Testing vue component that rendered many child component with v-for directive

this is my component called Musics.vue:

<template>
  <div class="flex flex-wrap mb-20 md:mb-32">
    <div
      v-for="(music, index) in musics"
      :key="index"
      class="w-full sm:w-6/12 lg:w-3/12 p-3"
    >
      <MusicCard :music="music" @play="setCurrent($event)" />
    </div>
  </div>
</template>

as you see MusicCard is in the loop. and each MusicCard emit play event to parent component. have can i write test for it? (i tried to use forEach but it failed)

this is my test:

  it("commits a mutation when 'MusicCard' component emits play event", () => {
    const components = wrapper.findAllComponents({ name: "MusicCard" });
    expect(components.exists()).toBe(true);
    
  });

thanks for your helping.
