在这个测试中,我只是试图断言该end
属性是在被测组件上设置的(DateRangeEditor
)。该组件假定this.$refs.datepicker
是一个实例HotelDatepicker
并调用它的setCheckOut
和setCheckIn
方法(如果有更好的方法可以做到这一点,请告诉我!)。
该组件在浏览器中正常加载时工作,但我的测试setEndDate
失败并出现“TypeError:this.$refs.datepicker.setCheckIn is not a function”。
我是否误解了该stubs
选项应该做什么设置?我认为像这样的场景,调用代码只需要调用存根函数而不需要特定的结果,正是存根的用途。我只是用错了吗?
这是我的测试:
import { mount, shallow } from 'vue-test-utils'
import DateRangeEditor from '../../assets/src/components/DateRangeEditor.vue'
describe('DateRangeEditor', () => {
describe('@checkOutChanged', () => {
it('sets a new end date', () => {
const wrapper = shallow(DateRangeEditor, {
stubs: ['datepicker']
})
// simulate user changing the end date
const date = new Date(2017, 11, 1)
wrapper.vm.$refs.datepicker.$emit('checkOutChanged', date)
expect(wrapper.vm.end).to.equal(date)
})
})
describe('@checkInChanged', () => {
it('sets a new start date', () => {
const wrapper = shallow(DateRangeEditor, {
stubs: ['datepicker']
})
// simulate user changing the start date
const date = new Date(2017, 11, 1)
wrapper.vm.$refs.datepicker.$emit('checkInChanged', date)
expect(wrapper.vm.start).to.equal(date)
})
})
})
这是我的(非常简化的)DateRangeEditor
组件:
<template>
<div class="date-range-editor-container">
<datepicker
@checkInChanged="setStartDate"
@checkOutChanged="setEndDate"
ref="datepicker"
></datepicker>
<button type="button" @click="save" class="btn save-btn">Save</button>
<button type="button" @click="cancel" class="btn cancel-btn">Cancel</button>
</div>
</template>
<script>
import HotelDatePicker from 'vue-hotel-datepicker'
export default {
methods: {
setStartDate: function(newDate) {
if (newDate) {
// make sure newDate has an hour component
newDate.setHours((new Date()).getHours())
this.$refs.datepicker.setCheckIn(newDate)
this.start = newDate
}
},
setEndDate: function(newDate) {
if (newDate) {
// make sure newDate has an hour component
newDate.setHours((new Date()).getHours())
this.$refs.datepicker.setCheckOut(newDate)
this.end = newDate
}
},
save: function() {
this.$emit('save', this.$data)
},
cancel: function() {
this.$emit('cancel', this.$data)
},
},
data: function() {
return {
start: '',
end: '',
}
},
components: {
datepicker: HotelDatePicker,
}
}
</script>
<style>
</style>
最后,这是我的 setup.js 引导文件:
/* globals global */
require('jsdom-global')()
const chai = require('chai')
const sinon = require('sinon')
// use Sinon test spies/stubs/mocks in all tests
chai.use(require('chai-sinon'))
// expose libs to all tests
global.chai = chai
global.sinon = sinon
global.expect = chai.expect
