unit-testing - 使用 Vue test-utils 和 jest 测试特定输入元素的值

Question

使用 Vue test-utils，我需要测试通过 prop 填充的特定输入元素的值。我已经想出如何使用它的 id 找到元素:

  it("Address should render Street 1", () => {
     const street1 = wrapper.find('#street1')              // this works
     expect(street1).toEqual('223 Some Street Rd')         // nope
     expect(street1.text()).toEqual('223 Some Street Rd')  // seemed good at the time
     expect(street1.value()).toEqual('223 Some Street Rd') // grasping at straws - no love 
  });

但我一直无法弄清楚如何访问输入的“值”。

提前感谢任何帮助

我假设您的组件看起来像这样:

 <input id="street1" type="text" v-model="street1" >

那你可以试试

   expect(street1.element.value).toEqual('223 Some Street Rd');

例如

import { mount } from "@vue/test-utils";
import Input from "./Input";

describe("Input", () => {
  const mountInput = (propsData = {}) => {
    return mount(Input, {
      propsData
    });
  };

  it("Address should render Street 1", () => {
    const wrapper = mountInput();
    const street1 = wrapper.find('#street1') 
    expect(street1.element.value).toEqual('223 Some Street Rd');
  });
});
