Below is my main component from which i am passing a function to children prop that will be accessible to its child modules:

import React from 'react';
import TestFunction from './testFunction';
const MainComponent = ({children, testId}) => {
const testFunc1 = (arg1) => {
const argObj = {};
argObj.arg1 = arg1;
argObj.testId = testId;
TestFunction(argObj);
}
return (
<div>{React.cloneElement(children, {testFunc: testFunc1})}</div>
)
}
MainComponent.propTypes = {
children: PropTypes.node.isRequired,
testId: PropTypes.string.isRequired,
}

This testFunc is accessed in different module which is not accessible. So on running npm run test, testFunc1 is not getting covered, I am not sure how to include this function in testing. We are using Jest to write test cases.
