# Gamma CI Integration

## Overview

Set up continuous integration for Gamma-powered applications with automated testing and deployment.

## Prerequisites

- GitHub repository with Actions enabled
- Gamma test API key
- npm/pnpm project configured

## Instructions

### Step 1: Create GitHub Actions Workflow

```yaml
# .github/workflows/gamma-ci.yml
name: Gamma CI

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

env:
  GAMMA_API_KEY: ${{ secrets.GAMMA_API_KEY }}

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'

      - name: Install dependencies
        run: npm ci

      - name: Run unit tests
        run: npm test

      - name: Run Gamma integration tests
        run: npm run test:gamma
        env:
          GAMMA_MOCK: ${{ github.event_name == 'pull_request' }}

      - name: Upload coverage
        uses: codecov/codecov-action@v4
        with:
          files: ./coverage/lcov.info
```

### Step 2: Create Test Scripts

```json
// package.json
{
  "scripts": {
    "test": "vitest run",
    "test:gamma": "vitest run --config vitest.gamma.config.ts",
    "test:gamma:live": "GAMMA_MOCK=false vitest run --config vitest.gamma.config.ts"
  }
}
```

### Step 3: Gamma Test Configuration

```typescript
// vitest.gamma.config.ts
import { defineConfig } from 'vitest/config';

export default defineConfig({
  test: {
    include: ['tests/gamma/**/*.test.ts'],
    testTimeout: 60000, // Gamma API can be slow  # 60000: 1 minute in ms
    hookTimeout: 30000,  # 30000: 30 seconds in ms
    setupFiles: ['./tests/gamma/setup.ts'],
  },
});
```

### Step 4: Test Setup with Mocking

```typescript
// tests/gamma/setup.ts
import { beforeAll } from 'vitest';
import { createGammaClient, type GammaClient } from '../../src/client';

const useMock = process.env.GAMMA_MOCK === 'true';

export let gamma: ReturnType<typeof createGammaClient>;

beforeAll(() => {
  if (useMock) {
    gamma = createMockGammaClient();
  } else {
    gamma = createGammaClient({
      apiKey: process.env.GAMMA_API_KEY!,
    });
  }
});

function createMockGammaClient() {
  return {
    generate: vi.fn().mockResolvedValue({ generationId: 'mock-gen-id' }),
    poll: vi.fn().mockResolvedValue({
      status: 'completed',
      gammaUrl: 'https://gamma.app/docs/mock-test',
      exportUrl: 'https://export.gamma.app/mock.pdf',
      creditsUsed: 10,
    }),
    listThemes: vi.fn().mockResolvedValue([{ id: 'theme_1', name: 'Default' }]),
    listFolders: vi.fn().mockResolvedValue([]),
  };
}
```

### Step 5: Integration Test Example

```typescript
// tests/gamma/generation.test.ts
import { describe, it, expect } from 'vitest';
import { gamma } from './setup';

describe('Gamma Generation', () => {
  it('should start a generation', async () => {
    const result = await gamma.generate({
      content: 'CI Test: 1-card overview of testing',
      outputFormat: 'presentation',
    });

    expect(result.generationId).toBeDefined();
  });

  it('should list workspace themes', async () => {
    const themes = await gamma.listThemes();
    expect(Array.isArray(themes)).toBe(true);
  });
});
```

### Step 6: Add Secrets to GitHub

```bash
# Using GitHub CLI
gh secret set GAMMA_API_KEY --body "your-test-api-key"

# Verify secrets
gh secret list
```

## Output

- Automated test pipeline running on push/PR
- Mock mode for PR checks (no API calls)
- Live integration tests on main branch
- Coverage reports uploaded

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| Secret not found | Missing GitHub secret | Add GAMMA_API_KEY secret |
| Test timeout | Slow API response | Increase testTimeout |
| Mock mismatch | Mock out of sync | Update mock responses |
| Rate limit in CI | Too many test runs | Use mock mode for PRs |
