如何模拟计算方法以停止测试中的json方法错误(Vue- test -utils和vuetify)

import { createLocalVue, shallowMount } from '@vue/test-utils';
import Vuetify from 'vuetify';

const localVue = createLocalVue();
localVue.use(Vuetify);

const MyComponent = {
  template: '<div>{{ computedValue }}</div>',
  computed: {
    computedValue() {
      // 在这里编写计算属性的逻辑
      return 'computed value';
    }
  }
};

const wrapper = shallowMount(MyComponent, { localVue });

wrapper.vm.computedValue = 'mocked value';

expect(wrapper.text()).toBe('mocked value');
