常见的想当然

Jest's expect(a).toEqual(b) and expect(a).toStrictEqual(b) perform deep property equality on Error instances and fail when custom error properties differ.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• expect(errA).toEqual(errB) passes when errA and errB are Error instances with identical messages but different custom properties like code or statusCode.
• expect(errA).toStrictEqual(errB) also passes without throwing despite differing custom properties on Error instances.
• assert.notStrictEqual(errA.code, errB.code) verifies the custom properties are distinct.
