3. 11.x core/tests/Drupal/FunctionalJavascriptTests/JSWebAssert.php \Drupal\FunctionalJavascriptTests\JSWebAssert::assertVisibleInViewport()

Test that a node, or its specific corner, is visible in the viewport.

Note: Always set the viewport size. This can be done with a PhantomJS startup parameter or in your test with \Behat\Mink\Session->resizeWindow(). Drupal CI Javascript tests by default use a viewport of 1024x768px.

Parameters

string $selector_type: The element selector type (CSS, XPath).

string|array $selector: The element selector. Note: the first found element is used.

bool|string $corner: (Optional) The corner to test: topLeft, topRight, bottomRight, bottomLeft. Or FALSE to check the complete element (default).

string $message: (optional) A message for the exception.

Throws

\Behat\Mink\Exception\ElementHtmlException When the element doesn't exist.

\Behat\Mink\Exception\ElementNotFoundException When the element is not visible in the viewport.
