JSdom 11.12.0 - 如何模拟 localStorage? [英] JSDom 11.12.0 - how to mock localStorage?

问题描述

自从最新版本的 JSDom 发布以来，我无法再模拟 localStorage.

Since the latest release of JSDom, I'm not able to mock localStorage anymore.

我尝试了以下方法:

1. Object.defineProperty(window, 'localStorage', {value: LocalStorageMock})
2. window.localStorage = LocalStorageMock;
3. jest.spyOn(window.localStorage, 'setItem')

这些方法中的任何一个都不适合我，我总是得到原始的 localStorage.

Any of those methods not worked for me, I get always the original localStorage.

推荐答案

setItemSpy = jest.spyOn(Storage.prototype, 'setItem'); 对我有用.
