我在新的Vue.js项目上运行的测试期间收到警告。组件在模板中将路由器用作<router-link>
或以编程方式this.$router.push('/');
测试正在通过,但记录了这些警告:
ERROR LOG: '[Vue warn]: Error in render: "TypeError: Cannot read property 'resolve' of undefined"
found in
---> <RouterLink>
<Root>'
我正在使用Vue2,该项目基于cli工具生成的webpack项目。
我的单元测试index.js:
import Vue from 'vue';
import VueNativeSock from 'vue-native-websocket';
import Router from 'vue-router';
Vue.use(Router);
Vue.use(VueNativeSock, process.env.WEBSOCKET_ADDR, { format: 'json', reconnection: true });
Vue.config.productionTip = false;
const testsContext = require.context('./specs', true, /\.spec$/);
testsContext.keys().forEach(testsContext);
const srcContext = require.context('../../src', true, /^\.\/(?!main(\.js)?$)/);
srcContext.keys().forEach(srcContext);
我的main.js:
import Vue from 'vue';
import VueNativeSock from 'vue-native-websocket';
import VueHead from 'vue-head';
import App from './App';
import router from './router';
Vue.config.productionTip = process.env.NODE_ENV === 'production';
Vue.use(VueNativeSock, process.env.WEBSOCKET_ADDR, { format: 'json', reconnection: true });
Vue.use(VueHead);
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
template: '<App/>',
components: { App },
head: {
link: [
{ rel: 'icon', href: '/static/favicon-32x32.png', sizes: '32x32', type: 'image/png' },
],
},
});
任何想法,我都缺少让这些警告消失?
基本测试可能如下所示:
import Vue from 'vue';
import ViewDTCs from '@/components/ViewDTCs';
describe('ViewDTCs.vue', () => {
const Constructor = Vue.extend(ViewDTCs);
const vm = new Constructor().$mount();
ViewDTCs.$socket = new WebSocket(process.env.WEBSOCKET_ADDR);
it('has a created hook', () => {
expect(typeof ViewDTCs.created).to.equal('function');
});
it('should render page', () => {
expect(vm.$el.textContent).to.contain('Retrieving DTCs');
});
});

您的路线可能无法在测试环境中的任何位置进行设置。如果您正在使用Karma和Avoriaz或Vue Test Utils,我已经能够测试包含以下路线的组件:
import { mount } from 'vue-test-utils'
import router from 'src/router' // path to your router
import MyComponent from 'src/components/MyComponent'
describe('MyComponent.vue', () => {
let wrapper
beforeEach(() => {
wrapper = mount(MyComponent, {
router: router
})
})
it('has a created hook', () => {
expect(typeof wrapper.created).to.equal('function')
})
...
})
