.githubusercontent.com/nektos/act/master/install.sh | sudo bash
   
   # Windows
   choco install act-cli
   

2. Run Diagnostics:

   ./scripts/diagnose-workflows.sh
   

3. Fix Reported Issues: Follow the fix suggestions in the diagnostic output.

4. Test Workflows:

   ./scripts/test-workflows.sh
   

For Daily Development

Before Every Commit:

npm run lint
npm run build

Before Every Push:

./scripts/diagnose-workflows.sh
act -j lint -j build

Before Creating PR:

./scripts/test-workflows.sh
# Select option 7 (full CI pipeline)

When Workflow Fails on GitHub:

# Run the same job locally
act -j <job-name> -v

# Or use interactive menu
./scripts/test-workflows.sh

Workflow Coverage

Workflows That Can Be Tested

✅ ci.yml - Full Support

All jobs can be tested locally:

• prisma-check - Validates Prisma setup
• lint - Runs ESLint
• build - Tests production build
• test-e2e - Runs Playwright tests

Test with:

act push
# or individually
act -j prisma-check
act -j lint
act -j build
act -j test-e2e

⚠️ code-review.yml - Limited Support

Can be tested but requires PR context:

act pull_request -W .github/workflows/code-review.yml

Use custom event payload for better simulation.

⚠️ auto-merge.yml - Limited Support

Requires GitHub API access, may not work fully locally.

⚠️ pr-management.yml - Limited Support

Can be tested with custom event payload:

act pull_request -W .github/workflows/pr-management.yml -e event.json

Known Limitations

1. GitHub API Calls: Workflows that use github.rest.* APIs may not work fully with act.

2. Secrets: Some workflows may require secrets. Create .secrets file (don't commit!).

3. Docker Resources: E2E tests may require more Docker memory (8GB+).

4. Browser Tests: Playwright tests may behave differently in Docker environment.

Troubleshooting Guide

Issue: Act Not Found

Symptoms:

bash: act: command not found

Solution: Install act:

• macOS: brew install act
• Linux: curl -s https://raw.githubusercontent.com/nektos/act/master/install.sh | sudo bash
• Windows: choco install act-cli

Issue: Docker Not Running

Symptoms:

Cannot connect to the Docker daemon

Solution: Start Docker Desktop or Docker daemon.

Issue: Missing Dependencies

Symptoms:

npm ERR! missing: @prisma/client

Solution:

npm install

Issue: Prisma Schema Not Found

Symptoms:

Error: Could not find Prisma schema

Solution:

npx prisma init
# Edit prisma/schema.prisma
npx prisma generate

Issue: Docker Out of Memory

Symptoms:

Error: Process completed with exit code 137

Solution: Open Docker Desktop → Settings → Resources → Increase Memory to 8GB+

Issue: Workflow Passes Locally but Fails on GitHub

Possible Causes:

1. package-lock.json not committed
2. Environment differences
3. Secrets not available on GitHub
4. Different Node version

Solution:

# Ensure lockfile is committed
git add package-lock.json
git commit -m "Update package-lock.json"

# Test with exact CI environment
act -P ubuntu-latest=ghcr.io/catthehacker/ubuntu:act-latest
