Testing with SugarORM and Robolectric

Question

I trying to setup an testing environment for my android project. The basic Robolectric setup is done. I used this nice tutorial. If I comment out SugarORM in my Manifest.xml, all test works fine. But If I want to use it with SugarORM I always get this error:

java.lang.NullPointerException at dalvik.system.DexFile$DFEnum.hasMoreElements(DexFile.java:239) at com.orm.SugarDb.getDomainClasses(SugarDb.java:37) at com.orm.SugarDb.createDatabase(SugarDb.java:104) at com.orm.SugarDb.onCreate(SugarDb.java:100) at android.database.sqlite.SQLiteOpenHelper.getDatabaseLocked(SQLiteOpenHelper.java:252) at android.database.sqlite.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:164) at com.orm.Database.getDB(Database.java:18) at com.orm.SugarApp.onTerminate(SugarApp.java:16) at org.robolectric.internal.ParallelUniverse.tearDownApplication(ParallelUniverse.java:133) at org.robolectric.RobolectricTestRunner$2.evaluate(RobolectricTestRunner.java:246) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.robolectric.RobolectricTestRunner$1.evaluate(RobolectricTestRunner.java:158) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:134)

Does everyone have the same problem?

Edit

Maybe it is, because Robolectric shutdown after the test and sugarorm is still not finished. My TestClass

@RunWith(RobolectricTestRunner.class)
@Config(manifest="./src/main/AndroidManifest.xml",emulateSdk=18)
public class MyActivityTest{

    private ActivityController<OnLogActivity> controller = Robolectric.buildActivity(OnLogActivity.class).create().setup();

    @Test
    public void clickingLogin_shouldStartLoginActivity() {
        OnLogActivity activity = controller.get();
        assertTrue(activity.findViewById(R.id.login) instanceof Button);

    }

}

Edit 2.0:

That Robolectric can find the android:name=com.orm.SugarApp you have to create a testfolder with the same package of com.orm and add a test class called TestSugarApp. After that you can test all the stuff.

package com.orm;

...

@RunWith(RobolectricTestRunner.class)
@Config(manifest="./src/main/AndroidManifest.xml",emulateSdk=18)
public class TestSugarApp extends Application
        implements TestLifecycleApplication {

    private ActivityController<OnLogActivity> controller;


    @Test
    public void startEverTestSugarAppAsFirst() {

    }

    @Override
    public void beforeTest(Method method) {
        Log.v("test", "beforeTest");
    }

    @Override
    public void prepareTest(Object test) {
        Log.v("test", "prepareTest");
    }

    @Override
    public void afterTest(Method method) {
        Log.v("test", "afterTest");
    }
}

Ok try next. Add next class to you test code:

public class TestSugarApp
    extends SugarApp
{
    @Override
    public void onCreate() {}

    @Override
    public void onTerminate() {}
}

The class named Test will be loaded and used by Robolectric and you can override some things that are not relevant for testing. I'm trying to prevent to execute code from SugarApp in onCreate and onTerminate (https://github.com/satyan/sugar/blob/master/library/src/com/orm/SugarApp.java).
