Junit的：MethodNotFoundException與PowerMock

在運行基於DBUnit的JUnit測試情況下，我得到以下異常：Junit的：MethodNotFoundException與PowerMock

java.lang.RuntimeException: Invoking the beforeTestMethod method on PowerMock test listener [email protected] failed.

我班的樣子：

@RunWith(PowerMockRunner.class) 
public class SampleDbTest extends { 

    /** service mock */ 
    @InjectMocks 
    private TestService testService; 

    /** entity manager. */ 
    EntityManager     entityManager; 

    /** 
    * Sets the up. 
    * 
    * @throws Exception the exception 
    */ 
    @Before 
    public final void setUp() throws Exception { 
     // get entity manager 
     injectField(testService, "entityManager", entityManager); 
    } 
    .... 
    ....

這裏TestService的是無狀態會話Bean接口。我無法在這個奇怪的例外的任何地方找到任何解釋。請讓我知道，如果你有任何想法。

謝謝。

我認爲你使用PowerMock和Mockito的不兼容版本。

如果你看看你的stacktrack，你會發現，這個異常是由PowerMockitoInjectingAnnotationEngine拋出的，而這個類找不到assertNoAnnotations的方法。

最後一個Powermock版本是1.5.6。所以，現在看看這個類的src中的舊版PowerMock（例如1.4.12），你會看到，有調用assertNoAnnotations方法處理。從1.5版本開始，此類不使用此類調用。

最後一個版本的Mockito是1.9.5。現在，如果你看（它被PowerMockitoInjectingAnnotationEngine擴展）的src爲1.9.0版本的Mockito，你會看到，有assertNoAnnotations方法存在。並且，在1.9.5版本中 - 此方法消失。

我想，你會通過更新你使用的框架版本來擺脫這個錯誤。
