Vue js Jest异步测试

Question

我遇到了问题。当我挂载组件Jest而不是等待解决promises.fetch API不在生命周期挂载中执行时。我尝试了flushPromises但无法正常工作。我也尝试过mocha但存在相同的问题。

   describe('HelloWorld.vue', () => {
  it('should render correct contents', async () => {
    try {
      const wrapper = mount(HelloWorld, {
        store,
        localVue,

      })    

      await wrapper.vm.$nextTick()      
     await  flushPromise()

       expect(wrapper.contains('.hellonew')).toEqual(true)

    } catch (error) {
      console.log(error)
    }
  })
  afterEach(() => {
    fetchMock.restore()
  })
})

我的组件包含生命周期，可以从API获取数据并将其存储

    import { mapGetters, mapActions } from "vuex";
export default {
  name: "HelloWorld",
  data() {
    return {
      msg: "Welcome to Your Vue.js App",
      loading: false
    };
  },
  methods: {
    ...mapActions(["setData"])
  },
  mounted() {

    this.setData();
  },
  computed:{
    ...mapGetters(['getData']),
    gg(){
      if(this.getData){
          console.log('99999')
      }
    }
  }
};
