Testing spring-boot web-app with thimeleaf

Question

I am trying to write tests to make sure my controllers load my views.

In doing so, I get a "circular view of the path" exception. This is due to the fact that thimelear-species-resolver is not present.

A simple controller method is as follows:

@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), in which case the view is called customer.html . If I change the view name that is different from the @requestMapping value, then I avoid the c error.

How can I provide the ThymeleafViewResolver that spring-boot-autoconfig creates for my tests?

This question says that I have to do this, but I don’t know how ..: How to avoid the "Circular viewing path". Spring MVC test exception

CustomerControllerTest.java

 @RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(classes = Application.class) @WebAppConfiguration public class CustomerControllerTest { @Autowired CustomerController customerController; private MockMvc mockMvc; @Before public void setup(){ // Process mock annotations MockitoAnnotations.initMocks(this); // Setup Spring test in stand-alone mode this.mockMvc = MockMvcBuilders.standaloneSetup(customerController).build(); } @Test public void testLoadCustomerPage() throws Exception{ this.mockMvc.perform(get("/customer")).andExpect(status().isOk()); } } 

An exception

 javax.servlet.ServletException: Circular view path [customer]: would dispatch back to the current handler URL [/customer] again. Check your ViewResolver setup!

Thanks for all the answers in advance ppl!

Answer 1

After brilliant comments here, I changed the controller to the next one and now it 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()); } }

I ended up with this solution. Move the thymeleaf templates directory from src/main/resources to src/main/webapp/WEB-INF . Also adjust prefix in ServletContextTemplateResolver to point to the new location /WEB-INF/templates/
