assertInstanceOf()

1	`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.
