Proxyquire not stubbing

I'm trying to get Proxyquire to work with a simple method substitution but I can't figure out what I'm doing wrong.

I create lib.js

module.exports = {
    thing: () => {
        console.log("thing");
    }
};

And test.js

const lib = require("./lib");

module.exports = () => {
    lib.thing();
};

And the and attempted to stub the dependency and replace thing with another function ie 

const proxyquire = require("proxyquire");
const libStub = {};
const test = proxyquire("./test", {"lib": libStub});

test();

libStub.thing = () => {
    console.log("replaced");
};

test();

But test is logging out "thing" both times instead of "replaced" on the second call. Any help is appreciated.

The best way to solve this issue, as long you will face it many times in the future is to use:

Both will throw an exception in case they fail to mock something with extract reason and extract file names they tried to use.

in proxyquire, use the same path that you use in the require itself :

so should be :

const proxyquire = require("proxyquire");
const libStub = {
  thing: () => console.log('replaced')
};
const test = proxyquire("./test", {"./lib": libStub});
test();
