Note, you don't need to always import t in components for tests, it is not required. We can setup component's globals in the mount function, including installing plugins: See:

• mountOptions.global.plugins to install plugins: https://test-utils.vuejs.org/api/#global
• config.global to make it globally: https://test-utils.vuejs.org/api/#config-global

Can you describe the fix(vue3): fix double emitting commit?

As was discussed in the office: Vue2 and Vue3 behave differently at this moment:

• in Vue 2 component is destroyed before bubbling event is triggered
• in Vue 3 event bubbles, (and fires twice), then got destroyed
