android Mockito 升级2.0 发生 AbstractMethodError 异常

最近在研究android单元测试,没想到第一步进坑里了!!!在测试mvp之model的时候使用Mockito mock对象,在初始化一直发生AbstractMethodError异常.不说了先上异常环境.

androidTestImplementation "org.mockito:mockito-core:2.25.0"
androidTestImplementation 'com.google.dexmaker:dexmaker:1.2'
androidTestImplementation 'com.google.dexmaker:dexmaker-mockito:1.2'

---

再上异常:

java.lang.AbstractMethodError: abstract method "org.mockito.plugins.MockMaker$TypeMockability org.mockito.plugins.MockMaker.isTypeMockable(java.lang.Class)"
at org.mockito.internal.util.MockUtil.typeMockabilityOf(MockUtil.java:29)

###初始化方式1:

@RunWith(MockitoJUnitRunner.class)
public class LoginFrgModelTest {

    @Mock
    List testList;
	
	 @Test
    public void doLoginByMsg() {
    
      Mockito.when(testList.get(0)).thenReturn("ssdf");
      String o = (String) testList.get(0);
      Assert.assertEquals(o, "ssdf");

	}
}

###初始化方式2:

public class LoginFrgModelTest {

   @Mock
   List testList;

   @Before
   public void setUp() throws Exception {
   
     MockitoAnnotations.initMocks(this);
   }

   @Test
   public void doLoginByMsg() {
    
     Mockito.when(testList.get(0)).thenReturn("ssdf");
     String o = (String) testList.get(0);
     Assert.assertEquals(o, "ssdf");

   }
}

###初始化方式3:

public class LoginFrgModelTest {
   @Test
   public void doLoginByMsg() {
     List testList = mock(List.class);
     Mockito.when(testList.get(0)).thenReturn("ssdf");
     String o = (String) testList.get(0);
     Assert.assertEquals(o, "ssdf");

   }
}

各种姿势玩遍,都报AbstractMethodError异常.都怀疑我是不是合适玩测试了.最后还是上大谷歌了,果然查到了一丝猫腻,Dexmaker已经不适合在Mockito 2.0版本了!!!

Dexmaker does not support Mockito 2.0 since the definition of 
MockMaker has changed. 

##解决bug
果断怀疑以下两个库有问题了

androidTestImplementation 'com.google.dexmaker:dexmaker:1.2'
androidTestImplementation 'com.google.dexmaker:dexmaker-mockito:1.2'

继续google发现有人写了个兼容Mockito 2.0,果断替换.it worked.

androidTestImplementation "org.mockito:mockito-core:2.25.0"
//androidTestImplementation 'com.google.dexmaker:dexmaker:1.2'
//androidTestImplementation 'com.google.dexmaker:dexmaker-mockito:1.2'
androidTestImplementation 'com.linkedin.dexmaker:dexmaker-mockito:2.25.0'

#完
ps:
网上有说2.0方式二不好用了.没有验证,因为懒…
