我想测试bootstrap vue模式显示。在项目页面中,当点击按钮时,模式是通过toggleModal方法显示/隐藏。所以模态display
样式更改为none or ''
,反之亦然。在karma测试中,我想用所调用的方法测试该显示,但是它仅更改了数据而且样式属性没有改变,所以我在测试用例中失败了......
vm。$ nextTick(()=> {
期待(modal.style.display).toBe( '')
})
如何正确实现bootstrap-vue模态显示测试用例?
index.vue
<div id="example">
<button @click="toggleModal">Show</button>
<b-modal v-model="show" centered size="lg" title="確認">
<h1>Modal Test</h1>
<button @click="toggleModal">Hide</button>
</b-modal>
</div>
var vm = new Vue({
el: '#example',
data: {
show: false,
},
methods: {
toggleModal: function () {
this.show = !this.show
}
}
})
index.spec.js
import BootstrapVue from 'bootstrap-vue/dist/bootstrap-vue.esm'
import Vue from 'vue'
import Index from '~/components/index'
// Mock our router, store and nuxt-link
import Vuex from 'vuex'
// import NuxtLink from '~/.nuxt/components/nuxt-link'
import VueRouter from 'vue-router'
Vue.config.productionTip = false
Vue.use(BootstrapVue)
Vue.use(VueRouter)
Vue.use(Vuex)
describe('/components/index.vue', () => {
let vm
beforeEach(() => {
const Constructor = Vue.extend(Index)
vm = new Constructor().$mount()
})
it('check modal method', () => {
const modal = vm.$el.querySelector('.modal')
expect(modal.style.display).toBe('none')
modal.toggleModal()
vm.$nextTick(() => {
expect(modal.style.display).toBe('') //expect to pass , but fail
})
})
})

打开浏览器控制台,然后检查style.display
是否为Bootstrap-Vue模式,当hide()时值为无,值为阻止!重要当show()时。
所以将expect(modal.style.display).toBe('')
更改为expect(modal.style.display).toBe('block !important')
或
我不知道 Karma ,可能存在一种用法,例如expect(modal.style.display).toBe((item)=>{return item!=='none'})
答案 1 :(得分:0)
it('check modal method', () => {
const fm = new Vue(Index).$mount()
const modal = fm.$el.querySelector('.modal')
expect(modal.style.display).toBe('none')
modal.toggleModal()
fm.$nextTick(() => {
expect(modal.style.display).toBe('')
})
})
