我如何期望并验证JMockit中的相同方法

Question

有以下课程:

class ToTest{
    @Autowired
    private Service service;

    public String make(){
         //do some calcs
         obj.setParam(param);
         String inverted = service.execute(obj);
         return "<" + inverted.toString() + ">";
    }
}

我想添加一个测试,断言我用一个带有param X的对象调用了service.execute.

我会通过验证来做到这一点.我想模仿这个调用,让它返回一些可测试的东西.我这样做是出于期望.

@Tested
ToTest toTest;
@Injected
Service service;

new NonStrictExpectations(){
   {   
       service.exceute((CertainObject)any)
       result = "b";
   }
};

toTest.make();

new Verifications(){
   {   
       CertainObject obj;
       service.exceute(obj = withCapture())
       assertEquals("a",obj.getParam());
   }
};

我在obj.getParam()上得到一个空指针.显然验证不起作用.如果我删除了它的预期,但我在invert.toString()中得到一个空指针.

你们怎么做这个工作？

以下测试类对我来说工作正常，使用 JMockit 1.4：

public class TempTest
{
    static class CertainObject
    {
        private String param;
        String getParam() { return param; }
        void setParam(String p) { param = p; }
    }

    public interface Service { String execute(CertainObject o); }

    public static class ToTest
    {
        private Service service;

        public String make()
        {
            CertainObject obj = new CertainObject();
            obj.setParam("a");
            String inverted = service.execute(obj);
            return "<" + inverted + ">";
        }
    }

    @Tested ToTest toTest;
    @Injectable Service service;

    @Test
    public void temp()
    {
         new NonStrictExpectations() {{
             service.execute((CertainObject) any);
             result = "b";
         }};

         toTest.make();

         new Verifications() {{
             CertainObject obj;
             service.execute(obj = withCapture());
             assertEquals("a", obj.getParam());
         }};
    }
}

你能展示一个失败的完整示例测试吗？
