Testing dialog in Android's ActivityUnitTestCase

android, unit-testing

Solution

I find a way to do it, I believe.

The problem was that I needed to extend from ActivityInstrumentationTestCase2 and also do this to avoid problems with the GUI thread.

  final Button uButton = (Button) activity.findViewById(R.id.btnSearchProduct);
    activity.runOnUiThread(new Runnable()
    {
        public void run()
        {
            uButton.performClick();
        }
    });

My only question is how to check the results, since I need to check in which Activity I landed and it's extras?

Problem

I'm trying to test an Activity in android which will show a ProgressDialog and everything works fine in the App, however when I try to use ActivityUnitTestCase and the test causes the Activity to show the dialog it fails with this error: ``` android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application at android.view.ViewRoot.setView(ViewRoot.java:429) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:178) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:91) at android.view.Window$LocalWindowManager.addView(Window.java:392) ``` I was looking at the problem and it seems that the onCreateDialog method of my activity crashes when we try to create it from the test, which I assume is another context, I get that, however I wonder is any of you have been successful on trying such a scenario. This is the code of my onCreateDialog. ``` public Dialog onCreateDialog(final int id) { Dialog dialog; switch (id) { case PROGRESS_BAR: loadingDialog = new ProgressDialog(this); loadingDialog.setMessage("searching for product..."); loadingDialog.setIndeterminate(true); dialog = loadingDialog; break; case INEXISTING_PRODUCT: AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage("Product not found"); builder.setPositiveButton("OK", null); dialog = builder.create(); break; case UNAVAILABLE_SERVICE: AlertDialog.Builder unavailableBuilder = new AlertDialog.Builder(this); unavailableBuilder.setMessage("Service Unavailable"); unavailableBuilder.setPositiveButton("OK", null); dialog = unavailableBuilder.create(); break; default: dialog = super.onCreateDialog(id); } return dialog; } ``` Any ideas?
