Mockito - Android - Throwing ExceptionIninitializerError

Question

这是我的代码：

    import org.mockito.Mockito;

    public void testOnPrepareOptionsMenu() {

        Menu aMenu = null;
        DrawerLayout drawerLayoutMock = Mockito.spy(drawerLayout);
        Mockito.when(drawerLayoutMock.isDrawerOpen(Gravity.LEFT)).thenReturn(true);
        boolean menuPrepared = homeViewController.onPrepareOptionsMenu(aMenu);
        assertTrue("Menu shall be prepared", menuPrepared);
        assertNotNull("Menu shall exist", aMenu);

        Mockito.when(drawerLayoutMock.isDrawerOpen(Gravity.LEFT)).thenReturn(false);
        menuPrepared = homeViewController.onPrepareOptionsMenu(aMenu);
        assertFalse("Menu shall not prepared when drawer is closed", menuPrepared);

    }

测试在Mockito.spy（drawerLayout）行崩溃。

Answer 1

我忘了将以下内容添加到libs文件夹中：

http://dexmaker.googlecode.com/files/dexmaker-1.0.jar http://dexmaker.googlecode.com/files/dexmaker-mockito-1.0.jar

另外，我必须将它添加到setup（）方法：

System.setProperty(
            "dexmaker.dexcache",
            getInstrumentation().getTargetContext().getCacheDir().getPath());
