Installing jest & vue test utils manually no - trouble with import - vue.js

I am trying to install vue-test-utils and jest in a project. It is vue-cli project but I did not setup the testing when I ran it initially.
It finds the test but fails on the import statements.
Here is the error.
Jest encountered an unexpected token
This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.
By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".
It is almost certainly a babel thing (I think) but I cannot work it out.
Here are the config files.
babel.config.js
module.exports = {
presets: [
'#vue/app'
]
}
jest.config.js
module.exports = {
moduleFileExtensions: [
'js',
'jsx',
'json',
'vue'
],
transform: {
'^.+\\.vue$': 'vue-jest',
'.+\\.(css|styl|less|sass|scss|svg|png|jpg|ttf|woff|woff2)$': 'jest-transform-stub',
'^.+\\.jsx?$': 'babel-jest',
"^.+\\.js$": "<rootDir>/node_modules/babel-jest"
},
transformIgnorePatterns: [
'/node_modules/'
],
moduleNameMapper: {
'^#/(.*)$': '<rootDir>/src/$1'
},

Well, looks like you need global section in your jest config. I'm using vue + ts, so my globals looks like that:
globals: {
'ts-jest': {
babelConfig: true
}
}

IE11 Error: SCRIPT1006 - Expected ')' with vue app

I am having difficulties telling vue to polyfill my application in a way that it runs on IE11.
If I understand everything correctly, I have to tell my npm build to insert core-js and regenerator-runtime for my generator functions.
The app works fine on Chrome/Firefox, but I persistently get the error SCRIPT1006: Expected ')' on IE11.
Can someone point me in a direction to solve this?

When I look online for a solution every page says Vue should read the config file. But it does not, since I tried console logging there and it had no output. Anyone knows more about this?

How to configure jest and babel to work with vue?

I'm adding jest to my project and can't configure it properly.
When I run $ jest I'm getting a SyntaxError: Cannot use import statement outside a module.
I've searched for quite a while for a solution but none worked...
Can someone please help me config jest and babel?

npm run build generates more files than just bundle.js bundle.css

I'm working on a SPA with Vue.js and Django.
I run npm run build to generate the bundle files that will be used in production. I was expecting to only generate two files: dist/bundle.js and dist/bundle.css. However, besides the aforemetnioned files, a third js file is also being generated: dist/js/about.add8abe8.js.
Why is this?
In my Django project, inside the frontend/src/views/ directory I have 3 Vue components: Home.vue, List.vue and About.vue.
EDIT:
I don't have a webpack.config file. But these are some other files that may be relevant:
