protected function TestBase::assertNull in Drupal 8
Check to see if a value is NULL.
Parameters
$value: The value on which the assertion is to be done.
$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.
$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.
Return value
TRUE if the assertion succeeded, FALSE otherwise.
