Constructor Function in Mocha not recognised

Question

I'm completely out of ideas as to what is going on here so hopefully someone can help.

Here is my script that I'm testing;

function MyFunc() {

    this.test = 'hello world';

};

module.exports = MyFunc;

Here is my test;

var expect = require('chai').expect;
var MyFunc = require('../myfunc.js');

describe('MyFunc', function() {

    it('test should equal to Hello World', function() {
        var subject = new MyFunc;
        expect(subject.test).to.eql('hello world');
    });

})

When I run the test it fails and it gives me this message;

TypeError: MyFunc is not a function

I've simplified the code just to get my problem across, but I've tried several variations to no avail. I've spent quite a bit of time looking for similar issues with no joy (usually that means it's something stupid I'm doing. Lets hope).

I test my Angular code in a very similar way with no issues at all. I'm stumped!

Thanks for taking the time to read,

Anthony

Change var subject = new MyFunc ===> var subject = new MyFunc()

 describe('MyFunc', function() { it('test should equal to Hello World', function() { var subject = new MyFunc(); expect(subject.test).to.eql('hello world'); }); })
