尝试使用自定义答案。

例如:

import org.mockito.Mockito;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;

public class CustomAnswer implements Answer<Object> {

    public Object answer(InvocationOnMock invocation) throws Throwable {

        Answer<Object> answer = null;

        if (isAbstract(invocation.getMethod().getModifiers())) {

            answer = Mockito.RETURNS_DEFAULTS;

        } else {

            answer = Mockito.CALLS_REAL_METHODS;
        }

        return answer.answer(invocation);
    }
}

它将为抽象方法返回mock，为具体方法调用real方法。

您可以在测试中使用匿名类扩展抽象类。 例如(使用Junit 4):

private AbstractClassName classToTest;

@Before
public void preTestSetup()
{
    classToTest = new AbstractClassName() { };
}

// Test the AbstractClassName methods.

您可以实例化一个匿名类，注入您的模拟，然后测试该类。

@RunWith(MockitoJUnitRunner.class)
public class ClassUnderTest_Test {

    private ClassUnderTest classUnderTest;

    @Mock
    MyDependencyService myDependencyService;

    @Before
    public void setUp() throws Exception {
        this.classUnderTest = getInstance();
    }

    private ClassUnderTest getInstance() {
        return new ClassUnderTest() {

            private ClassUnderTest init(
                    MyDependencyService myDependencyService
            ) {
                this.myDependencyService = myDependencyService;
                return this;
            }

            @Override
            protected void myMethodToTest() {
                return super.myMethodToTest();
            }
        }.init(myDependencyService);
    }
}

请记住，必须保护抽象类ClassUnderTest的属性myDependencyService的可见性。

您可以通过使用间谍来实现这一点(尽管使用Mockito 1.8+的最新版本)。

public abstract class MyAbstract {
  public String concrete() {
    return abstractMethod();
  }
  public abstract String abstractMethod();
}

public class MyAbstractImpl extends MyAbstract {
  public String abstractMethod() {
    return null;
  }
}

// your test code below

MyAbstractImpl abstractImpl = spy(new MyAbstractImpl());
doReturn("Blah").when(abstractImpl).abstractMethod();
assertTrue("Blah".equals(abstractImpl.concrete()));

PowerMock的Whitebox.invokeMethod(..)在这种情况下很方便。
