无法识别Mocha中的构造函数

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'); }); })
