assert.deepStrictEqual(actual, expected[, message])


    测试 actualexpected 参数之间的深度相等。 "深度"相等意味着子对象的可枚举"自有"属性也按照以下规则递归地评估。

    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.
