What you will learn

  • Email verification is mandatory for most production APIs — assert the flow: register → verification email → confirm link → active account
  • Duplicate email on register = 409 Conflict with an email-exists error code — never 200 with a silent no-op
  • Password policy is server-enforced (length, complexity, breach check) — test rejection with weak passwords, never trust client-side checks

Description

Register a new user account with validation.

Test Scenario

const response = await request.post('/api/v1/auth/register', {
  data: {
    email: 'new@test.com',
    password: 'StrongPass123!',
    name: 'New User'
  }
});
expect(response.status()).toBe(201);
Endpoint/api/v1/auth/register

Testing Tips

  • •Validate email format
  • •Check password requirements
  • •Handle duplicate email
// Playwright API Testing - REST
import { test, expect } from '@playwright/test';


test('REST API request', async ({ request }) => {
  const response = await request.get('/api/v1/resource');


  expect(response.ok()).toBeTruthy();
  expect(response.status()).toBe(200);


  const data = await response.json();
  expect(data).toBeDefined();
});
