message <string> | <Error>

测试 actual 和 expected 参数之间的深度相等性。 “深度”相等意味着子对象的可枚举“自身”属性也会按照以下规则递归地进行评估。

【Tests for deep equality between the actual and expected parameters. "Deep" equality means that the enumerable "own" properties of child objects are recursively evaluated also by the following rules.】
