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.
