Answer: Locators are how Playwright finds elements on a page at any moment, and they are the center of its auto-waiting and retry behavior. Prefer user-facing locators such as getByRole, getByText, getByLabel, getByPlaceholder, getByAltText, getByTitle, and getByTestId.

Choosing a locator

getByRole is the recommended starting point because it uses explicit and implicit accessibility attributes. For a button labeled "Sign in", that is page.getByRole('button', { name: 'Sign in' }). getByTestId looks at a data-testid attribute by default, and that attribute name can be configured.

The class in source

The Locator constructor takes a frame, a selector string, and options. Options such as hasText, has, and hasNot are added onto _selector. A nested has or hasNot locator must belong to the same frame.
