Java 在JSR303Bean验证单元测试中,如何检查违反了哪些约束
我正试图为bean验证编写一个jUnit测试。 我读 并编写了如下的测试代码 我的环境:Java 在JSR303Bean验证单元测试中,如何检查违反了哪些约束,java,spring,Java,Spring,我正试图为bean验证编写一个jUnit测试。 我读 并编写了如下的测试代码 我的环境: Sprint Boot 2.2.6 爪哇11 AssertJ 3.15.0 目标Bean类: public class Customer { @NotEmpty private String name; @Min(18) private int age; // getter and setter } JUnit测试代码: public class Cust
- Sprint Boot 2.2.6
- 爪哇11
- AssertJ 3.15.0
public class Customer {
@NotEmpty
private String name;
@Min(18)
private int age;
// getter and setter
}
JUnit测试代码:
public class CustomerValidationTest {
private Validator validator = Validation.buildDefaultValidatorFactory().getValidator();
@Test
public void test() {
Customer customer = new Customer(null, 18);
Set<ConstraintViolation<Customer>> violations = validator.validate(customer);
assertThat(violations.size()).isEqualTo(1); // check violations count
// check which constraints are violated by the message of the violation
assertThat(violations).extracting("message").containsOnly("must not be empty");
}
}
公共类CustomerValidationTest{
私有验证器验证器=Validation.buildDefaultValidatorFactory().getValidator();
@试验
公开无效测试(){
客户=新客户(空,18);
设置冲突=验证程序。验证(客户);
assertThat(inflictions.size()).isEqualTo(1);//检查冲突计数
//检查违规消息违反了哪些约束
断言(违规)。提取(“消息”)。仅包含(“不得为空”);
}
}
我想检查违反了哪些约束。现在,我检查违规信息。
有更好的方法吗?本教程将在第7节中介绍测试。。Validations..”这是一种很好的假设预期冲突是集合的一部分的方法
根据您的测试框架,这可能是一个需要遵循的策略
@Test public void validatingObject() {
Car car = new Car();
Set<ConstraintViolation> violations = validator.validate(car);
assertThat(violations.size()).isEqualTo(1);
assertThat(violations)
.anyMatch(havingPropertyPath("customerPropertyPathForCarViolation")
.and(havingMessage("message of desired violation"))); }
@Test public void validatingObject(){
汽车=新车();
设置冲突=验证程序。验证(car);
assertThat(inflictions.size()).isEqualTo(1);
断言(违反)
.anyMatch(具有PropertyPath(“CustomerPropertyPath for CarViolation”)
.和(具有消息(“期望违反的消息”);}

在您的小型测试设置中,您可能能够监督是否准确且仅发生一次违规
assertThat(violations.size()).isEqualTo(1);
及
但是,在更大的设置中,情况可能并非如此。实际上,您想要做的是断言您预期的违规行为存在
使用Testframework junit jupiter api:5.6.2,我的测试如下:
public class CustomerValidationTest {
private static Validator validator;
private static ValidatorFactory factory;
@org.junit.jupiter.api.BeforeEach
void setUp() {
Locale.setDefault(Locale.ENGLISH); //expecting english error messages
factory = Validation.buildDefaultValidatorFactory();
validator = factory.getValidator();
}
@org.junit.jupiter.api.AfterEach
void tearDown() {
factory.close();
}
@org.junit.jupiter.api.Test
public void testContainsEmptyNameViolation() {
Customer customer = new Customer(null, 18);
//perform validation
Set<ConstraintViolation<Customer>> constraintViolations = validator.validate(customer);
boolean hasExpectedPropertyPath = constraintViolations.stream()
.map(ConstraintViolation::getPropertyPath)
.map(Path::toString)
.anyMatch("name"::equals);
boolean hasExpectedViolationMessage = constraintViolations.stream()
.map(ConstraintViolation::getMessage)
.anyMatch("must not be empty"::equals);
assertAll(
() -> assertFalse(constraintViolations.isEmpty()),
() -> assertTrue(hasExpectedPropertyPath),
() -> assertTrue(hasExpectedViolationMessage)
);
公共类CustomerValidationTest{
私有静态验证器;
私营静电加工厂;
@org.junit.jupiter.api.beforeach
无效设置(){
Locale.setDefault(Locale.ENGLISH);//应为英文错误消息
factory=Validation.buildDefaultValidatorFactory();
validator=factory.getValidator();
}
@org.junit.jupiter.api.AfterEach
void tearDown(){
工厂关闭();
}
@org.junit.jupiter.api.Test
public void testContainsEmptyNameViolation(){
客户=新客户(空,18);
//执行验证
设置constraintViolations=validator.validate(客户);
boolean hasExpectedPropertyPath=constraintViolations.stream()
.map(ConstraintViolation::getPropertyPath)
.map(路径::toString)
.anyMatch(“名称”::等于);
boolean hasExpectedViolationMessage=constraintViolations.stream()
.map(ConstraintViolation::getMessage)
.anyMatch(“不得为空”::等于);
资产(
()->assertFalse(constraintViolations.isEmpty()),
()->assertTrue(hasExpectedPropertyPath),
()->assertTrue(hasExpectedViolationMessage)
);
即使您请求AssertJ,我希望这仍然对您有所帮助。在您的小型测试设置中,您可能能够监督是否确实发生了一次违规,并且只发生了一次违规
assertThat(violations.size()).isEqualTo(1);

即使您请求AssertJ,我希望这仍然对您有所帮助。您可以添加一条与字段
@NotEmpty(message=“name应该不为空”)
相关的消息,这将帮助您验证(使用断言)哪个字段违反了约束。您可以添加一条与字段@NotEmpty(message)相关的消息=“名称不应为空”)
,这将帮助您验证(使用断言)哪个字段违反了约束。
