Please can you help me to get my jest tests to run. My create-react-app (es6) with redux builds and runs in the browser as expected.
I think there is something wrong with my imports in jest, but not sure what.
Can you please help me to understand why my jest test is failing?
FAIL src/components/__tests__/CommentBox.test.js
● Test suite failed to run
Cannot find module 'react' from 'Provider.js'
However, Jest was able to find:
'components/Provider.js'
You might want to include a file extension in your import, or update your 'moduleFileExtensions', which is currently ['web.js', 'js', 'web.ts', 'ts', 'web.tsx', 'tsx', 'json', 'web.jsx', 'jsx', 'node'].
