testing spring-boot web-app with thymeleaf

Question

I am trying to write tests to make sure that my controllers loads my views. When doing this i get an "circular view path exception". This is due to the thymeleaf-view-resolver not beeing present. A simple controller-method looks like this: ``` @Cacheable("Customers") @RequestMapping(value="/customer", method = RequestMethod.GET) public String customer(Model model) { model.addAttribute("customer", "customer"); return "customer"; } ``` My views are located on `src/main/resources/templates` (autoconfig by spring-boot) and in this exapmle the view is named `customer.html`. If i change the view-name to be different from the value of @requestMapping, then i avoid the error ofc. How can i provide the ThymeleafViewResolver that Spring-boot-autoconfig creates to my tests? This question states that i have to do it, but doesnt say how..: How to avoid the "Circular view path" exception with Spring MVC test CustomerControllerTest.java ``` @RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationC…

After the brilliant comments here i changed the controller to the following, and it now works :)

CustomerControllerTest.java

```
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
public class CustomerControllerTest {

@Autowired
    CustomerController customerController;

private MockMvc mockMvc;

@Autowired
    WebApplicationContext wac;

@Before
    public void setup(){
    
        // Process mock annotations
        MockitoAnnotations.initMocks(this);

// Setup Spring test in webapp-mode (same config as spring-boot)
        this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }

@Test
    public void testLoadCustomerPage() throws Exception{
        this.mockMvc.perform(get("/customer")).andExpect(status().isOk());  
    }
}
```
