Use Faker.js for Generating Dynamic Test Data

import { faker } from '@faker-js/faker';

const randomUser = {
 firstName: faker.person.firstName(),
 lastName: faker.person.lastName(),
 email: faker.internet.email(),
 password: faker.internet.password(),
};

// Fill out a registration form
await page.fill('#first-name', randomUser.firstName);
await page.fill('#last-name', randomUser.lastName);
await page.fill('#email', randomUser.email);
await page.fill('#password', randomUser.password);
await page.click('#register-button');

// Assert successful registration
await expect(page.locator('.success-msg')).toHaveText('Registration successful!');

Use Case:

Testing forms, user flows, or APIs with unique data to avoid collisions.
Simulating edge cases like long names or special characters.

Why It’s Great:

Keeps your tests flexible and realistic.
Reduces the risk of hard-coded test data causing false positives.
Covers scenarios your static data might miss (e.g., generating 50+ users for load testing).
