Question

与Dispatcher not registering callbacks in jest unit tests非常相似

我在实体店有dispatcher.register。在我的jest单元测试中，模拟调度程序没有注册任何回调。我在这里错过了什么吗？请告诉我..

describe(“Simple store tests",function(){
    var actionTypes = require('../../constants/actionTypes');
    var AppDispatcher, simpleStore, callback;
//mock action
    var getProjects = {actionType: actionTypes.actions.GET_PROJECTS};
//prepare
    AppDispatcher = require('../../dispatcher/AppDispatcher');
    simpleStore = require('../simpleStore');
    var simpleActions = require('../../actions/simpleActions');

//callback = AppDispatcher.register.mock.calls[0][0];       //this one fails

    it('should initialize with no projects in the list',function(){
        var projects = simpleActions.getProjects();
        console.log(AppDispatcher.register.mock.calls.length); *//this comes back as zero*
    })

})

你有没有告诉开玩笑不要嘲笑你的商店？此外，如果您在商店中使用object-assign，您也应该开玩笑说不要嘲笑它。

在第一次调用描述之前，在测试的顶部添加这些行 - 希望能够做到这一点：

jest.dontMock('../simpleStore');
jest.dontMock('object-assign'); // only if using object-assign

describe('simple store tests', function() {
    // rest of your code as before
});

希望这有帮助。

Dispatcher没有在jest单元测试中注册回调
