What is the process of implementing the Page Object Model with Playwright in testing?


Using Page Object Model with Playwright

To implement the Page Object Model (POM) with Playwright, you'll need to create a class for each page of your application that you want to test. These classes should include locators and helper methods specific to each page.

Here's an example of how you might set up a class for a user page:

class UserPage {
  // Define your locators here
  // Define your helper methods here

You'll also need to declare the types of your fixtures using TypeScript. You can then export these fixtures from @playwright/test and extend them in your tests.

import { test, expect } from '@playwright/test';

test('my test', async ({ page }) => {
  // Use your page object here

Remember, each test should be completely isolated from another test. This means each test should run independently with its own local storage, session storage, data, cookies, etc. This improves reproducibility, makes debugging easier, and prevents cascading test failures.

To avoid repetition, you can use before and after hooks. For example, you might use a before hook to navigate to a specific URL or log in to a part of your app before each test. This keeps your tests isolated, as no test relies on another.

test.beforeEach(async ({ page }) => {
  await page.goto('https://ray.run');

Don't worry about some duplication in your tests. If they're simple enough, a bit of repetition can actually make them clearer and easier to read and maintain. Happy testing!
