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

# .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

// 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

// 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

// 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

// 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

# 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

Resources

Next Steps

Proceed to gamma-deploy-integration for deployment workflows.
