Override spy return value in nested describe

[Steve Horn]

I have a beforeEach in a describe that creates a spy via:
var someSpy = jasmine.createSpy('SomeObject');.

Then I set up a stub for a method on that object:
someSpy.some_method =
jasmine.createSpy("some_method").andReturns("FOO");

That works fine and all, but the rub comes in when I want to reference
the same spyed-upon object in a describe context nested within the
describe I mentioned above.

Instead of returning "FOO" in my nested describe, I want it to return
"BAR". I tried simply re-declaring the spy, but I get a error from
Jasmine:
"Error: some_method has already been spied upon "

Is there any way for me to redefine the return value for a spy in a
nested describe?

Can you reset the spy and set it up again?

Apologies if there's syntax goofs -- it's been awhile: 

var spy = jasmine.createSpy("spyname").andReturn("foo")

someObj.method = spy;

expect(someObj.method()).toEqual("foo");

spy.andReturn("bar");

expect(someObj.method()).toEqual("bar");

You could also, as Corey suggests, reset the spy, but keep in mind that will reset callCounts, etc (this may be what you want). 

If you're spying on a defined object, consider: 

spyOn(someObj, "method").andReturn("foo");

expect(someObj.method()).toEqual("foo");

someObj.method.andReturn("bar");

expect(someObj.method()).toEqual("bar");

Thanks!

Thanks for the tip, "resetting" the spy worked.

Insetad of recreating the spy:
spyOn(object, 'methodName').andReturn("foo");

In the nested describe change the return value on the existing spy:
object.methodName.andReturn("bar");

Not as fluent (since you lose the "spyOn" method call), but it works.

This no longer works for Jasmine 2.5. Is there an alternative?

Based on this email, I can't tell what functionality you're looking for. A couple of things though:

1. If you're spying on a method on an object, you should probably use `spyOn` as it will be cleaned up after each spec. `createSpy` is intended for other use cases.

2. If you want to change the behavior of the spy, you can call `.and.<whichever>` again at a later date on the same spy object.

If you want more details, take a look at the docs as well: https://jasmine.github.io

Hope this helps. Thanks for using Jasmine!
