1 backdrop_web_test_case.php protected BackdropTestCase::assert($status, $message = '', $group = 'Other', array $caller = NULL)

Internal helper: stores the assert.


$status: Can be 'pass', 'fail', 'exception'. TRUE is a synonym for 'pass', FALSE for 'fail'.

$message: The message string.

$group: Which group this assert belongs to.

$caller: By default, the assert comes from a function whose name starts with 'test'. Instead, you can specify where this assert originates from by passing in an associative array as $caller. Key 'file' is the name of the source file, 'line' is the line number and 'function' is the caller function itself.

Return value

bool: TRUE if the assertion passed and FALSE if it failed.
