How can I use Jasmine for spying in my tests?
You can use Jasmine's spyOn
function to create spies on methods of objects. This allows you to track calls and arguments.
Can you give me an example of how to spy on a method?
Sure! If you have an object obj
with a method methodName
, you can do this: spyOn(obj, 'methodName');
.
What can I do with the spy after creating it?
You can check if the method was called using expect(obj.methodName).toHaveBeenCalled();
or get the arguments it was called with.
Can I also use spies with asynchronous methods?
Yes, you can! Just make sure to handle the asynchronous behavior properly using Jasmine's done callback.
