Mockito problem testing for a boolean value

[Tony Evans]

I have a object a controller in which I set cachecontrol headers

if(cacheControl){
        	HttpServletResponse resp = (HttpServletResponse) response;   
        	resp.setHeader("Cache-Control",  "max-age=0,must-revalidate");             
        	resp.setHeader("Last-Modified", new Date(inputFile.lastModified()).toString());                        
        }

In my test for testing this controller I pass in a mockResponse object.

I am trying to find ways to test that the headers have been set. In real life this would be

Boolean bool = response.containsHeader("Cache-Control");

But in a mock response object this call would always default to false.

I thought this might work, but I dont think its correct for handling an checking boolean returns.

Mockito.verify(mockResponse).containsHeader("Cache-Control");

Thanks for any help Tony

I think how mockito works in this case, is it checks was the method called with these parameters in this case

 Mockito.verify(mockResponse).setHeader("Cache-Control",  "max-age=0,must-revalidate");

which works.

Now I come to my second problem.

Mockito.verify(mockResponse).setHeader("Last-Modified", date.toString());

will return

Argument(s) are different! Wanted:
mockResponse.setHeader(
"Last-Modified",
"Wed Sep 21 16:09:42 BST 2011"
);

Which is true as the string date representaion is different to the data the file was last modified.

I tried

Mockito.verify(mockResponse).setHeader("Last-Modified", Matchers.anyString());

This returns

org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
Invalid use of argument matchers!
2 matchers expected, 1 recorded.
This exception may occur if matchers are combined with raw values:
//incorrect:
someMethod(anyObject(), "raw String");
When using matchers, all arguments have to be provided by matchers.
For example:
//correct:
someMethod(anyObject(), eq("String by matcher"));
