Helper for assertUniqueText and assertNoUniqueText.

It is not recommended to call this function directly.

Parameters

string|\Drupal\Component\Render\MarkupInterface $text: Plain text to look for.

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. Defaults to 'Other'.

bool $be_unique: (optional) TRUE if this text should be found only once, FALSE if it should be found more than once. Defaults to FALSE.

Return value

bool TRUE on pass.
