assertSame()

assertSame()

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。
