Page Object Models

Large test suites can be structured to optimize ease of authoring and maintenance. Page object models are one such approach to structure your test suite.

Introduction

A page object represents a part of your web application. An e-commerce web application might have a home page, a listings page and a checkout page. Each of them can be represented by page object models.

Page objects simplify authoring. They create a higher-level API which suits your application.

Page objects simplify maintenance. They capture element selectors in one place and create reusable code to avoid repetition.

Implementation

Page object models wrap over a Playwright page.

// models/Search.js
class SearchPage {
  constructor(page) {
    this.page = page;
  }
  async navigate() {
    await this.page.goto('https://bing.com');
  }
  async search(text) {
    await this.page.fill('[aria-label="Enter your search term"]', text);
    await this.page.keyboard.press('Enter');
  }
}
module.exports = { SearchPage };

Page objects can then be used inside a test.

// search.spec.js
const { SearchPage } = require('./models/Search');

// In the test
const page = await browser.newPage();
const searchPage = new SearchPage(page);
await searchPage.navigate();
await searchPage.search('search query');
