Mockito not allowing Matchers.any() with Integer.class

Question

I am trying to unit test this method:

/**
     * finds all widget descriptions containing specified text
     * @param searchText
     * @return
     */
    @Transactional
    public List<Integer> returnWidgetIdsFromSearchWord(String searchText){
        List<Integer> widgetIds = new ArrayList<Integer>();
        MapSqlParameterSource args = new MapSqlParameterSource();

        try{
            widgetIds = (List<Integer>) jdbt.queryForList("SELECT idwidgets FROM descriptions "
                    + "WHERE descriptiontext LIKE '%"+ searchText + "%'", args, Integer.class);
        }catch(Exception e){

        }

        return widgetIds;
    }

with this JUnit test:

@Test
    public void testReturnWidgetIdsFromSearchWord(){
        List<Integer> widgetIds = null;

        when(jdbt.queryForList(Matchers.anyString(), 
                Matchers.any(MapSqlParameterSource.class),
                 Matchers.any(Integer.class))).thenReturn(idList);

        widgetIds = (List<Integer>) dDao.returnWidgetIdsFromSearchWord("someText");

        assertEquals(widgetIds, idList);
    }

I have tried just use Integer.class without the Matcher - no luck because then it complains about needing 3 matchers. Any suggestions? And thanks

Answer 1

Do not cast Matchers.anyVararg(), there is better solution.

Method queryForList has signature

queryForList(String sql, SqlParameterSource paramSource, Class<T> elementType)

so instead of

when(jdbt.queryForList(Matchers.anyString(), 
                       Matchers.any(MapSqlParameterSource.class),
                       Matchers.any(Integer.class))).thenReturn(idList); 

use

when(jdbt.queryForList(Matchers.anyString(), 
                       Matchers.any(MapSqlParameterSource.class), 
                       Matchers.<Class<Integer>>any())).thenReturn(idList);

as described in Mockito: Verifying with generic parameters

Do not use code with anyVararg() and casting

when(jdbt.queryForList(Matchers.anyString(), 
                       Matchers.any(MapSqlParameterSource.class), 
                       (Class<Object>) Matchers.anyVararg()).thenReturn(idList);

because this generate warning

Unchecked cast: `java.lang.Object` to `java.lang.Class<java.lang.Object>`
