Description

I want to spy and call through original function.

Issue

I am getting RangeError: Maximum call stack size exceeded

Environment

• node -v output: v14.19.1
• npm -v (or yarn --version) output: 6.14.16
• npm ls testdouble (or yarn list testdouble) version:

Failing Test

• Fork the repo
• Add a failing test (probably to the `/regression/src' directory)
• Submit a pull request for the failing test or link to your branch here

Example Repo

• Create a minimal repository that reproduces the issue
• Make sure that a fresh clone can run only npm it and observe the issue
• Link to that repo here

Runkit Notebook

• Create a Runkit notebook
• Invoke var td = require('testdouble') at the top
• Verify the behavior your issue is concerned with by clicking "Run"
• Link to the Runkit here

Code-fenced Examples

import * as td from 'testdouble';

const myObj = {
  myFunc(arg1, arg2) {
    console.log(`I am executed with: ${arg1} and ${arg2}`);
  }
};

// Create a test double for `myObj.myFunc`
const myFunc = td.replace(myObj, 'myFunc');

// Call through the test double and execute the original `myObj.myFunc` method
td.when(myFunc('foo', 'bar')).thenDo((...args) => myObj.myFunc(...args));

// Call the code that uses `myObj.myFunc`
myObj.myFunc('foo', 'bar');

// Verify that `myObj.myFunc` was called once with the specified arguments
td.verify(myObj.myFunc('foo', 'bar'), { times: 1 });

console.log('ALL TESTS PASSED!');

I would like to spy on an existing function and also execute it. Specifically, I want to run

console.log(`I am executed with: ${arg1} and ${arg2}`);

In some other libraries, this can be done with a callThrough method, but I have been unable to do so here. Instead, I am receiving a RangeError: Maximum call stack size exceeded.

How can I resolve this issue?
