Unit testing 单元测试：如何在调用vuex中函数的输入上正确触发触发器事件？

我有这个引导vue组件：

  <b-form-input
    v-model="currentUser.name"
    placeholder="Name *"
    name="name"
    @input="checkSubmitStatus()"
  ></b-form-input>

这是.spec.js文件：

 import { createLocalVue, mount } from "@vue/test-utils";
 import Vue from "vue";
 import Vuex from 'vuex';
 import UserForm from "@/components/event-created/UserForm.vue";
 import { BootstrapVue, BootstrapVueIcons } from "bootstrap-vue";

 const localVue = createLocalVue();
 localVue.use(BootstrapVue);
 localVue.use(BootstrapVueIcons);
 localVue.use(Vuex);

 describe("UserForm.vue", () => {
   let mutations;
   let store;

   beforeEach(() => {
     mutations = {
       updateSubmitDisabled: jest.fn()
     };

     store = new Vuex.Store({
       state: {
         currentUser: {
           name: 'pippo',
         }
       },
       mutations
     });
   })

   it("should call the updateSubmitDisabled mutation", async () => {
     const wrapper = mount(UserForm, { localVue, store });

     const input = wrapper.get('input[name="name"]');

     await Vue.nextTick();
     input.element.value = 'Test';
     await input.trigger('input');
     await Vue.nextTick();

     expect(mutations.updateSubmitDisabled).toHaveBeenCalled();
   });
 });

目前，我只想测试是否在“name”上调用了“updateSubmitDisabled”，但测试结果显示： 预期呼叫数：>=1

收到的呼叫数：0

我最终与：

 it("should call the updateSubmitDisabled mutation", () => {
  const wrapper = mount(UserForm, { localVue, store });
  const input = wrapper.get('input[name="name"]');
  input.element.dispatchEvent(new Event('input'));
  expect(mutations.updateSubmitDisabled).toHaveBeenCalled();
 });

您可以在checkSubmitStatus中执行console.log以查看是否调用了它吗？

 it("should call the updateSubmitDisabled mutation", () => {
  const wrapper = mount(UserForm, { localVue, store });
  const input = wrapper.get('input[name="name"]');
  input.element.dispatchEvent(new Event('input'));
  expect(mutations.updateSubmitDisabled).toHaveBeenCalled();
 });
