使用jest模拟vue的i18n

import { createLocalVue, mount } from '@vue/test-utils';
import VueI18n from 'vue-i18n';
import MyComponent from '@/components/MyComponent.vue';

describe('i18n', () => {
  test('should translate text correctly in English', () => {
    const localVue = createLocalVue();
    localVue.use(VueI18n);

    const i18n = new VueI18n({
      locale: 'en',
      messages: {
        en: {
          hello: 'Hello',
        },
      },
    });

    const wrapper = mount(MyComponent, {
      localVue,
      i18n,
    });

    expect(wrapper.text()).toContain('Hello');
  });

  test('should translate text correctly in French', () => {
    const localVue = createLocalVue();
    localVue.use(VueI18n);

    const i18n = new VueI18n({
      locale: 'fr',
      messages: {
        fr: {
          hello: 'Bonjour',
        },
      },
    });

    const wrapper = mount(MyComponent, {
      localVue,
      i18n,
    });

    expect(wrapper.text()).toContain('Bonjour');
  });
});
