Experimenting with JavaScript within an Immediately Invoked Function Expression

My team leader is requesting that I encapsulate my JavaScript code within an Immediately-Invoked Function Expression (IIFE). However, I am struggling to use spyOn in my Jasmine spec file.

How can I properly use spyOn on the following:

(function(){
    function_1(){...}
    function_2(){...}
});

The method spyOn(window,'function_1') is not working. Even passing window into the IIFE is unsuccessful.

Attempting both (x=function()... and (function x() ..., followed by spyOn(x,'function_1'), also fails to work.

I have been unable to locate any relevant information online regarding this issue.
