assertSame()

# assertSame()
>[info] ## assertSame(mixed $expected, mixed $actual[, string $message = ''])
当两个变量 `$expected` 和 `$actual` 的值与类型不完全相同时报告错误，错误讯息由 `$message` 指定。
`assertNotSame()` 是与之相反的断言，接受相同的参数。
`assertAttributeSame()` 和 `assertAttributeNotSame()` 是便捷包装(convenience wrapper)，以某个类或对象的某个 `public`、`protected` 或 `private` 属性作为实际值来进行比较。
