JMockit-Throwable不可模拟

问题描述

我升级了org.jmockit:jmockit:1.31 -> org.jmockit:jmockit:1.34，尝试模拟异常时遇到以下错误：Class java.lang.Throwable is not mockable

在Jmockit中进行了哪些更改以不再使模拟可抛出异常成为可能？

Java 11
JMockit 1.34
Testng 6.9.10

测试

@Test
public void HttpStatusWhenFailure(@Injectable CustomresponseException e) throws CustomException {
     new Expectations() {{ 
        ProxyManager.rrun((String) any); result = e;
        e.getHttpStatus(); result = 500;
      }};
            
      Response response = resource.run(YearMonth.Now().toString());
            
      assertEquals(response.getStatus(),500);
}

CustomException

@ApplicationException
public class CustomException extends Exception {

    private static final long serialVersionUID = 100L;

    protected int httpStatus;

    public CustomException(int httpStatus) {
        super();
        this.httpStatus = httpStatus;
    }

    public CustomException(int httpStatus,String message) {
        super(message);
        this.httpStatus = httpStatus;
    }

    public CustomException(int httpStatus,String message,Throwable cause) {
        super(message,cause);
        this.httpStatus = httpStatus;
    }

    public CustomException(int httpStatus,Throwable cause) {
        super(cause);
        this.httpStatus = httpStatus;
    }

    public int getHttpStatus() {
        return httpStatus;
    }
}

解决方法

在此处使用模拟异常有点夸张。该测试应该可以工作（使用真正的异常）

@Test
public void HttpStatusWhenFailure() throws CustomException {

 new Expectations() {{ 
    ProxyManager.rrun((String) any); result = new CustomResponseException(500,"msg");
  }};
        
  Response response = resource.run(YearMonth.now().toString());
        
  assertEquals(response.getStatus(),500);
}

该测试将被视为好像rrun（..）导致抛出CustomResponseException（我相信您的意图）一样。相反，如果您希望它像返回异常（异常）一样起作用，那么您可以在其他SO帖子中找到实现此目的的方法。
