问题 I am using react-ga v2.5.7, for which I updated react-redux v7.0.2, and I am using jest v24.7.1 I set react-ga in testMode , and it is mocked in my jest.setup.js . But everytime I run my tests I am always encountering the same issue, most of the tests are failing for some weird reason: Test suite failed to run Cannot find module '@icons/material/CheckIcon' from 'SwatchesColor.js' However, Jest was able to find: './SwatchesColor.js' You might want to include a file extension in your import, or
