SyntaxError: Cannot use import statement outside a module in jest - vue.js

I would like to do vue util test using jest, but since i used import statement, it keeps making errors.
it says "SyntaxError: Cannot use import statement outside a module "
" at ScriptTransformer._transformAndBuildScript (node_modules/#jest/transform/build/ScriptTransformer.js:537:17)"
i've tried adding type:module to my package.json, transformIgnorePatterns to jest.config.js , and module to my script tag. none of them worked. i think it is related to version, as i am using vue 2 to get track of lessons im listening to. please take a look at my code
this is my package.json

this is my error code to test
<template>
<div>
{{ todo.title }}
</div>
</template>
<script>
import axios from "axios";
export default {
data() {
return {
todo: {},

async fetchTodo() {
const { data } = await axios.get(
"https://jsonplaceholder.typicode.com/todos/1"
);
this.todo = data;
},
},
};
</script>
and this is testing code
import { shallowMount } from "#vue/test-utils";
import TodoTitle from "#/components/TodoTitle";
describe("TodoTitle Component", () =\> {
test("rendering", () =\> {
const wrapper = shallowMount(TodoTitle);
console.log(wrapper);
expect(wrapper.text()).toBe("");
});
});

[Vue2 + module federation]: Error in dependencies "TypeError: Cannot read properties of undefined (reading 'warn')"

I'm trying to create a MicroFrontend in Vue2 using module federation, like Pinia provides a singleton behaviour about stores that could be awesome for use in module federation, the problem is when I inject this an error is prompt ( I make previous test in a unique application and that works )
That is the error:
And the piece of code relative is:
My configuration is the next:
Child1: Who exposed it's components contains this vue.config.js
const { defineConfig } = require('#vue/cli-service')
const {ModuleFederationPlugin} = require("webpack").container;
const deps = require("./package.json");
module.exports = defineConfig({
transpileDependencies: true,
publicPath: 'auto',
configureWebpack: {
plugins: [
new ModuleFederationPlugin({
name: 'child1',
filename: 'remoteEntry.js',
exposes: {
'./ResultsPage': './src/pages/ResultsPage',
'./Test1Page' : './src/pages/Test1Page',
'./Test2Page' : './src/pages/Test2Page',
'./appStore' : './src/store/appStore.js'
},
shared: require("./package.json").dependencies,
}),
],
}
})
And the package.json:

Parent: This is how works vue.config.js
const { defineConfig } = require("#vue/cli-service");
const { ModuleFederationPlugin } = require("webpack").container;
const ExternalTemplateRemotesPlugin = require("external-remotes-plugin");
const deps = require("./package.json");

}
In resume: I don't have a HTTP server because I'm making a build of the child and them using a HTTP server for support ( In the future I would like to add CDN to this children's )
All help would be accepted, really I'm in a stuck solution, so any movement to a solution would be great

I find this solution in answer
Works for me

Vue 3, Ionic 6 menu component shows black screen

Project was setup using Ionic's CLI, nothing custom, except some linter configs.
The problem: every time i try to use IonMenu, it just breaks the whole page.
Page Component:
<template>
<ion-page>
<ion-menu
side="start"
content-id="menuContent"
>
<ion-header>
<ion-toolbar color="secondary">
<ion-title>Menu</ion-title>
</ion-toolbar>
</ion-header>
<ion-content padding>
<ion-label>START MENU CONTENTS</ion-label>
</ion-content>
</ion-menu>
<ion-router-outlet id="menuContent" />
</ion-page>
</template>
<script>
import {
IonPage,
IonRouterOutlet,
IonContent,
IonHeader,
IonMenu,
IonTitle,
IonToolbar
} from '#ionic/vue';
import { defineComponent } from 'vue';
export default defineComponent({
name: 'index-page',
components: {
IonPage,
IonRouterOutlet,
IonContent,
IonHeader,
IonMenu,
IonTitle,
IonToolbar
}
});
</script>
Result (it's identical in browser and in emulator): nested menu content renders, but the page looks like this
If I remove <ion-menu> component, everything works just fine

I am getting error:
Test suite failed to run
Cannot find module 'vue-template-compiler' from 'vue-test-utils.js'
However, Jest was able to find:

You might want to include a file extension in your import, or update your 'moduleFileExtensions', which is currently ['js', 'jsx', 'json', 'vue', 'ts', 'tsx'].
See https://jestjs.io/docs/en/configuration#modulefileextensions-array-string
I checked similar questions such as Test suite failed to run Cannot find module 'vue-template-compiler when using jest in vue3 but it did not help me.
ah, I managed to find an answer in https://github.com/testing-library/vue-testing-library/issues/176
install this version of library #testing-library/vue#next such as
yarn add -D #testing-library/vue#next
or
npm i --save-dev #testing-library/vue#next
