1. JUnit on the emulator without instrumentation

I would like to write, run, and debug JUnit tests that test non-GUI
code that has dependencies on the Android SDK. Is there a simple way
to do that? I'm aware of the instrumentation mechanism, but that seems
to be geared towards testing GUI code. It is also unclear how to use
the instrumentation mechanism with Eclipse and also the de{*filter*}.
I've tried simply writing tests using the classes in android.test and
running them via AndroidTestRunner invoked from a button click on an
Activity, but I get the following error when I try to run the

W/dalvikvm(  594): VFY: unable to resolve new-instance 8 (Landroid/
test/AndroidTestRunner;) in Lcom/spike/AndroidSpike$2;

For completeness, here is the complete code for the Activity.

package com.spike;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.test.*;

public class AndroidSpike extends Activity {
    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
(R.id.runTestsButton)).setOnClickListener(new OnClickListener() {
                        public void onClick(View v) {
                                AndroidTestRunner runner = new 

2. android test


I am writting unit tests on my Android project.
I would like to test whether a specific dialog window appears when i
click on a button.
For example, I have :
----------------------------------Begin Code

public class MyDialog extends Dialog

public class MyActivity extends Activity


    myButton.setOnClickListener( new OnClickListener()
         public void onClick(View v)
               MyDialog window = new MyDialog(...);


It works fine, but how to test it?

I start my test method, but i don't know how to finish it :

--------------------------------Begin Code
  public void testMyButtonAction()
    startActivity(intent,null, null);
    Activity currentActivity = getActivity();
    myButton = (Button) currentActivity.findViewById(R.id.mybutton);
    assertNotNull(........)   // what is the method to get Dialog
------------------------------- End Code

Somebody can help me please :D
