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.
