vue test utils mount option data not working with compostion api

Question

When i am learning the vue-test-utils from the offical site conditional-rendering.

I tried to change the option api to composition api. It seems like the mount option data not working with the composition api.

Nav.vue Composition API test FAIL

<template>
  <div>
    <a id="profile" href="/profile">My Profile</a>
    <a v-if="admin" id="admin" href="/admin">Admin</a>
  </div>
</template>

<script setup lang="ts">
import { ref } from 'vue'

const admin = ref(false)
</script>

Nav.vue Option API test PASS

<template>
  <div>
    <a id="profile" href="/profile">My Profile</a>
    <a v-if="admin" id="admin" href="/admin">Admin</a>
  </div>
</template>

<script>
export default {
  data() {
    return {
      admin: false,
    }
  },
}
</script>

Nav.spec.js test

test('renders an admin link', () => {
  const wrapper = mount(Nav, {
    data() {
      return {
        admin: true
      }
    }
  })

  // Again, by using `get()` we are implicitly asserting that
  // the element exists.
  expect(wrapper.get('#admin').text()).toEqual('Admin')
})

I found a solution but I don't know if it's a good solution

test("renders an admin link", async () => {
   const wrapper = mount(Nav);
   wrapper.vm.admin = true;
   await nextTick();

   expect(wrapper.get("#admin").text()).toEqual("Admin");
});
