我如何模拟这个Vue注入？

// MyComponent.vue
<template>
  <div>{{ message }}</div>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello, Vue!'
    }
  }
}
</script>

// MyComponent.spec.js
import { shallowMount } from '@vue/test-utils'
import MyComponent from '@/components/MyComponent.vue'

describe('MyComponent', () => {
  it('renders the message', () => {
    const wrapper = shallowMount(MyComponent, {
      mocks: {
        $t: () => 'Translated Text',
        $i18n: {
          locale: 'en'
        }
      }
    })

    expect(wrapper.text()).toBe('Hello, Vue!')
  })
})
