Installation

bun add --dev @go-corp/test-framework

Quick Start

Basic Setup

// test/setup.ts
import { setupCloudflareWorkerTests } from '@go-corp/test-framework'

// Sets up console mocking and required environment variables
setupCloudflareWorkerTests()

Simple Request Testing

import { requestWithCookies, postJSON } from '@go-corp/test-framework'
import app from '../src/app'

test('user authentication flow', async () => {
  // All requests automatically persist cookies
  const { json: user } = await postJSON(app, '/api/auth/sign-in', {
    body: { email: '[email protected]', password: 'password' }
  })
  
  // Session cookie is automatically included in subsequent requests
  const { json: profile } = await requestJSON(app, '/api/profile', {
    method: 'GET'
  }, { expected: 200 })
  
  expect(profile.email).toBe('[email protected]')
})

Modern API Usage

// Modern setup with enhanced features
import { 
  setupTestFramework, 
  TestDataFactory,
  createHttpTestClient,
  dbTest,
  factoryTest 
} from '@go-corp/test-framework'
import app from '../src/app'

// Configure test framework
setupTestFramework({
  app,
  database: 'sqlite',
  isolation: 'test',
  autoCleanup: true
})

// Database test with automatic cleanup
dbTest('user creation with database', async (db) => {
  const factory = new TestDataFactory()
  const userData = factory.user()
  
  // Insert user into database
  await db.insert(users).values(userData)
  
  // Test API endpoint
  const client = createHttpTestClient(app)
  const { response, json } = await client.getJSON(`/api/users/${userData.id}`)
  
  expect(response.status).toBe(200)
  expect(json.email).toBe(userData.email)
})

// Factory test with seeded data
factoryTest('consistent test data', async (factory) => {
  const user1 = factory.user()
  const user2 = factory.user()
  
  // Same seed produces consistent data across test runs
  expect(user1.id).toBeDefined()
  expect(user2.id).toBeDefined()
  expect(user1.id).not.toBe(user2.id)
}, 12345) // Custom seed

Core Testing Utilities

Request Helpers

requestWithCookies(app, path, init?, jarKey?)

Makes a request with automatic cookie persistence across test requests.

import { requestWithCookies, resetCookies } from '@go-corp/test-framework'

// Start with clean session
resetCookies()

// Login request sets session cookie
const loginRes = await requestWithCookies(app, '/api/auth/login', {
  method: 'POST',
  headers: { 'content-type': 'application/json' },
  body: JSON.stringify({ username: 'test', password: 'pass' })
})

// Subsequent requests automatically include session cookie
const profileRes = await requestWithCookies(app, '/api/profile')

requestJSON(app, path, init, options?)

Request helper that automatically parses JSON and validates status codes.

// Expect 200 status (default)
const { res, json } = await requestJSON(app, '/api/users', {
  method: 'GET'
})

// Expect specific status
const { json: error } = await requestJSON(app, '/api/invalid', {
  method: 'GET'
}, { expected: 404 })

// Accept multiple status codes
const { json } = await requestJSON(app, '/api/endpoint', {
  method: 'POST',
  body: JSON.stringify(data)
}, { expected: [200, 201] })

postJSON(app, path, options?)

Convenience wrapper for POST requests with JSON body.

// Simple POST
const { json } = await postJSON(app, '/api/users', {
  body: { name: 'John', email: '[email protected]' }
})

// With status validation
const { json } = await postJSON(app, '/api/users', {
  body: { name: 'John' },
  expected: 201
})

Session Management

Multiple Test Sessions

Use different jarKey values to isolate test sessions:

import { requestWithCookies, resetCookies } from '@go-corp/test-framework'

test('concurrent user sessions', async () => {
  // User A login
  await postJSON(app, '/api/auth/login', {
    body: { username: 'userA' },
    jarKey: 'sessionA'
  })
  
  // User B login  
  await postJSON(app, '/api/auth/login', {
    body: { username: 'userB' },
    jarKey: 'sessionB'
  })
  
  // Each user sees their own profile
  const { json: profileA } = await requestJSON(app, '/api/profile', {}, {
    jarKey: 'sessionA'
  })
  const { json: profileB } = await requestJSON(app, '/api/profile', {}, {
    jarKey: 'sessionB'
  })
  
  expect(profileA.username).toBe('userA')
  expect(profileB.username).toBe('userB')
})

Test Context

Create isolated test contexts with automatic cleanup:

import { createTestContext } from '@go-corp/test-framework'

test('isolated test context', async () => {
  const ctx = createTestContext()
  
  // All requests use isolated cookie jar
  await ctx.postJSON(app, '/api/auth/login', {
    body: { username: 'test' }
  })
  
  const { json } = await ctx.requestJSON(app, '/api/profile', {})
  expect(json.username).toBe('test')
  
  // Clean up (optional, happens automatically)
  ctx.reset()
})

Email Testing

Test email functionality with built-in assertion helpers.

Basic Email Testing

import { 
  clearOutbox, 
  assertEmailSent, 
  extractVerificationLink 
} from '@go-corp/test-framework'

test('password reset flow', async () => {
  await clearOutbox(app)
  
  // Trigger password reset
  await postJSON(app, '/api/auth/reset-password', {
    body: { email: '[email protected]' }
  })
  
  // Assert email was sent
  const email = await assertEmailSent(app, '[email protected]')
  expect(email.subject).toContain('Password Reset')
  
  // Extract and use verification link
  const resetLink = extractVerificationLink(email)
  expect(resetLink).toBeTruthy()
  
  // Test the verification link
  const { json } = await requestJSON(app, resetLink!)
  expect(json.message).toBe('Reset link verified')
})

Advanced Email Testing

import { 
  getOutbox,
  getLastEmail,
  waitForEmail,
  extractOTPCode
} from '@go-corp/test-framework'

test('email verification with OTP', async () => {
  await clearOutbox(app)
  
  // Trigger account creation
  await postJSON(app, '/api/auth/register', {
    body: { email: '[email protected]' }
  })
  
  // Wait for email (useful for async operations)
  const email = await waitForEmail(app, '[email protected]', 3000)
  
  // Extract OTP code
  const otpCode = extractOTPCode(email)
  expect(otpCode).toBeTruthy()
  
  // Verify with OTP
  const { json } = await postJSON(app, '/api/auth/verify-otp', {
    body: { email: '[email protected]', code: otpCode }
  })
  
  expect(json.verified).toBe(true)
})

Test Environment Setup

Basic Setup

import { setupCloudflareWorkerTests } from '@go-corp/test-framework'

// Automatic setup with sensible defaults
setupCloudflareWorkerTests()

Custom Setup

import { setupTestEnvironment } from '@go-corp/test-framework'

setupTestEnvironment({
  mockConsole: true,
  consoleMethods: ['log', 'info', 'debug'],
  env: {
    API_KEY: 'test-key',
    DATABASE_URL: 'test-db'
  },
  cleanup: [
    () => {
      // Custom cleanup logic
    }
  ]
})

Environment Variables

import { ensureTestEnv, withTestEnv } from '@go-corp/test-framework'

// Ensure variables exist with defaults
ensureTestEnv({
  RESEND_API_KEY: 'test-key',
  NODE_ENV: 'test'
})

// Run test with specific environment
const testWithEnv = withTestEnv({
  FEATURE_FLAG: 'enabled'
}, async () => {
  // Test logic here
  const { json } = await requestJSON(app, '/api/feature')
  expect(json.enabled).toBe(true)
})

await testWithEnv()

Time Mocking

import { createTimeMock } from '@go-corp/test-framework'

test('time-sensitive operations', async () => {
  const mockTime = createTimeMock(new Date('2024-01-01'))
  mockTime.start()
  
  // Create token that expires in 1 hour
  const { json: token } = await postJSON(app, '/api/auth/token')
  
  // Advance time by 2 hours
  mockTime.advance(2 * 60 * 60 * 1000)
  
  // Token should now be expired
  const { json } = await requestJSON(app, '/api/auth/verify', {
    headers: { authorization: \`Bearer \${token.access_token}\` }
  }, { expected: 401 })
  
  expect(json.error).toBe('Token expired')
  
  mockTime.restore()
})

Utility Functions

Unique Data Generation

import { uniqueEmail, uniqueUsername } from '@go-corp/test-framework'

test('user creation', async () => {
  const email = uniqueEmail() // [email protected]
  const username = uniqueUsername() // user1
  
  await postJSON(app, '/api/users', {
    body: { email, username }
  })
})

Wait Utility

import { wait } from '@go-corp/test-framework'

test('async operations', async () => {
  // Trigger async operation
  await postJSON(app, '/api/process')
  
  // Wait for processing
  await wait(1000)
  
  // Check result
  const { json } = await requestJSON(app, '/api/status')
  expect(json.status).toBe('completed')
})
