import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.test.web.servlet.MockMvc;

import static org.hamcrest.Matchers.containsString;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;


@WebMvcTest(HomeController.class)
public class HomeControllerTest {
    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testHomePage() throws Exception {
        mockMvc.perform(get("/"))
                .andExpect(status().isOk())
                .andExpect(view().name("home"))
                .andExpect(content().string(
                        containsString("Welcome to...")));

Answer 1

I had the same editor error with 2021.3.1 (Ultimate Edition) version. You can ignore that specific point of error adding @SuppressWarnings tag:

@SuppressWarnings("SpringJavaInjectionPointsAutowiringInspection")
@Autowired
private MockMvc mockMvc;

This can be generated too with editor assistance: Right click over the variable > Show context actions > Inspection 'Incorrect injection point autowiring in Spring bean components' options > Suppress for field

Another way is to update the editor. Currently i'm using 2022.2.2 and the error is not detected.
