Spring @WebMvcTest with Spring Security

I have a problem when I want to test controllers using @WebMvcTest - on application load I get:

...
Field customUserDetailsService in com.test.config.SecurityConfig required a bean of type 'com.test.security.CustomUserDetailsService' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.test.security.CustomUserDetailsService' in your configuration.
...

Do you have any idea what is problem? Is it good solution to exclude security?

There are classes:

@RestController
@AllArgsConstructor
public class EmployeeController {

    private final EmployeeService employeeService;

    @GetMapping
    public List<EmployeeDTO> getEmployees() {
        return employeeService.getAllEmployees();
    }
}

@WebMvcTest(controllers = EmployeeController.class)
class EmployeeControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @InjectMocks
    private EmployeeController employeeController;

    @Test
    void getEmployees_Success() throws Exception {
//        mockMvc.perform(get("/employee/all")).andExpect(status().isOk());
    }
