NullPointerException when verify called on method using "when" with any() method #102

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I know this isn't the greatest usage but I'd like the method to return the
same value for any call then verify the correct call was made. 

I do need to verify the parameters but in my case, I'd like the failure to
be obvious (at the validate line) and not implicit (checking for the
correct return value).

I've tried this against 1.8-rc2:
 <dependency>
  <groupId>org.mockito</groupId> 
  <artifactId>mockito-all</artifactId> 
  <version>1.8.0-rc2</version> 
  </dependency>

------------------------------------
-- Example interface (to be mocked):
------------------------------------
public interface Fun {

    public String doFun(String something);

}

------------------------------------
-- Example test: 
------------------------------------

        @Mock private Fun mockFun;
    @Test
    public void testMockitoTest()
    {
        //setup
        when(mockFun.doFun((String)any())).thenReturn("value");

        //do
          mockFun.doFun(null);

        //verify
        verify(mockFun).doFun("hello");

    }
