playwright.expect.expect_to_have_class
playwright.expect.expect_to_have_class(loc, class_, *, timeout=None)Expect a CSS class value is found.
This method wraps Playwright's Locator expectation to_have_class() method. However, Playwright does not have an easy method to check for individual class values within the elements class value.
This method will insert the class value into a regex pattern to check for the class value within the class attribute according to word boundaries or the start/end of the class string.
