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

版本历史

版本	变更
v9.0.0	Enumerable symbol properties are now compared.
v9.0.0	The `NaN` is now compared using the SameValueZero comparison.
v8.5.0	The `Error` names and messages are now properly compared
v8.0.0	The `Set` and `Map` content is also compared
v6.4.0, v4.7.1	Typed array slices are handled correctly now.
v6.1.0	Objects with circular references can be used as inputs now.
v5.10.1, v4.4.3	Handle non-`Uint8Array` typed arrays correctly.
v1.2.0	新增于: v1.2.0

actual <any>
expected <any>
message <string> | <Error>

测试 actual 参数和 expected 参数之间的深度相等。深度相等意味着子对象的可枚举的自身属性也通过以下规则进行递归计算。

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.
