  1. Very helpful, however there is a small bug in the RegExp that will cause .tsx files to be missed in the jest.config.ts file. The correct one is:

    transform: {
    ‘^.+\\.tsx?$’: ‘ts-jest’,
    },

      1. Additionally, that snipped has smart quotes rather than straight quotes, which will throw a syntax error in the file.
