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。我想出了如何使用其ID查找元素的方法：

  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 
  });

但是我无法弄清楚如何访问输入的“值”。

任何帮助都将受到感激

Answer 1

我假设您的组件看起来像这样：

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

然后您可以尝试

   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');
  });
});

根据vue-test-utils documentation，您可以使用propsData或setProps将道具添加到组件中。

import { mount } from '@vue/test-utils'
import Foo from './Foo.vue'

const wrapper = mount(Foo, {
  propsData: {
    myProp: '223 Some Street Rd' // I am assuming the prop's value is '223 Some Street Rd'
  }
})
const street1 = wrapper.find('#street1') 
expect(street1.text()).toBe('223 Some Street Rd'); //.toEqual should also work

或者

import { mount } from '@vue/test-utils';
import Foo from './Foo.vue';

const wrapper = mount(Foo);
wrapper.setProps({ myProp: '223 Some Street Rd' }) // I am assuming the prop's value is '223 Some Street Rd'
const street1 = wrapper.find('#street1') 
expect(street1.text()).toBe('223 Some Street Rd'); //.toEqual should also work

使用Vue test-utils和jest测试特定输入元素的值
