Bug: wrapper.findComponent no longer working after upgrading to 2.4.2

[SimonHawesome]

Describe the bug

Ever since we updated to v2.4.2, we've been experiencing an error with wrapper.find and wrapper.findComponent.

Error: Cannot call vm on an empty VueWrapper.

The find and findComponent methods no longer return a VueWrapper.

To Reproduce

// .vue file
<component data-attribute-handle @close="handleClose"></component>

// test file
wrapper.findComponent('[data-attribute-handle]').vm.$emit('close')

Expected behavior

We are expecting the component to be returned so we can call methods on the component's vm.

wrapper.findComponent('[data-attribute-handle]').vm.$emit('close')
or
wrapper.findComponent('[data-attribute-handle]').vm.selected

Hi @SimonHawesome

Have you tried with the latest version of Vue (v3.4.15) and VTU (v2.4.4) as well?

If it doesn't work, can you provide us a small repro online using https://stackblitz.com/github/vuejs/create-vue-templates/tree/main/typescript-vitest?file=src%2Fcomponents%2F__tests__%2FHelloWorld.spec.ts ?

It only takes a few minutes, and we'll be able to take a look

Hi @SimonHawesome

Did you manage to build a repro or did you fix your issue and we can close this?

[SimonHawesome]

Sorry haven't be able yet, perhaps this week!

Hi are you using vitest? If so you may need to add

    server: {
      deps: {
        inline: ['@vue/test-utils'],
      },
    },

to your vitest config.

Hi @SimonHawesome

Let me know if you have a repro or if we can close the issue (we can't look into it otherwise). I suspect that using both the later versions of VTU and Vue should be enough to solve it, but I'll wait for your answer before closing.

Let's close the issue as we had no repro from the OP author.
