mockito test error Invalid use of argument matchers

Question

I have been getting writing unit tests for a method that invokes jdbcTemplate.query and returns some data. It doesn't seems to be working and throwing exception.

Here's the code.

@Test public void NewDealDaoGetClientOwnershipValuesTest() { List<OptionView> optionViews = new ArrayList<OptionView>(); optionViews.add(new OptionView("one", "two")); when(jdbcTemplate.query("<some sql query>", newDealDaoImpl.getResultSetExtractor(Mockito.anyString(), Mockito.anyString(), Mockito.anyString()))).thenReturn(optionViews); assertEquals(newDealDaoImpl.getClientOwnershipValues(), optionViews); }

Error message

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

Just for your information that method newDealDaoImpl.getResultSetExtractor takes 3 arguments<String, String, String>.

The problem is that you are using argument matchers:

Mockito.anyString()

on an object that is not managed by Mockito (mock, spy etc.)

Try to pass an empty String or other random value to your:

newDealDaoImpl.getResultSetExtractor(...)

fixed code -

Mockito.when(jdbcTemplate.query(Mockito.anyString(), (ResultSetExtractor<Object>) Mockito.anyObject())).thenReturn(optionViews);

Try to use any(ResultSetExtractor.class). anyObject() should be the last resort. Cheers
