The Page Object Model (POM) is a popular design
pattern in test automation, used to enhance code
maintainability and readability. In the context of
Playwright, an open-source end-to-end testing
framework, POM helps in organizing test scripts by
encapsulating page elements and actions into reusable
classes.
POM Structure Overview
•
Page Classes
: In POM, each webpage or component is represented
as a class. For example, you could have classes like LoginPage,
HomePage, or ProductPage. These classes define locators and
methods that interact with elements on that specific page.
•
Locators
: The elements on a page (like buttons, text fields, or
dropdowns) are defined as properties within the page class.
Playwright’s locator strategy (e.g., page.locator('selector')) is used tofind these elements.

Page Methods
: The page class also encapsulates actions like
clicking buttons, filling out forms, or retrieving text. These
methods make the test scripts more readable by abstracting
complex interactions into intuitive function calls. For instance, a
method like login(username, password) might wrap the actions of
entering credentials and clicking a submit button.
•
Test Scripts
: Test scripts then call the methods defined in the page
classes. This approach reduces redundancy because the element
locators and methods are maintained in a single place, rather than
being scattered across multiple test scripts.

Benefits of POM in Playwright
•
Reusability
: Common actions or sequences can be reused across
different test cases.
•
Maintainability
: Changes in the UI (like updated selectors) are
easier to manage since they only need to be updated in one place—
the relevant page class.
•
Readability
: By separating test logic from UI interaction, test
scripts become more straightforward and easier to understand.

In Playwright, adopting the POM structure is crucial
for scalable, maintainable, and clean test automation,
especially for large-scale projects with complex user
interfaces.
