function AssertContentTrait::assertTitle

Pass if the page title is the given string.

Parameters

string $title: The string the title should be.

string $message: (optional) A message to display with the assertion. Do not translate messages: use \Drupal\Component\Render\FormattableMarkup to embed variables in the message text, not t(). If left blank, a default message will be displayed.

string $group: (optional) The group this message is in, which is displayed in a column in test output. Use 'Debug' to indicate this is debugging output. Do not translate this string. Defaults to 'Other'; most tests do not override this default.
