Title Body

I have a simple test suite that has one it function inside of it. I want to see if a certain function is called within the function I'm calling, so I have something like this: describe("doStuff", function () { var foo = new Foo(); spyOn(foo, "doOtherStuff"); foo.doStuff(true); it("should do stuff and other stuff", function() { expect(foo.stuffDone).toBe(true); expect(foo.doOtherStuff).toHaveBeenCalled(); }); }); However, this gives me the error: Expected a spy, but got Function. After looking around some, I saw all examples had the spyOn in a beforeEach . So, I changed my test to: describe("doStuff", function () { var foo = new Foo(); beforeEach(function() { spyOn(foo, "doOtherStuff"); foo.doStuff(true); }); it("should do stuff and other stuff", function() { expect(foo.stuffDone).toBe(true); expect(foo.doOtherStuff).toHaveBeenCalled(); }); }); And this works. I'm pretty new to jasmine, so I may just be missing something obvious, but I just want to know why it has to be in a beforeEach for the spyOn to work. It's easy enough to just use the beforeEach , but I want to understand better what is going on. Thanks.
