Nuxt3 can't import component in tests - vuejs3

Question

I'm trying to run a component unit test on Nuxt 3 but I get an error telling me that the component cannot be found..
FAIL test/components/button.test.ts [ test/components/button.test.ts ]
Error: Failed to resolve import "#/components/Texts/Button/ButtonText.vue" from "components\Button\Button.vue". Does the file exist?
button.spec.ts
import {test, expect} from 'vitest';
import {mount} from '#vue/test-utils';
import Button from "../../components/Button/Button.vue";
test('Button Component', async () => {
const button = mount(Button, {
props: {
text: 'My Test Button'
}
});
expect(button.text()).toEqual('My Test Button');
});
Button.vue
<template>
<div class="Button">
<slot name="left" />
<ButtonText :text="text" />
<slot name="right" />
</div>
</template>
<script lang="ts">
export default {
name: 'Button',
components: {ButtonText},
props: {
// Text to display in the button
text: {
type: String as () => string,
default: 'Button',
required: true,
},
}
}
</script>
any ideas ?

Assuming, that #/components/Texts/Button/ButtonText.vue actually exists, a solution to your problem might be adding aliases to your ./vitest.config.ts like that:
// vitest.config.ts
import { defineConfig } from 'vite'
import { aliases } from './aliases'
export default defineConfig({
resolve: { aliases },
// ... further settings
})
// aliases.ts
import { resolve } from 'path';
const r = (p: string) => resolve(__dirname, p);
export const alias: Record<string, string> = {
'~~': r('.'),
'~~/': r('./'),
'##': r('.'),
'##/': r('./'),
// ... other aliases
};
