MVC test with Spring Boot 1.4

This blog describes some of the test improvements in Spring Boot 1.4. Unfortunately it seems that some important informations are missing. What static import is required to use the methods get(), status() and content() from the following example?

@RunWith(SpringRunner.class)
@WebMvcTest(UserVehicleController.class)
public class UserVehicleControllerTests {

    @Autowired
    private MockMvc mvc;

    @MockBean
    private UserVehicleService userVehicleService;

    @Test
    public void getVehicleShouldReturnMakeAndModel() {
        given(this.userVehicleService.getVehicleDetails("sboot"))
            .willReturn(new VehicleDetails("Honda", "Civic"));

        this.mvc.perform(get("/sboot/vehicle")
            .accept(MediaType.TEXT_PLAIN))
            .andExpect(status().isOk())
            .andExpect(content().string("Honda Civic"));
    }
}
