Question

我正在使用TestNG 6.8.8，Mockito 1.9.5和PowerMock 1.5.4。当我模拟最终的void方法时，测试有时会通过，并且有时会因错误UnfinishedStubbingException而失败。

这是PowerMock的错误吗？

public abstract class Parent implements Serializable {
  protected abstract void validate();

  public final void validateSomething() {
    // some code here
  }
}

@PrepareForTest({ Parent.class })
public class ParentTest {
  @Test
  public final void testSomeMethod() {
    Parent parentObj = PowerMockito.mock(Parent.class);
    doNothing().when(parentObj).validateSomething();

    TestCodeThatResultsInCallToParentObj.validateSomething();
  }
}

错误讯息：

org.mockito.exceptions.misusing.UnfinishedStubbingException:
Unfinished stubbing detected here:
-> at org.powermock.api.mockito.internal.PowerMockitoCore.doAnswer(PowerMockitoCore.java:36)
E.g. thenReturn() may be missing.
Examples of correct stubbing:
    when(mock.isOk()).thenReturn(true);
    when(mock.isOk()).thenThrow(exception);
    doThrow(exception).when(mock).someVoidMethod();
Hints:
 1. missing thenReturn()
 2. you are trying to stub a final method, you naughty developer!

您可以使用委托并将该类的执行包装在您的类中。

class ParentWrapper {
    private final Parent delegate;

    ParentWrapper(Parent delegate) { 
        this.delegate = delegate; 
    }

    void validateSth() {
        delegate.validateSth();
    }

}

现在您可以在没有任何Powermock的情况下模拟ParentWrapper。

PowerMockito间歇性地失败，以模拟抽象类的最终void方法
