Invalid use of argument matchers

Question

The simple test case below is failing with an exception.

org.mockito.exceptions.misusing.InvalidUseOfMatchersException: Invalid use of argument matchers! 3 matchers expected, 2 recorded: 

I am not sure what is wrong

@Test public void testGetStringTest(){      final long testId = 1;     String dlrBAC = null;     NamedParameterJdbcTemplate jdbcTemplate = mock(NamedParameterJdbcTemplate.class);     when(this.dao.getNamedParameterJdbcTemplate()).thenReturn(jdbcTemplate);     when(jdbcTemplate.queryForObject(anyString(), any(SqlParameterSource.class), String.class                         )).thenReturn("Test");     dlrBAC =  dao.getStringTest(testId);     assertNotNull(dlrBAC);  } 

Answer 1

Mockito requires you to either use only raw values or only matchers when stubbing a method call. The full exception (not posted by you here) surely explains everything.

Simple change the line:

when(jdbcTemplate.queryForObject(anyString(), any(SqlParameterSource.class), String.class                         )).thenReturn("Test"); 

to

when(jdbcTemplate.queryForObject(anyString(), any(SqlParameterSource.class), eq(String.class)                         )).thenReturn("Test"); 

and it should work.
