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

版本历史

版本	变更
v9.0.0	现在比较可枚举的符号属性。
v9.0.0	现在使用 SameValueZero 比较来比较 `NaN`。
v8.5.0
v8.0.0
v6.4.0, v4.7.1	现在可以正确地处理类型化数组切片。
v6.1.0	现在可以将具有循环引用的对象用作输入。
v5.10.1, v4.4.3	正确地处理非 `Uint8Array` 类型的数组。
v1.2.0	新增于: v1.2.0

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

测试 actual 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"自有"属性也按照以下规则递归地评估。

History

Version	Changes
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	Added in: v1.2.0

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

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.
