mockito 即使在调用方法时验证也失败

我正在测试下面的代码，但是测试用例失败了。第23行给出了InvocationTargetException。如果调用了某个其他mock的方法，返回mock是否有问题？
此外，即使我注解了第23行，下面的第26行也会使verify失败。打开调试器会抛出InvocationTargetException。我只是检查fetchSideThing方法是否被调用过一次。我该怎么做呢？

  1. @Getter
  2. @Setter
  3. public class SideThing {
  4.     int weight;
  6.     SideThing(int weight) {
  7.         this.weight = weight;
  8.     }
  10.     public static SideThing get(int w) {
  11.         return new SideThing(w);
  12.     }
  13. }
  15. public class ThingGrandParent {
  17.     int tgpVal;
  18.     ThingGrandParent(int val) {
  19.         tgpVal = val;
  20.     }
  22.     public ThingParent GpFun(int y) {
  23.         return new ThingParent(y);
  24.     }
  25. }
  27. public class ThingParent {
  29.     SideThing st;
  31.     ThingParent(int x) {
  32.         st = new SideThing(x);
  33.     }
  35.     public SideThing fetchSideThing() {
  36.         return st;
  37.     }
  39.     private int anotherFun(int y) {
  40.         return y;
  41.     }
  42. }
  44. @Getter
  45. @Setter
  46. public class Thing {
  47.     private int size;
  48.     private int name;
  50.     Thing() {}
  52.     int bLogic(int size) throws Exception {
  53.         ThingGrandParent tgp = fun(size);
  54.         SideThing st;
  56.         ThingParent tp = tgp.GpFun(size);
  57.         st = tp.fetchSideThing();
  58.         return st.getWeight();
  59.     }
  61.     public ThingGrandParent fun(int size) {
  62.         return new ThingGrandParent(size);
  63.     }
  64. }
  66. @RunWith(PowerMockRunner.class)
  67. @PowerMockIgnore("javax.management.*")
  68. @PrepareForTest({Thing.class, SideThing.class})
  69. public class ThingTest {
  71.     @Mock
  72.     ThingParent tp;
  73.     @Mock
  74.     ThingGrandParent tgpp;
  76.     Thing t;
  78.     @Before
  79.     public void setup() {
  80.         MockitoAnnotations.initMocks(this);
  81.        t = spy(new Thing()); // does it matter here if `t` is an InjectMocks or a spy?
  82.     }
  84.     @Test
  85.     public void test1() throws Exception {
  86.         when(tgpp.GpFun(anyInt())).thenReturn(tp); // -- line23, why InvocationTargetException?
  88.         assertEquals(4, t.bLogic(4));
  90.         verify(tp, times(1)).fetchSideThing(); //-- line26 InvocationTargetException
  91.     }
  92. }

此外，如代码中所示，如果我对Thing t使用spy或InjectMocks，真的会有什么不同吗？
我已经在setup()中使用了MockitoAnnotations.initMocks(this);，但是它说'initMocks（java.lang.Object）'已经过时了。那么我还应该在这里使用什么呢？
以下是失败消息：

initMocks不应该从你的测试中调用。不确定你为什么要使用PowerMockito，我假设Mockito是通常的选择。删除ThingTest类上的3个注解。
如果您使用JUnit 4，请查看@Rule和Mockito.rule（），例如。

  1. @Rule
  2.   public MockitoRule rule = MockitoJUnit.rule()

编辑：我假设还有一些其他的关键问题，Thing 't'没有tp或tgpp集，它将创建新的对象，这些不是mock。
确保Thing t为spy进行了正确的初始化。也许你应该在设置中添加：一个月一个月？
