Próbujesz użyć mockito w moim AndroidTestCase. Dodałem zależności do build.gradle:NPE podczas wywoływania MockitoAnnotations.initMocks() w AndroidTestCase
final DEXMAKER_VERSION = '1.2'
dependencies {
// ...
androidTestCompile "com.google.dexmaker:dexmaker:${DEXMAKER_VERSION}"
androidTestCompile "com.google.dexmaker:dexmaker-mockito:${DEXMAKER_VERSION}"
androidTestCompile 'org.mockito:mockito-core:1.10.19'
}
TestCase z inicjalizacji Mockito:
public class UsersListPresenterTest extends AndroidTestCase {
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
}
public void testInitialize() throws Exception {
}
}
Ale jak tylko mogę dodać żadnego atrybutu do klasy, jeszcze przed dodaniem adnotacji test zacząć katastrofie:
public class UsersListPresenterTest extends AndroidTestCase {
String mockString;
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
}
public void testInitialize() throws Exception {
}
}
z następującymi stacktrace
java.lang.NullPointerException: Attempt to invoke virtual method

Co robię źle?
Jak to działa z testami JUnit 4? Nie ma 'getContext', którego można użyć. – Matthias
@Matthias, używasz InstrumentationRegistry.getTargetContext(). –
Dobrze, już to wymyśliłem. Dzięki. – Matthias
