유효성 검사 주석이있는 빈 속성에 대한 테스트 케이스에서 ConstraintValidationException을 발생시키는 방법은 무엇입니까?

내 콩에 올바른 유효성 검사 주석이 있는지 테스트하려고합니다. 나는 봄 부팅을 사용하고 있습니다. 다음은 테스트 사례의 예입니다.

package com.example.sandbox;

import static org.assertj.core.api.Assertions.assertThatThrownBy;

import javax.validation.ConstraintViolationException;
import javax.validation.Valid;
import javax.validation.constraints.NotNull;

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.validation.annotation.Validated;

@SpringBootTest
class ValidationTest {

    @Test
    void testConstructor() {
        TestedBean bean = new TestedBean(null);

        assertThatThrownBy(() -> checkIfValidated(bean)).isInstanceOf(ConstraintViolationException.class);
    }

    @Test
    void testSetter() {
        TestedBean bean = new TestedBean(null);

        assertThatThrownBy(() -> bean.setSomeProperty(null)).isInstanceOf(ConstraintViolationException.class);
    }

    private void checkIfValidated(@Valid TestedBean bean) {

    }

    @Validated
    class TestedBean {
        @NotNull
        private String someProperty;

        public TestedBean(String someProperty) {
            super();
            this.someProperty = someProperty;
        }

        public String getSomeProperty() {
            return someProperty;
        }

        public void setSomeProperty(@NotNull String someProperty) {
            this.someProperty = someProperty;
        }
    }
}

에 대한 호출 checkIfvalidated()과를 발생 setSomeProperty(null)시킬 것으로 예상하고 ConstraintViolationException테스트는 통과하지만 둘 다 실패합니다.

java.lang.AssertionError:

왜 ConstraintViolationException여기에서 키워 지지 않습니까? Bean 특성에는 @NotNull어노테이션이 있고 Bean 자체는 @Validated있으며 메소드 서명에는 @ValidBean이 필요합니다 .

내 테스트 클래스의 컨텍스트에서 해당 예외를 발생시키는 간단한 방법이 있습니까?

서비스 인터페이스의 메서드 서명에 유효성 검사 주석을 사용하면 모든 것이 예상대로 작동합니다. 차이점이 어디인지 모르겠습니다.

서비스 인터페이스 :

package com.example.sandbox;

import javax.validation.constraints.NotNull;

import org.springframework.validation.annotation.Validated;

@Validated
public interface IService {
    public void setValue(@NotNull String value);
}

서비스 구현 :

package com.example.sandbox;

import org.springframework.stereotype.Service;

@Service
public class SomeService implements IService {
    @Override
    public void setValue(String value) {
        // Do nothing
    }
}

테스트 케이스 :

package com.example.sandbox;

import static org.assertj.core.api.Assertions.assertThatThrownBy;

import javax.validation.ConstraintViolationException;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class SomeServiceTests {
    @Autowired
    IService service;

    @Test
    void testSetValue() {
        assertThatThrownBy(() -> service.setValue(null)).isInstanceOf(ConstraintViolationException.class);
    }
}

==> 테스트를 통과했습니다.

주어진 답변에 따른 작업 코드 :

테스트 클래스 :

@SpringBootTest
class ValidationTest {
    @Autowired
    private Validator validator; // Using the default validator to test property annotations

    @Autowired
    private TestedBeanService service; // Using a service to test method annotations

    @Test
    void testPropertyAnnotations() {
        TestedBean bean = new TestedBean(null);
        Set<ConstraintViolation<TestedBean>> violations = validator.validate(bean);
        assertThat(violations).isNotEmpty();
    }

    @Test
    void testMethodAnnotations() {
        TestedBean bean = new TestedBean(null);
        assertThatThrownBy(() -> service.setBeanProperty(bean, null)).isInstanceOf(ConstraintViolationException.class);
    }
}

테스트 된 콩 :

@Validated
class TestedBean {
    @NotNull
    private String someProperty;

    public TestedBean(String someProperty) {
        super();
        this.someProperty = someProperty;
    }

    public String getSomeProperty() {
        return someProperty;
    }

    public void setSomeProperty(String someProperty) { // No more annotation on setter
        this.someProperty = someProperty;
    }
}

서비스 인터페이스 :

@Validated
public interface TestedBeanService {
    // method annotation on the interface method
    void setBeanProperty(TestedBean bean, @NotNull String someProperty);
}

서비스 구현 :

@Service
public class TestedBeanServiceImpl implements TestedBeanService {

    @Override
    public void setBeanProperty(TestedBean bean, String someProperty) {
        bean.setSomeProperty(someProperty);
    }
}
