java - 如何在java中使用注释相关参数检查自定义运行时异常属性

Question

这是我的类结构

public class OrderRuntimeException extends RuntimeException
{
  private final Field field;

   public OrderManagementServiceRuntimeException(String messege, MyError myError)
  {
    super(messege);
    this.field = field;
  }

}

public Class MyError{

    String name;
    Sttring description;

    public MyError(String name, String description){

        this.name = name;
        this.description = description;
    } 
}

public void getOrders(Order order){
    .......
    throw new  OrderRuntimeException("Invalid Order",new MyError("Illegale","this is an illegal..."))
}

我想用 Junit 测试这个异常和 MeError 类型对象(名称和描述)。我写了这个

public class MyTest {

 @Rule
 public ExpectedException thrown = ExpectedException.none();


@Test(expectedExceptions = OrderRuntimeException.class, expectedExceptionsMessageRegExp = "Invalid Order")
  public void testSetRequestTime_invalidRequestDTOImplType()
  {

    thrown.expect(......);

  }

}

我使用 @Rule .. 来获取 throwed.expect() 功能。但我无法从此测试中获取 MyError 类型对象。如果有人对解决方案有想法，请发表评论或回答。

我认为你可以使用org.hamcrest.Matchers来做出这种类型的断言。

expectedException.expect(OrderRuntimeException.class);
    expectedException.expect(org.hamcrest.Matchers.hasProperty("myError", allOf(
            org.hamcrest.Matchers.hasProperty("name", is("exampleName")),
            org.hamcrest.Matchers.hasProperty("description", is("exampleDescription"))
    )));
