I'm trying to run a test for testing a Spring MVC controller. The test compile and runs, but my problem is that I got a PageNotFound warning:
WARN PageNotFound - No mapping found for HTTP request with URI [/] in DispatcherServlet with name ''
My really simple test as follows:
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.view;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration({
"classpath*:/WEB-INF/applicationContext.xml",
"classpath*:/WEB-INF/serviceContext.xml"
})
public class FrontPageControllerTest {
@Autowired
private WebApplicationContext ctx;
private MockMvc mockMvc;
@Before
public void init() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.ctx).build();
}
@Test
public void frontPageController() throws Exception {
this.mockMvc.perform(get("/"))
.andDo(print())
.andExpect(status().isOk())
.andExpect(view().name("searchfrontpage"));
}
}
I'm 100% sure that my webapp maps to the frontpage at "/" and that the name on the view is "searchfrontpage".
Please help!
Technically speaking, tests using MockMvc are in the boundaries between unit and integration tests. They aren't unit tests because endpoints are tested in integration with a Mocked MVC container with mocked inputs and dependencies.
MockMVC class is part of Spring MVC test framework which helps in testing the controllers explicitly starting a Servlet container. In this MockMVC tutorial, we will use it along with Spring boot's WebMvcTest class to execute Junit testcases which tests REST controller methods written for Spring boot 2 hateoas example.
getDispatcherServlet. Return the underlying DispatcherServlet instance that this MockMvc was initialized with. This is intended for use in custom request processing scenario where a request handling component happens to delegate to the DispatcherServlet at runtime and therefore needs to be injected with it.
Another easier way to solve the issue is to change init to this :
mockMvc = MockMvcBuilders.standaloneSetup(new FrontPageController()).build();
My ContextConfiguration was wrong. Correct was:
@ContextConfiguration({
"file:src/main/webapp/WEB-INF/applicationContext.xml",
"file:src/main/webapp/WEB-INF/serviceContext.xml"
})
Now everything works fine.
