class: PageAssertions

• langs: java, python

The [PageAssertions] class provides assertion methods that can be used to make assertions about the [Page] state in the tests. A new instance of [LocatorAssertions] is created by calling [method: PlaywrightAssertions.assertThatPage]:

...
import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat;

public class TestPage {
  ...
  @Test
  void navigatesToLoginPage() {
    ...
    page.click("#login");
    assertThat(page).hasURL(Pattern.compile(".*/login"));
  }
}

method: PageAssertions.not

• langs: java

• returns: <[PageAssertions]>

Makes the assertion check for the opposite condition. For example, this code tests that the page URL doesn't contain "error":

assertThat(page).not().hasURL("error");
