protected function TestBase::assertNull in SimpleTest 8.3

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.
