Tengo un problema al probar mi aplicación de Android.
Tengo 2 clases testCase, si las ejecuto por separado, no hay problema, las pruebas se ejecutan hasta el final. Pero si hago "clic derecho" en mi proyecto de prueba y elijo "Ejecutar como prueba Junit de Android", recibo un mensaje

 Launching instrumentation android.test.InstrumentationTestRunner on device emulator-5554
 [2012-03-27 15:56:27 - matroussedemaquillageTest] Collecting test information
 [2012-03-27 15:56:31 - matroussedemaquillageTest] Test run failed: Instrumentation run  failed due to 'Process crashed.'

ver más abajo para mis dos clases de prueba:

la primera clase de prueba

package fr.smardine.matroussedemaquillage.test;

import android.test.ActivityInstrumentationTestCase2;
import android.widget.ImageSwitcher;
import fr.smardine.matroussedemaquillage.EntryPoint;

public class EntryPointTest extends
    ActivityInstrumentationTestCase2<EntryPoint> {

private EntryPoint mActivity;
    private ImageSwitcher mSwitcher;

    public EntryPointTest() {
        super("fr.smardine.matroussedemaquillage",
                fr.smardine.matroussedemaquillage.EntryPoint.class);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();
    }

    @Override
    protected void tearDown() throws Exception {
        super.tearDown();
    }

    public void test2() {
        assertEquals(2, 2);
    }
}

y el segundo

package fr.smardine.matroussedemaquillage.test;

import android.test.ActivityInstrumentationTestCase2;
import android.widget.ImageView;
import fr.smardine.matroussedemaquillage.Main;

public class MainTest extends ActivityInstrumentationTestCase2<Main> {

    private Main mActivity;
    private ImageView btRemplir;
    private ImageView btPerime;
    private ImageView btNotes;

    public MainTest() {
        super("fr.smardine.matroussedemaquillage",
                fr.smardine.matroussedemaquillage.Main.class);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();
    }

    @Override
    protected void tearDown() throws Exception {
        super.tearDown();
    }


    public void test1() {
        assertEquals(1, 1);
    }
}

omo puede ver, mi prueba no es tan complicada, incluso si "borro los datos del usuario" cuando inicio mi emulador, hay el mismo mensaje si ejecuto las dos pruebas.
Ah, por cierto, el emulador se ejecuta en Android 2.1 y este es mi archivo AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<instrumentation
    android:name="android.test.InstrumentationTestRunner"
    android:targetPackage="fr.smardine.matroussedemaquillage" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <uses-library android:name="android.test.runner" />
</application>

</manifest>
