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

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

SlingHttpRequest slingHttpRequest= mock(SlingHttpRequest);
slingHttpRequest.setAttribute("search", someObject);

When I try to print this attribute I get null. How do I set this property?

I'm probable 7 years late for the party, but I still would like to contribute.

You CAN set class property using the Whitebox from powermock:

Whitebox.setInternalState(mockedClass, "internalField", "Value to be returned")

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.

Mock object is not where you store data, it's for you to teach the behavior when its methods are invoked.

try this: https://www.google.com/search?q=mockito+example&oq=mockito+example&aqs=chrome..69i57j0l5.6790j0j7&sourceid=chrome&espv=210&es_sm=93&ie=UTF-8

You don't normally set properties on your mocked objects; instead, you do some specific thing when it's invoked.

when(slingHttpRequest.getAttribute("search")).thenReturn(someObject);
