What is the difference between mock objects and stubs in Jasmine?
An example of an AI chatbot conversation about mock objects and stubs in Jasmine testing.
What is the difference between mock objects and stubs in Jasmine?
Mock objects and stubs are both used in testing, but they serve different purposes. Stubs provide predefined responses to method calls, while mocks are used to verify interactions between objects.
Can you give me an example of how to use a stub in Jasmine?
Sure! In Jasmine, you can create a stub using spyOn. For example, spyOn(obj, 'method').and.returnValue(value); will stub method to return value.
What about mock objects? How do they work in Jasmine?
Mock objects in Jasmine are created using spies as well. You can set expectations on them, like expect(obj.method).toHaveBeenCalled(); to verify that a method was called.
When should I use mocks instead of stubs?
Use mocks when you need to verify interactions and behavior, while stubs are best for providing controlled responses without verifying interactions.
