recently I've been struggling with Mockito. But after valiant efforts, I made it compile without errors except this one in a particular case :
When I'm mocking a package-private class with Mockito, with a test in the same package, I get the following error :
java.lang.UnsupportedOperationException: cannot proxy inaccessible class class [...].AndroidCalendarGenerator.ManageEventsUI.CalendarMonitorServiceConnection
at com.android.dx.stock.ProxyBuilder.buildProxyClass(ProxyBuilder.java:269)
at com.android.dx.mockito.DexmakerMockMaker.createMock(DexmakerMockMaker.java:56)
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)
[...]
Here is my class :
package [...].AndroidCalendarGenerator.ManageEventsUI;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.runners.MockitoJUnitRunner;
import static org.mockito.Mockito.mock;
@RunWith(MockitoJUnitRunner.class)
public class CalendarMonitorServiceConnectionTest {
@Test
public void testOne() {
CalendarMonitorServiceConnection c1 = new CalendarMonitorServiceConnection(null);
CalendarMonitorServiceConnection c = mock(CalendarMonitorServiceConnection.class);
}
}
I think that the first line of the test compiling without errors means that this test is in the same folder as the CalendarMonitorServiceConnection
class that I try to mock.
Finally, I have those imports in my build.gradle :
androidTestCompile 'junit:junit:4.12'
androidTestCompile 'org.mockito:mockito-core:1.10.19'
androidTestCompile "com.crittercism.dexmaker:dexmaker:1.4"
androidTestCompile "com.crittercism.dexmaker:dexmaker-mockito:1.4"
androidTestCompile "com.crittercism.dexmaker:dexmaker-dx:1.4"
What am I missing ?
Thanks a lot for your answers
EDIT
Here's the code of the class I try to mock :
package [...].AndroidCalendarGenerator.ManageEventsUI;
import android.content.ComponentName;
import android.content.ServiceConnection;
import android.os.IBinder;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import [...].AndroidCalendarGenerator.CalendarEventMonitor;
import [...].AndroidCalendarGenerator.Event;
import [...].AndroidCalendarGenerator.EventChangeListener;
class CalendarMonitorServiceConnection implements ServiceConnection {
private CalendarEventMonitor mMonitor;
private EventListViewAdapter mEventListViewAdapter;
CalendarMonitorServiceConnection(EventListViewAdapter eventListViewAdapter) {
mEventListViewAdapter = eventListViewAdapter;
}
/**
* Custom event change listener that defines what to do in case of changes in the calendar
*/
private class CustomEventChangeListener implements EventChangeListener {
@Override
public void onEventActivated(Event event) {
//[...]
}
@Override
public void onEventRemoved(Event event) {
//[...]
}
@Override
public void onEventListChanged() {
//[...]
}
}
/**
* Pulls data for next 30 days and send it to the adapter
*/
private void sendNextThirtyDaysEventsToAdapter() {
//[...]
}
@Override
public void onServiceConnected(ComponentName className,
IBinder service){
//[...]
}
@Override
public void onServiceDisconnected(ComponentName arg0){
//[...]
}
}
after some research, it seems to me that :
Therefore the solution, as I want to keep my class package-private, is to use Powermock.

I'll update the post as I try Powemock. Or if someone can agree or correct my answer.
