Простой тест PowerMock дает ошибку, проект студии Android

Question

У меня есть проект в Android Studio. Я хотел бы проверить некоторые функции с каркасами Mockito и PowerMock. Powermock дает initializaton ошибку в простом тесте, как показано ниже:

@RunWith(PowerMockRunner.class) 
@PrepareForTest({RawDataAmFmFrequency.class}) 
public class TestRawDataAmFmFrequency { 
    @Test 
    public void TestEx() { 
    } 

Я получаю ошибку:

java.lang.NoClassDefFoundError: org/powermock/reflect/proxyframework/ClassLoaderRegisterProxyFramework

Я проверил версию моих зависимостей:

testCompile files('libs/mockito-all-2.0.2-beta.jar') 
testCompile files('libs/mockito-core-2.0.5-beta.jar') 
testCompile files('libs/powermock-api-mockito-1.6.5.jar') 
testCompile files('libs/powermock-api-mockito-common-1.6.5.jar') 
testCompile files('libs/powermock-core-1.6.5.jar') 
testCompile files('libs/powermock-module-junit4-1.6.5.jar') 
testCompile files('libs/powermock-module-junit4-common-1.6.5.jar') 
testCompile files('libs/powermock-api-support-1.6.5.jar') 
testCompile files('libs/javassist-3.14.0-ga-1.0.0.jar') 
testCompile files('libs/cglib-2.2.2.jar') 

Mockito работает хорошо , но Powermock все еще дает ошибку.

Пожалуйста, помогите

Answer 1

Я добавил еще одну зависимость: testCompile files('libs/powermock-reflect-1.6.5.jar').

Я также изменил версию javassist на: testCompile files('libs/javassist-3.18.2-GA.jar').

Это решило мою проблему.
