Javascript Sinon存根不适用于导出的函数
Sinon似乎没有从导入的文件中删除方法。这与导出常量有关吗 我在console.log中看到“已接收原始消息” Main.jsJavascript Sinon存根不适用于导出的函数,javascript,sinon,sinon-chai,Javascript,Sinon,Sinon Chai,Sinon似乎没有从导入的文件中删除方法。这与导出常量有关吗 我在console.log中看到“已接收原始消息” Main.js import * as otherActions from 'filters/actions/Other.actions'; describe('filter actions', () => { it('should log STUBBED MESSAGE', () => { sinon.stub(otherActions,

出现此问题的原因是,当在模块上下文中引用时,您正在导出模块中存根函数。当从模块内部引用它时,您不是存根。有很多方法可以解决这个问题,但我认为所有这些都需要您稍微更改一下生产代码 一项建议是: Other.actions.js
export const logger = { message: () => console.log("ORIGINAL MESSAGE") };
Main.js
import * as otherActions from 'filters/actions/Other.actions';
...
sinon.stub(otherActions.logger, 'message')
.callsFake(m => console.log('STUBBED Message'));
重要的是,您要在测试模块可用的上下文中创建存根
另一个一般性意见是,通常情况下,您不希望在正在测试的模块中模拟或存根函数或方法。通常,单元测试单元指的是一个模块。因此,如果您发现需要在正在测试的同一模块中删除某些内容,那么我建议您的模块边界不正确。您使用的是哪一版本的sinon?我使用的是5.0.10版
