Test your email flows end-to-end using Playwright and Reloop's API.

## Approach

Use Reloop's API to verify that emails were sent correctly during your E2E tests. Instead of checking actual inboxes, query the Reloop API to confirm emails were delivered.

## Setup

```bash
npm install @playwright/test reloop
```

## Example Test

```typescript
import { test, expect } from '@playwright/test';
import { Reloop } from 'reloop';

const reloop = new Reloop(process.env.RELOOP_API_KEY);

test('signup sends welcome email', async ({ page }) => {
  // Trigger the signup flow
  await page.goto('/signup');
  await page.fill('[name="email"]', 'test@example.com');
  await page.click('button[type="submit"]');

  // Wait for the email to be sent
  await page.waitForTimeout(3000);

  // Verify via Reloop API
  const { data } = await reloop.emails.list();
  const welcomeEmail = data?.data?.find(
    (e) => e.to?.includes('test@example.com') && e.subject?.includes('Welcome')
  );

  expect(welcomeEmail).toBeDefined();
  expect(welcomeEmail?.last_event).toBe('delivered');
});
```

<Tip>
Use [testing email addresses](/docs/guides/testing-email-addresses) to avoid sending real emails during tests.
