Error with jest testing

[RiabininDmitriy]

When using screenfull version 6.0.1 , an error occurs when testing jest with enzyme ("enzyme": "3.11.0").Error text:

 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

    /home/dmitriy/clearslide-frontend/node_modules/screenfull/index.js:156
    export default screenfull;
    ^^^^^^

    SyntaxError: Unexpected token 'export'

the error is solved by switching to the version of screenfull 5.2.0

This is a problem with Jest, not this package.
