Question

我正在使用Robolectric 3.3.2和PowerMock对最终类进行单元测试。

@RunWith(RobolectricTestRunner.class)
@Config(sdk = 23)
@PrepareForTest({ FinalClass.class})
public class FragmentTest {

    private TestFragment mFragment;
    private TestActivity mActivity;

    private FinalClass mFinalClassMock;

    @Before
    public void setUp() throws Exception{

        mFinalClassMock = PowerMockito.mock(FinalClass.class);
        PowerMockito.whenNew(FinalClass.class).withAnyArguments()
                    .thenReturn(mFinalClassMock);
        mActivity = Robolectric.buildActivity(TestActivity.class)
                            .create().start().resume().get();
        mFragment = new TestFragment();

    }
}

失败，但有以下异常。

java.lang.IllegalArgumentException：无法继承最终类类com.android.contacts.common.preference.ContactsPreferences 在org.mockito.cglib.proxy.Enhancer.generateClass（Enhancer.java:447）在org.mockito.cglib.core.DefaultGeneratorStrategy.generate（DefaultGeneratorStrategy.java:25）在org.mockito.cglib.core.AbstractClassGenerator.create（AbstractClassGenerator.java:217）在org.mockito.cglib.proxy.Enhancer.createHelper(Enhancer.java:378）在org.mockito.cglib.proxy.Enhancer.createClass（Enhancer.java:318）在org.powermock.api.mockito.repackaged.ClassImposterizer.createProxyClass（ClassImposterizer.java:123）在org.powermock.api.mockito.repackaged.ClassImposterizer.imposterise（ClassImposterizer.java:57）在org.powermock.api.mockito.internal.mockcreation.MockCreator.createMethodInvocationControl（MockCreator.java:111）在org.powermock.api.mockito.internal.mockcreation.MockCreator.mock（MockCreator.java:59）在org.powermock.api.mockito.PowerMockito.mock（PowerMockito.java:143）

我使用的是JUNIT 4.12和Powermock 1.6.4。根据另一篇文章的建议更改了junit和powermock的版本，但没有成功。最近有人遇到过这个问题吗？

Answer 1

在类中添加规则似乎可以解决问题

@Rule
public PowerMockRule rule = new PowerMockRule();

PowerMock无法初始化最终课程
