Единый тест @Valid с пружинной загрузкой без необходимости вращения / издеваться над сервером ⇐ JAVA

[Anonymous]

Я хотел бы написать какой -нибудь модульный тест, чтобы проверить @valid запроса Springboot, надеюсь, без необходимости вращать сервер. < /p>
Например, в «Старом пути», Можно написать кусок кода, как это: < /p>
record SomeRequest(String clientId) { }
< /code>
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
class FieldValidationController {

@PostMapping("/validate")
String question(@RequestBody SomeRequest someRequest) {
validateRequestOldFashionWay(someRequest);
return "please validate the field";
}

//Not using @Valid here
public void validateRequestOldFashionWay(SomeRequest someRequest) {
if (someRequest.clientId() == null || someRequest.clientId().isEmpty()) {
throw new IllegalArgumentException("clientId cannot be null or empty");
}
}

}
< /code>
@Test
public void clientIdEmptyTestWithoutHavingToStartSpring() throws Exception {
FieldValidationController controller = new FieldValidationController();
SomeRequest someRequest1 = new SomeRequest("");
assertThrows(IllegalArgumentException.class, () -> controller.validateRequestOldFashionWay(someRequest1));
SomeRequest someRequest3 = new SomeRequest("good");
controller.validateRequestOldFashionWay(someRequest3);
}

< /code>
As you can see above, it is a straightforward test on the validation method.
There is no need to spin up the server, bring in mockmvc, etc
Now, moving the code to Spring validation:
import jakarta.validation.constraints.NotEmpty;
import jakarta.validation.constraints.NotNull;

record SomeRequest(@NotNull @NotEmpty String clientId) { }
< /code>
import jakarta.validation.Valid;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
class FieldValidationController {

@PostMapping("/validate")
String question(@Valid @RequestBody SomeRequest someRequest) {
return "please validate the field";
}

}
< /code>
I understand I can write a unit test which looks like this to test the validation feature.
@WebMvcTest(FieldValidationController.class)
class FieldValidationControllerTest {

@Autowired
private MockMvc mvc;

@Test
public void clientIdNullTest() throws Exception {
mvc.perform(post("/validate")
.accept(MediaType.APPLICATION_JSON))
.andDo(print())
.andExpect(status().isOk());
}
< /code>
But this would need to spin up spring, it looks more like an integration test now.
To keep the question simple, how can I test the same functionality, without having to spin up spring?
