Node.js unittest Stubbing Own function
Apologies if this was asked before. Here is the module that I'd like to unittest inside file getStuff.js. I'm having difficulty stubbing theresolveThing module used here.
getStuff.js
const resolveThing = require('./resolveThing.js');
module.exports = async function getStuff(target, stuff) {
const { element, test, other } = resolveThing(target);
try {
return element;
} catch (error) {
throw new Error('Did not work.');
}
};
And here is my attempt at the unittest with stubbing using sinon. However when I try to run this it errors out with TypeError: Cannot stub non-existent own property resolveType. Anyone know how I can get this test to work?
const getStuff = require('../com/getStuff');
const resolveThing = require('../com/resolveThing');
const mochaccino = require('mochaccino');
const { expect } = mochaccino;
const sinon = require('sinon');
describe('com.resolveThing', function() {
beforeEach(function () {
sinon.stub(resolveThing, 'resolveThing').returns({element:'a',test:'b',other:'c'});
});
afterEach(function () {
resolveThing.restore();
});
it('Standard message', function() {
const answer = getAttribute('a','b');
expect(answer).toEqual('a');
});
});

sinon.stub(resolveThing, 'resolveThing').returns({element:'a',test:'b',other:'c'});
resolveThing must be an object and 'resolveThing' must be a function in the object, an exception is thrown if the property is not already a function.
I think this is what's hapning in your case.

Yes, I suspect that is the case. Do you know how I can modify my test or function for it to work?

maybe you can create an object where you put your function like this: const resolveThingObject = {resolveThingFn : resolveThing}, and then use your new object: sinon.stub(resolveThingObject,'resolveThingFn').returns({element:'a',test:'b',other:'c'});
