How do I set a property on a mocked object using Mockito?

Question

I have a scenario where I have to set a property of a mocked object as follows:

SlingHttpRequest slingHttpRequest= mock(SlingHttpRequest);
slingHttpRequest.s         


        

Answer 1

I'm afraid you're misusing your mock SlingHttpRequest.

Mockito requires you to wire up your mock's properties before you use them in your test scenarios, i.e.:

Mockito.when(slingHttpRequest.getAttribute("search")).thenReturn(new Attribute());

You cannot call the setAttribute(final Attribute a) method during the test like so:

slingHttpRequest.setAttribute(someObject);

If you do this, when the test runs, getAttribute() will return null.

Incidently, if the code you are unit testing is going to call a setter on your mock in this way, do not use a mock. Use a stub.
