# PostHog CI Integration

## Overview
Set up CI/CD pipelines for PostHog integrations with automated testing.

## Prerequisites
- GitHub repository with Actions enabled
- PostHog test API key
- npm/pnpm project configured

## Instructions

### Step 1: Create GitHub Actions Workflow
Create `.github/workflows/posthog-integration.yml`:

```yaml
name: PostHog Integration Tests

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

env:
  POSTHOG_API_KEY: ${{ secrets.POSTHOG_API_KEY }}

jobs:
  test:
    runs-on: ubuntu-latest
    env:
      POSTHOG_API_KEY: ${{ secrets.POSTHOG_API_KEY }}
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'
      - run: npm ci
      - run: npm test -- --coverage
      - run: npm run test:integration
```

### Step 2: Configure Secrets
```bash
gh secret set POSTHOG_API_KEY --body "sk_test_***"
```

### Step 3: Add Integration Tests
```typescript
describe('PostHog Integration', () => {
  it.skipIf(!process.env.POSTHOG_API_KEY)('should connect', async () => {
    const client = getPostHogClient();
    const result = await client.healthCheck();
    expect(result.status).toBe('ok');
  });
});
```

## Output
- Automated test pipeline
- PR checks configured
- Coverage reports uploaded
- Release workflow ready

## Error Handling
| Issue | Cause | Solution |
|-------|-------|----------|
| Secret not found | Missing configuration | Add secret via `gh secret set` |
| Tests timeout | Network issues | Increase timeout or mock |
| Auth failures | Invalid key | Check secret value |

## Examples

### Release Workflow
```yaml
on:
  push:
    tags: ['v*']

jobs:
  release:
    runs-on: ubuntu-latest
    env:
      POSTHOG_API_KEY: ${{ secrets.POSTHOG_API_KEY_PROD }}
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
      - run: npm ci
      - name: Verify PostHog production readiness
        run: npm run test:integration
      - run: npm run build
      - run: npm publish
```

### Branch Protection
```yaml
required_status_checks:
  - "test"
  - "posthog-integration"
```
