@ExtendWith (SpringExtension.class) ne fonctionne pas

J'essaie d'utiliser Junit 5 sur un projet Spring-boot 2.x pour tester un contrôleur.

Les éléments suivants fonctionnent bien

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.webAppContextSetup;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@WebMvcTest(TypesController.class)
@RunWith(SpringRunner.class)
public class TypesControllerTest {
    @Autowired
    WebApplicationContext wac;

    @Test
    public void testTypes() throws Exception {
        webAppContextSetup(wac).build().perform(get("/types").accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk()).andExpect(content().contentType("application/json;charset=UTF-8"));
    }

    @EnableWebMvc
    @Configuration
    @ComponentScan(basePackageClasses = { TypesController.class })
    static class Config {
    }
}

Mais si je le change pour utiliser SpringExtention,

..

import org.springframework.test.context.junit.jupiter.SpringExtension;
import org.junit.jupiter.api.extension.ExtendWith;

..
@ExtendWith(SpringExtension.class)
@WebMvcTest(TypesController.class)
public class TypesControllerTest {
..
}

Je reçois l'exception suivante:

Vous ne courez toujours pas avec JUnit 5. Une ligne telle que

org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.Java:57)

montre que. Vous utilisez peut-être toujours le mauvais @Test annotation.
