Answer №1

After extensive research and debugging, I was able to successfully resolve the issue on my own. I found helpful information on this blog post:

1. Addition of babel.config.js

module.exports = {
    env: {
        test: {
            presets: [
                ['@vue/cli-plugin-babel/preset'],
                [
                    '@babel/preset-env',
                    {
                        targets: {
                            node: 'current',
                        },
                    },
                ],
            ],
        },
    },
};

2. Modification of "exclude" value in tsconfig.json (with only an order difference)

 "exclude": [
        "*.config.js","node_modules", ".nuxt", "dist"]
    }

3. Downgrade to TypeScript version "3.8.3" and babel-jest version "^26.0.0" as suggested by error messages.
