javascript - 开 Jest -mockReturnValue : Promise

Question

我是新人，我想模拟一个返回 Promise<boolean>. 的函数我这样做了:

service.changeBookingAsync = jest.fn().mockReturnValue(boolean);

但是我收到了这个错误:

error TS2693: 'boolean' only refers to a type, but is being used as a value here.

语法糖函数将是这样的:

jest.fn().mockResolvedValue(value);
