我遇到了 Vue Test Utils 的问题。当我运行单元测试时，我总是会遇到：
TypeError{line: 73983, sourceURL: ' http://localhost:9876/base/index.js?045b00affe888fcd6b346c4fe50eadd13d471383 ', stack: 'mounted@ http://localhost:9876/base/index.js?045b00affe888fcd6b346c4fe50eadd13d471383:7:7 ......
这只发生在我在 Vue 组件中有mounted() 函数时
设置.vue
mounted() {
this.$refs.address.update(this.profile.address)
},
Settings.spec.js
it('calls updateUserInformation before mount', () => {
const spy = sinon.spy(Settings.methods, 'updateUserInformation')
shallow(Settings, { propsData })
Vue.nextTick().then(() => {
spy.should.have.calledOnce()
})
})
我正在使用Mocha & Chai和vue-test-utils。有谁知道为什么会这样？
先感谢您！
