Android studio 模拟RealmObject类出错

在Mockito中进行测试时，我无法理解如何使用模型领域的类。如果该类是从RealmObjec继承的

public class Foo extends RealmObject {

@PrimaryKey
private String PK;

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

public int getNum(){
    return 1;
}
}

包装在模拟测试中

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

即使我穿上了间谍装

 @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中的节没有帮助

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