Unit testing Vue.js Vuetify,使用Jest运行我的第一个单元测试的问题
这是我的第一个测试: 标题.spec.jsUnit testing Vue.js Vuetify,使用Jest运行我的第一个单元测试的问题,unit-testing,vue.js,jestjs,vuetify.js,Unit Testing,Vue.js,Jestjs,Vuetify.js,这是我的第一个测试: 标题.spec.js import Vuetify from "vuetify"; import { shallowMount, createLocalVue } from "@vue/test-utils"; import router from "@/router"; import i18n from "@/locales"; import Heading from "@/components/Home/Heading.vue";
import Vuetify from "vuetify";
import { shallowMount, createLocalVue } from "@vue/test-utils";
import router from "@/router";
import i18n from "@/locales";
import Heading from "@/components/Home/Heading.vue";
describe("Heading.vue", () => {
let wrapper;
beforeEach(() => {
const localVue = createLocalVue()
localVue.use(router)
localVue.use(Vuetify)
localVue.filter("translate", function(value) {
if (!value) return "";
value = "lang.views.global." + value.toString();
return i18n.t(value);
});
wrapper = shallowMount(Heading, { localVue: localVue, router, i18n });
});
it("should contains default heading", () => {
console.log ('WRAPPER: ', wrapper)
// const heading = wrapper.find("h1");
// expect(heading.text()).toContain("In the heart of Charentes...");
});
});
当我运行它时,使用Vuetify获取错误

为什么检测到多个Vue实例?在我的测试中只定义了一次。。。就这些
考试通过了,但我不理解Vuetify的错误。。。。
感谢您的反馈通过不使用localVue解决了以下问题:
import Vue from "vue";
import { mount } from "@vue/test-utils";
import router from "@/router";
import Vuetify from "vuetify";
import i18n from "@/locales";
import Heading from "@/components/Home/Heading.vue";
describe("Heading.vue", () => {
let wrapper;
beforeEach(() => {
Vue.use(router);
Vue.use(Vuetify);
Vue.filter("translate", function(value) {
if (!value) return "";
value = "lang.views.global." + value.toString();
return i18n.t(value);
});
wrapper = mount(Heading, { router, i18n });
});
it('should have a happy ending', () => {
// You should see all Vuetify components properly rendered
// as normal HTML tags. For example, <v-flex> should be
// rendered as <div class="v-flex ...">
expect(wrapper.contains('div.flex')).toBe(true);
// Just so that you can visually inspect the rendered html.
console.log(wrapper.find('.subheading').html());
});
it("should contains default heading", () => {
const h1 = wrapper.find("h1");
expect(h1.is("h1")).toBe(true);
expect(h1.text()).toContain("In the heart of Charentes...");
});
});
从“Vue”导入Vue;
从“@vue/test-utils”导入{mount}”;
从“@/router”导入路由器;
从“Vuetify”导入Vuetify;
从“@/locales”导入i18n;
从“@/components/Home/Heading.vue”导入标题;
描述(“Heading.vue”,()=>{

Vue.use(路由器);
Vue.use(Vuetify);
Vue.过滤器(“翻译”,函数(值){

value=“lang.views.global.”+value.toString();

});
包装器=装载(标题,{router,i18n});
});
它('应该有一个幸福的结局',()=>{
//您应该看到所有Vuetify组件都已正确渲染

log(wrapper.find('.subheading').html());
});

常量h1=包装器。查找(“h1”);
期望(h1.is(“h1”)).toBe(true);
expect(h1.text()).toContain(“在Charentes的中心…”);

更新:以下是对的参考,由提供。有一种方法可以将localVue与vuetify插件的全局注册结合使用,如本期中所述:
从“Vue”导入Vue
从“Vuetify”导入Vuetify
从'@vue/test-utils'导入{mount,createLocalVue}
从“./my component.vue”导入组件
Vue.use(Vuetify)
const localVue=createLocalVue()
描述('模块',()=>{
让vuetify
在每个之前(()=>{
vuetify=新的vuetify()
})
它('应该做点什么',()=>{
常量包装=装载(组件{
localVue,
武装分子
})
})
})
对我来说,这解决了我在测试vuetify应用程序时遇到的问题。他们说使用localVue实例而不是污染全局Vue,但我知道,这很好。。。但是,由于测试中Vuetify中报告的错误:我无法使用LocalVue…@erwin哪个报告的错误?你有链接吗?我也对这个问题的链接很感兴趣。我在这里也面临着同样的问题,希望你的答案能够解决:)对于任何来到这里的人来说,问题是。这里是对官方Vuetify bug的引用:如果他们在自己的代码中没有修复bug,而是引用了Vuetify框架的设计,那么它对Vuetify框架的设计有什么影响?
