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.

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 by creating a higher-level API which suits your application and simplify maintenance by capturing element selectors in one place and create reusable code to avoid repetition.

Implementation

Page object models wrap over a Playwright Page.

// models/SearchPage.java
package models;

import com.microsoft.playwright;

public class SearchPage {
private final Page page;
private final Locator searchTermInput;

public SearchPage(Page page) {
this.page = page;
this.searchTermInput = page.locator("[aria-label='Enter your search term']");
}

public void navigate() {
page.navigate("https://bing.com");
}

public void search(String text) {
searchTermInput.fill(text);
searchTermInput.press("Enter");
}
}

Page objects can then be used inside a test.

import models.SearchPage;
import com.microsoft.playwright.*;
...

// In the test
Page page = browser.newPage();
SearchPage searchPage = new SearchPage(page);
searchPage.navigate();
searchPage.search("search query");
