JSX: Unexpected token

hi!

I’m using example of ‘jest’ configuration from readme.md and this simple test

const renderer = require('react-test-renderer')

it('renders correctly', () => {
  const tree = renderer.create(<div>hi!</div>).toJSON()
  expect(tree).toMatchSnapshot()
})

gives the next Error:

   var tree = renderer.create(<div>hi!</div>).toJSON();
                                   ^
    SyntaxError: Unexpected token <

      at transformAndBuildScript (node_modules/jest-runtime/build/transform.js:285:10)
      at process._tickCallback (internal/process/next_tick.js:103:7)

Any ideas? I’d be grateful.

was there any resolution about this? I’m getting a similar error where I get a Syntax error while trying to use jsx within my tests 😭

That is used by the part of the preprocessor that takes care of displaying the correct line numbers in the typescript files. If you remove this, any failed tests you see will show you the line numbers in the compiled JS file.
