模拟RealmObject类时出错

Question

在Mockito中测试时，我无法理解如何使用模型Realm的类。如果该类继承自RealmObjec

public class Foo extends RealmObject {

@PrimaryKey
private String PK;

public Stuff getStuff(){
    return new Stuff();
}

public int getNum(){
    return 1;
}
}

以模拟方式包装以进行测试

@Test
public void clearObject(){
    Foo mock = mock(Foo.class);
}

即使我包裹间谍

 @Test
public void SpyOnRealmObject(){
    Foo foo = new Foo();
    Foo spy_foo = spy(foo);
}

运行测试时出错：

    org.mockito.exceptions.base.MockitoException: 
Mockito cannot mock this class: class ru.arvalon.coffeeorder.trash.Foo.

If you're not sure why you're getting this error, please report to the mailing list.

You are seeing this disclaimer because Mockito is configured to create inlined mocks.
You can learn about inline mocks and their limitations under item #39 of the Mockito class javadoc.

build.gradle中的部分没有帮助

android {
testOptions {
    unitTests.all {
        jvmArgs '-noverify'
    }
}
}
