jestjs - 开玩笑的手动模拟不起作用

Question

我正在尝试为自定义模块进行手动模拟 ->help.js 我已经创建了手动模拟 |-models | |-模拟 |-help.js |help.js |test.js

嘲笑 help.js 之类的功能

 jest.mock('./help', () => {
   return {
     add: jest.fn(() => jest.fn()),
     delete: jest.fn(() => jest.fn()),
     toggle: jest.fn(() => jest.fn())
   };

我正在尝试在 test.js 中使用模拟模块，例如

jest.mock('./_mocks_/help');
const help =require()
test('add',()=>{
expect(help.add).toHaveBeenCalledWith({
      type: 'test',
        });
})

它再次调用主实现模块而不是模拟模块。请帮帮我。我是开玩笑的新手 在此先感谢
