Import error when running Jest tests that use the PouchDB Asyncstorage adapter

Question

I'm getting this error when running tests in Jest. I've tried mocking pouchdb-adapter-asyncstorage and the polyfill both in the module, automock, and globally.

Without modifying pouchdb-adapter-asyncstorage library, how can I squash this issue?

Update: Based on my research, it seems that this library hasn't been fully updated to an ES6 module and babel might be able transform it.

pouchdb-adapter-asyncstorage source code

  ● Test suite failed to run

node_modules/pouchdb-adapter-asyncstorage/src/index.js:3
    import './polyfill'
           ^^^^^^^^^^^^

    SyntaxError: Unexpected string
