Jasmine Spies are test doubles that can act as stubs, spies, fakes or when used in an expecation, mocks.
Spies should be created in test setup, before expectations. They can then be checked, using the standard Jasmine
expectation syntax. Spies can be checked if they were called or not and what the calling params were.
A Spy has the following mehtod: wasCalled, callCount, mostRecentCall, and argsForCall (see docs)
Spies are torn down at the end of every spec.
Note: Do < b > not< / b > call new jasmine.Spy() directly - a spy must be created using spyOn, jasmine.createSpy or jasmine.createSpyObj.
