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?
Here are my files:

I need to add UglifyJS to a VueJS CLI 3 project.
My vue.config.js:
var webpack = require('webpack')
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
module.exports = {
// ...
optimization: {
minimizer: [new UglifyJsPlugin()],
},
publicPath: "./",
plugins: [
// ...
new webpack.DefinePlugin({
'process.env.NODE_ENV': JSON.stringify('production')
})
]
}
This is the error message I get after trying to run npm run build.
Invalid options in vue.config.js: "optimization" is not allowed.
"plugins" is not allowed
I tried updating all packages and install the webpack UglifyJS plugin.

How to add UglifyJS to the VueJS project?
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'
},
snapshotSerializers: [
'jest-serializer-vue'
],
testMatch: [
'**/tests/unit/**/*.spec.(js|jsx|ts|tsx)|**/__tests__/*.(js|jsx|ts|tsx)'
],
testURL: 'http://localhost/'
}

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
}
}
