Question

我在对象的字段上定义了很少的自定义注释，如：

public class Person{
     @Accountname 
     String email;
}

@Accountname的实现类：

       @Autowired ValidationService service;    
       @Autowired ClientSession clientSession;

    @Override
    public boolean isValid(final String email, final ConstraintValidatorContext ctx) {

                    if(!service.isAccountValid(email, clientSession)){
                    return false;
                }
            }

我正在尝试为这些注释编写junits。

    @Test
    public void validEmailTest()
    {
        person.setEmail("abc@xyz.com");

        Set<ConstraintViolation<Person>> violations = validatorInstance.getValidator().validateProperty(person, "email");
        Assert.assertEquals(1, violations.size());
    }

但是当我执行测试时它抛出了这个错误：

如果验证器类依赖于会话等服务，那么如何编写junits呢？

Answer 1

这应该单独测试（单位）。

验证的真实逻辑在你的ValidationService中，所以在那里测试它，在AccountnameValidator中只测试那里的逻辑，注入依赖项：

@Mock ValidationService service;    
@Mock ClientSession clientSession;
@InjectMocks AccountnameValidator av = new AccountnameValidator()
//initialize mocks

//example test
when(service.isAccountValid(email, clientSession)).thenReturn(true);
boolean result = av.isValid(email, ctx);
assertTrue(result);

最后，如果您愿意，可以使用反射在电子邮件字段中验证Person类中注释的存在。

使用自动连接依赖项进行测试，例如Validator中的会话
