Mockito和Dexmaker的UnsupportedOperationException

最近我一直在与Mockito挣扎。但在勇敢的努力之后,我在没有错误的情况下进行编译,除了特殊情况下的这个:

当我使用Mockito模拟包私有类时,在同一个包中进行测试时,我收到以下错误:

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)
    [...]

这是我的班级:

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);
    }
}

我认为测试编译的第一行没有错误意味着此测试与我尝试模拟的CalendarMonitorServiceConnection类位于同一文件夹中。

最后,我在build.gradle中有这些导入:

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"

我错过了什么?

非常感谢您的回答

这是我尝试模拟的类的代码:

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){
        //[...]
    }
}

答案 0 :(得分:1)

经过一些研究,在我看来:

  • Mockito + Dexmaker 无法模拟包私有类,即使单元测试位于同一个包中也是如此。
  • Powermock 可以模拟package-private类,但前提是单元测试位于同一个包中。

因此,我希望保持我的类包私有的解决方案是使用Powermock。
