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. 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.
Page object models wrap over a Playwright Page.
Page objects can then be used inside a test.
