How to generate Test for my Odata project

This is the method to try: (how to generate mock data for UriInfo)

public EntityCollection getEntitySet(UriInfo uriInfo) {

    logger.info("getEntitySet()");

    List<UriResource> resourcePaths = uriInfo.getUriResourceParts();
    UriResourceEntitySet uriResourceEntitySet = (UriResourceEntitySet) resourcePaths.get(0);
    EdmEntitySet edmEntitySet = uriResourceEntitySet.getEntitySet();
    EntityCollection entityCollection = getData(edmEntitySet);
    return entityCollection;
}

Right now I have this, but it fails in "(UriResourceEntitySet) resourcePaths.get (0) because it is null"

this is my code:

private DataViewController dataView = new DataViewController();

@Mock
private EntityProvider service = new GenericEntityProvider();
@Mock
private UriInfo uriInfo;

private MockMvc mockMvc;

@Before
public void setUp(){
    this.mockMvc = MockMvcBuilders.standaloneSetup(dataView).build();
}

/**
 * Get Entity test.
 */
@Test
public void getEntity() throws Exception {
    EntityCollection entityCollection = new EntityCollection();
    EntityProvider provider = new GenericEntityProvider();
    Mockito.when(provider.getEntitySet(uriInfo)).thenReturn(entityCollection);
    mockMvc.perform(get("http://localhost:8081/itaca/odata/PER_BANK")).andExpect(status().isNotFound());
}
