我目前正在使用Vue,基于类的组件,打字稿,pug,vuetify和Jest进行单元测试的项目中。我一直在尝试使用开玩笑来运行单元测试,但无法使其正常工作。在这一点上,我对可能出了什么问题很迷茫。看来使用vueifty时单元测试存在问题,我认为我已经解决了这个问题,但还不确定。当我运行测试时,测试失败,因为包装器始终为空。
<template lang="pug">
v-row(align="center" justify="center")
v-col(cols="6")
v-card
v-form(ref="loginForm" v-model="valid" v-on:keyup.enter.native="login")
v-card-title#title Login
v-card-text
v-text-field(class="mt-4" label="Username" required outlined v-model="username" :rules="[() => !!username || 'Username Required.']")
v-text-field(label="Password" required outlined password :type="show ? 'text' : 'password'" :append-icon="show ? 'visibility' : 'visibility_off'" @click:append="show = !show" v-model="password" :rules="[() => !!password || 'Password Required.']")
v-alert(v-if="error" v-model="error" type="error" dense dismissible class="mx-4")
| Error while logging in: {{ errorMsg }}
v-card-actions()
div(class="flex-grow-1")
v-btn(class="mr-4" color="teal" :disabled="!valid" large depressed @click="login") Login
div Forgot password?
a(href="/forgot-password" class="mx-2") Click here
div(class="my-2") Don't have an account?
a(href="/signup" class="mx-2") Signup
| for one
</template>
<script lang="ts">
import { AxiosError, AxiosResponse } from 'axios';
import JwtDecode from 'jwt-decode';
import { Component, Vue } from 'vue-property-decorator';
import { TokenDto, VForm } from '@/interfaces/GlobalTypes';
@Component({
name: 'LoginForm',
})
export default class Login extends Vue {
private password: string = '';
private username: string = '';
private show: boolean = false;
private error: boolean = false;
private errorMsg: string = '';
private valid: boolean = false;
... removed rest for brevity
import LoginForm from '@/components/auth/LoginForm.vue';
import login from '@/views/auth/LoginView.vue';
import { createLocalVue, mount } from '@vue/test-utils';
import Vue from 'vue';
import Vuetify from 'vuetify';
// jest.mock('axios')
Vue.use(Vuetify)
const localVue = createLocalVue();
console.log(localVue)
describe('LoginForm.vue', () => {
let vuetify: any
beforeEach(() => {
vuetify = new Vuetify()
});
it('should log in successfully', () => {
const wrapper = mount(LoginForm, {
localVue,
vuetify
})
console.log(wrapper.find('.v-btn'))
});
});
LoginForm已正确加载,但由于某种原因,它似乎认为该安装会创建包装器。当我登录包装器时,我得到:
VueWrapper {
isFunctionalComponent: undefined,
_emitted: [Object: null prototype] {},
_emittedByOrder: []
}
任何想法都非常有趣

您可以尝试:
wrapper.findComponent({name: 'v-btn'})

我想我迟到了,但我成功了。 我注意到您试图通过“v-btn”类查找 VBtn 组件,但 VBtn 并没有将其设为默认值。这就是为什么我决定用我自己的具有“v-btn”类的 VBtn 存根它。
import { shallowMount, Wrapper } from '@vue/test-utils'
import Login from '@/components/Login/Login.vue'
import Vue from 'vue'
import Vuetify from 'vuetify'
Vue.use(Vuetify)
let wrapper: Wrapper<Login & { [ key: string]: any }>
const VButtonStub = {
template: '<button class="v-btn"/>'
}
describe('LoginForm.vue', () => {
beforeEach(() => {
wrapper = shallowMount(Login, {
stubs: {
VBtn: VButtonStub
}
})
})
it('should log in successfully', () => {
console.log(wrapper.html())
})
})
测试通过后,您将在控制台日志中看到存根组件具有“v-btn”类。您可以添加自己的并随心所欲地使用它。
