assertInstanceOf() assertInstanceOf($expected, $actual[, $message = '']) Reports an error identified by $message if $actual is not an instance of $expected. assertNotInstanceOf() is the inverse of this assertion and takes the same arguments. assertAttributeInstanceOf() and assertAttributeNotInstanceOf() are convenience wrappers that can be applied to a public, protected, or private attribute of a class or object. Example A.29: Usage of assertInstanceOf() <?php use PHPUnit\Framework\TestCas
