SyntaxError: Unexpected token } in JSON at position 1097

Hi,

npm -v ;yarn -v; node -v 7.5.3 1.22.10 v15.9.0

vue-jest: 3.0.7

I am receiving the following error when testing the typescript class-based Vue component. It was working fine when I used the standard Vue component as soon as I migrated to typescript things started to fall apart. I have created a test repo, you can see it at https://github.com/asolopovas/vue-jest-test-repo, typescript tests are fine the error is thrown only when using Compoment.vue with lang="ts" attribute

Here is the error that I get:

 FAIL  specs/components/Products.spec.ts
  ● Test suite failed to run

    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".

    Here's what you can do:
     • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/en/ecmascript-modules for how to enable it.
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html
