Easmock partial mocking

Wow didnt knew I could partially mock a method on easy mock. Earlier i used to inherit the class and override methods to mock and have AtomicIntegers to determine which methods were called or not.  Recently I realized I was dumb and I should use easy mock to do that.

In below example I needed to very that if I get a json parsing exception for data stored in memcached then I need to delete the key from memcached. To test this I had to preserve all the code in MemCacheWrapper class but just mock the deleted method. here is how I did it.

    @Test
    public void testDeleteOldKeyOnJsonParse() throws Exception {
        String key="user.1";
        MemCacheWrapper sut = EasyMock.createMockBuilder(MemCacheWrapper.class).addMockedMethod("delete").createMock();       
        EasyMock.expect(sut.delete(key)).andReturn(true);
        EasyMock.replay(sut);
        sut.convertJsonToObject(key, User.class, "crap");
        EasyMock.verify(sut);
    }
