When I run the following code:
public class ActivityTest extends ActivityInstrumentationTestCase2<MainActivity> { .... public void testCanCreateMockito() { List mockedList = Mockito.mock(List.class); } } I get the following exceptions:
java.lang.ExceptionInInitializerError at org.mockito.internal.creation.cglib.ClassImposterizer.createProxyClass(ClassImposterizer.java:95) at org.mockito.internal.creation.cglib.ClassImposterizer.imposterise(ClassImposterizer.java:57) at org.mockito.internal.creation.cglib.ClassImposterizer.imposterise(ClassImposterizer.java:49) at org.mockito.internal.creation.cglib.CglibMockMaker.createMock(CglibMockMaker.java:24) at org.mockito.internal.util.MockUtil.createMock(MockUtil.java:33) at org.mockito.internal.MockitoCore.mock(MockitoCore.java:59) at org.mockito.Mockito.mock(Mockito.java:1285) at org.mockito.Mockito.mock(Mockito.java:1163) at com.acesounderglass.hungertracker.ActivityTest.testCanCreateMockito(ActivityTest.java:60) at android.test.InstrumentationTestCase.runMethod(InstrumentationTestCase.java:214) at android.test.InstrumentationTestCase.runTest(InstrumentationTestCase.java:199) at android.test.ActivityInstrumentationTestCase2.runTest(ActivityInstrumentationTestCase2.java:192) at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:191) at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:176) at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:555) at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1837) Caused by: org.mockito.cglib.core.CodeGenerationException: java.lang.reflect.InvocationTargetException-->null at org.mockito.cglib.core.AbstractClassGenerator.create(AbstractClassGenerator.java:238) at org.mockito.cglib.core.KeyFactory$Generator.create(KeyFactory.java:145) at org.mockito.cglib.core.KeyFactory.create(KeyFactory.java:117) at org.mockito.cglib.core.KeyFactory.create(KeyFactory.java:109) at org.mockito.cglib.core.KeyFactory.create(KeyFactory.java:105) at org.mockito.cglib.proxy.Enhancer.<clinit>(Enhancer.java:70) ... 23 more Caused by: java.lang.reflect.InvocationTargetException at org.mockito.cglib.core.ReflectUtils.defineClass(ReflectUtils.java:385) at org.mockito.cglib.core.AbstractClassGenerator.create(AbstractClassGenerator.java:220) ... 28 more Caused by: java.lang.UnsupportedOperationException: can't load this type of class file at java.lang.ClassLoader.defineClass(ClassLoader.java:300) ... 32 more This occurs with any class, List was just an easy example. My gradle dependencies are:
dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:21.0.0' androidTestCompile "org.mockito:mockito-core:1.+" androidTestCompile files('libs/dexmaker-mockito-1.0.jar') androidTestCompile files('libs/dexmaker-1.0.jar') } I've upgraded gradle to 1.1, tried using the experimental unit test feature and not, nothing seems to make a difference. What's going on?

initMocks(this) method has to called to initialize annotated fields.
Mockito verifyZeroInteractions() method It verifies that no interaction has occurred on the given mocks. It also detects the invocations that have occurred before the test method, for example, in setup(), @Before method or the constructor.
@Mock Annotation We can use @Mock to create and inject mocked instances without having to call Mockito.
I received this error when I was missing the two dexmaker dependencies.
Adding these lines to the app/gradle.build file is working for me.
androidTestCompile 'org.mockito:mockito-core:1.10.19' androidTestCompile 'com.google.dexmaker:dexmaker:1.2' androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.2' I am also using Android Studio and have found it to be a good idea to restart AS after altering the dependencies.
