spring boot - web mvc test does not find controller mapping - spring

Question

In this spring-boot project the following WebMvcTest fails because the GET /items mapping from the ItemController is not found
#RunWith(SpringRunner.class)
#WebMvcTest(ItemController.class)
#AutoConfigureMockMvc
public class Test_ItemController {
#Autowired
private MockMvc mvc;
#MockBean
private ItemDao dao;
#MockBean
private CartDao cartDao;
#Test
public void test() throws Exception {
// setting up mock response
Cart cart = new Cart();
cart.setId(1);
Item item = new Item();
item.setCart(cart);
item.setItemName("toothbrush");
item.setId(1);
//---------------------
List<Item> items = new ArrayList<>();
items.add(item);
given(this.dao.findAll()).willReturn(items);
this.mvc.perform(get("items").accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk());
}
}
The error is:
2018-02-26 12:10:45.816 WARN 12252 --- [ main] o.s.web.servlet.PageNotFound :
No mapping found for HTTP request with URI [items] in DispatcherServlet with name ''

Here is the controller (just a little experiment, so don't focus on missing ResponseEntity and missing service layer)
#RestController
public class ItemController
{
private static final Logger LOG = LoggerFactory.getLogger(ItemController.class);
#Autowired ItemDao dao;
#GetMapping("items")
public List<Item> getAll()
{
List<Item> res = new ArrayList<>();
dao.findAll().forEach(res::add);
return res;
}
#PostMapping("items")
public Item addItem(#RequestBody Item item)
{
return dao.save(item);
}
#GetMapping("items/{item_id}")
public Item getItemById(#PathVariable("item_id") long item_id)
{
Item item = dao.findById(item_id).get();
LOG.info(" ---------------- Retrieved item: {}", item.toString());
return item;
}
}

Thanks for the help

Answer 1

Yes, ok I forgot the slash in the endpoint
this.mvc.perform(get("/items").accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk());
simple comment instead of downvote would suffice imho
