Learning Objectives

After completing this lesson, you will be able to:

• Understand the Page Object Model (POM) design pattern.

• Build reusable page classes.

• Separate test logic from UI locators.

• Improve maintainability and readability.

• Create a scalable Playwright automation framework.

Introduction

As automation projects grow, keeping all locators and test logic in a single test file quickly becomes difficult to manage.

Consider a login test:

page.locator("#username").fill("admin");
page.locator("#password").fill("Password123");
page.locator("#loginButton").click();

This works for a small project.

But imagine hundreds of tests using the same locators. If the login button ID changes, every test must be updated.

The Page Object Model (POM) solves this by encapsulating page-specific locators and actions into dedicated Java classes.

What is the Page Object Model?

The Page Object Model is a design pattern in which each web page is represented by a Java class.

For example:

Login Page
    ↓
LoginPage.java

Dashboard Page
    ↓
DashboardPage.java

Orders Page
    ↓
OrdersPage.java

Each class contains:

• Page locators

• Page actions

• Helper methods

Your test classes then interact with these page objects instead of directly using locators.

Benefits of POM

• Improved code readability.

• Reduced code duplication.

• Easier maintenance.

• Better separation of concerns.

• Simpler onboarding for new team members.

• Scalable framework design.

Recommended Project Structure

src
├── main
│   ├── pages
│   │   ├── LoginPage.java
│   │   ├── DashboardPage.java
│   │   └── OrdersPage.java
│   ├── base
│   │   └── BasePage.java
│   └── utils
│       ├── ConfigReader.java
│       └── ScreenshotUtil.java
│
└── test
    ├── LoginTests.java
    ├── DashboardTests.java
    └── OrderTests.java

This structure keeps responsibilities clear and makes the framework easier to extend.

Creating a Login Page Object

Example:

public class LoginPage {

    private final Page page;

    public LoginPage(Page page) {
        this.page = page;
    }

    public void login(String username, String password) {
        page.getByLabel("Username").fill(username);
        page.getByLabel("Password").fill(password);
        page.getByRole(AriaRole.BUTTON,
            new Page.GetByRoleOptions().setName("Login")).click();
    }
}

Notice how the test no longer needs to know anything about the page's locators.

Writing the Test

LoginPage loginPage = new LoginPage(page);

loginPage.login("admin", "Password123");

The test reads almost like plain English, making it easier to understand and maintain.

Why This Matters

Imagine your application's login button changes from:

#loginButton

to:

#btnLogin

Without POM, you may need to update dozens of test files.

With POM, you update the locator in one place.

Every test continues to work.

Real-World Scenario

Suppose you're testing an e-commerce application with pages such as:

• Login

• Home

• Product

• Cart

• Checkout

• Order History

Each page becomes its own Java class, and tests simply call methods like:

• login()

• searchProduct()

• addToCart()

• checkout()

This approach creates reusable building blocks for your automation suite.

Best Practices

• One page = one page object.

• Keep assertions in test classes unless they are tightly coupled to page behavior.

• Use meaningful method names like login(), addProductToCart(), and logout().

• Avoid exposing raw locators to test classes.

• Reuse page objects wherever possible.

Common Mistakes

Putting Test Logic Inside Page Objects

A page object should model the page, not the test scenario.

Duplicating Locators

Store each locator in one place to reduce maintenance.

Creating Large "God" Page Objects

Keep classes focused on a single page or component rather than combining unrelated functionality.

Practice Exercise

Create a small framework with:

1. LoginPage

2. DashboardPage

3. LoginTest

Implement a login() method in the page object and verify successful navigation to the dashboard.

Interview Questions

1. What is the Page Object Model?

2. Why is POM preferred in automation frameworks?

3. What problems does POM solve?

4. Should assertions be placed inside page objects?

5. How does POM improve maintainability?

6. What is the difference between a Page Object and a test class?

FAQs

Is POM mandatory?

No, but it is considered a best practice for medium and large automation projects.

Can POM be used with Playwright?

Yes. Playwright works very well with the Page Object Model, especially for enterprise-scale automation.

Does POM reduce code duplication?

Yes. Common locators and actions are centralized, making tests cleaner and easier to maintain.

Summary

In this lesson, you learned:

• What the Page Object Model is.

• Why it is widely used in automation.

• How to create page classes.

• How to separate UI interactions from test logic.

• Best practices for building scalable Playwright frameworks.

POM is one of the most important concepts for any automation engineer. Once you master it, you'll be well prepared to build maintainable, production-ready automation frameworks.
