babel issue when running jest in lerna reactjs repo

I've recreated the issue in this repo:

https://github.com/umarmw/lopital-sdk

whereby when executing lerna run test, it throws this error:

FAIL __tests__/doctor.test.js
  ● Test suite failed to run

    SyntaxError: /codebox/lopital-sdk/packages/doctor/__tests__/doctor.test.js: Support for the experimental syntax 'jsx' isn't currently enabled (9:24):

       7 | describe('doctor', () => {
       8 |     it('should be selectable by class "foo"', function() {
    >  9 |         expect(shallow(<Doctor title="MO" />).is('.btn-doctor')).toBe(true);
         |                        ^
      10 |       });
      11 | 
      12 |       it('should mount in a full DOM', function() {

    Add @babel/preset-react (https://git.io/JfeDR) to the 'presets' section of your Babel config to enable transformation.
    If you want to leave it as-is, add @babel/plugin-syntax-jsx (https://git.io/vb4yA) to the 'plugins' section to enable parsing.

I've added this @babel/preset-react in the babel preset, but it's not solving the issue.

Any idea?

I've fixed the above issue by adding babel.config.json inside each package folder as lerna will try to execute the code relative to each package.
