# assertInternalType()
>[info] ## assertInternalType($expected, $actual[, $message = ''])
当 `$actual` 不是 `$expected` 所指明的类型时报告错误，错误讯息由 `$message` 指定。
`assertNotInternalType()` 是与之相反的断言，接受相同的参数。
`assertAttributeInternalType()` 和 `assertAttributeNotInternalType()` 是便捷包装(convenience wrapper)，可以应用于某个类或对象的某个 `public`、`protected` 或 `private` 属性。
