Mocking a global function

[Blake VandeMerwe]

How do I mock (spy) a function in the global space?

For example, I have in common.js:

isPending() { ... }

...and I need this mocked to return True when a second function is
being tested. How is this done since it doesn't follow the prototype
convention? This is being tested with jasmine, jasmine adapter, and
jstestdriver.

Thanks in advance.

you need a reference to the global object. if you're doing in-browser testing, it's "window"

spyOn(windows, "globalFunction");

otherwise, a simple function to retrieve it can be useful:

var global = (function(){ return this; })();

spyOn(global, "globalFunction");

Note that Jasmine also has a function that will give you the global object. 

jasmine.getGlobal()

spyOn(window, 'isPending');

Should do the trick.
