How to test `functions.https.onCall` firebase cloud functions locally?

Question

I can't seem to find the solution for this in the Firebase Documentation.

I want to test my functions.https.onCall functions locally. Is it possible using the shell or somehow connect my client (firebase SDK enabled) to the local server?

I want to avoid having to deploy every time just to test a change to my onCall functions.

My code

Function :

exports.myFunction = functions.https.onCall((data, context) => {
  // Do something
});

Client:

const message = { message: 'Hello.' };

firebase.functions().httpsCallable('myFunction')(message)
  .then(result => {
    // Do something //
  })
  .catch(error => {
    // Error handler //
  });
