How to use intent when testing Android classes?

Question

here is some sample code, it seems that it doesn't work for me.

public class CropImageTest extends ActivityInstrumentationTestCase2<CropImage> {

    private Instrumentation mInstrumentation;
    private CropImage mActivity;
    private String filename = "/mnt/sdcard/DCIM/Camera/2011-05-12 09.22.56.jpg";
    private int aspectX = 1;
    private int aspectY = 1;
    private boolean scale = true;

    public CropImageTest() {
        super("hk.com.novare.android.cropimage", CropImage.class);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        this.mInstrumentation = getInstrumentation();
        Intent i = new Intent(mInstrumentation.getContext(), CropImage.class);

        i.putExtra("image-path", filename);
        i.putExtra("aspectY", aspectY);
        i.putExtra("aspectX", aspectX);
        i.putExtra("scale", scale);
        setActivityIntent(i);
        mActivity = this.getActivity();  
    }

    public void testExtras() {
        String str = "";
        str = mActivity.getIntent().getStringExtra("image-path");
        assertEquals(filename, str);
    }
}

error encountered:

Unable to resolve activity for: Intent ( has Extras )

my manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          android:versionCode="1"
          android:versionName="1.0"
          package="hk.com.novare.android.cropimage.tests">

    <uses-sdk android:minSdkVersion="8"/>
    <instrumentation
            android:targetPackage="hk.com.novare.android.cropimage"
            android:name="android.test.InstrumentationTestRunner"/>
    <application
            android:icon="@drawable/icon"
            android:label="@string/app_name">
        <uses-library android:name="android.test.runner"/>
    </application>
</manifest>

I encountered the error above even if I set the constructor -> super's string(a package ) same as the one that I've indicated within this test project's manifest.xml. please help me.

I think all you need to do is use

Intent i = new Intent();

See, for instance, the answers on this thread.

I've done this before, but it doesn't seem to work, I have the same error of "Unable to resolve activity for: Intent {flg=0x10000000 cmp=hk.com.novare.android.cropimage/.CropImage (has extras)}" – Mark Joseph Del Rosario Jun 27 '11 at 01:10
Silly question, I think, given the package name, but is `CropImage` a listed activity in the manifest for hk.com.novare.android.cropimage? – Ted Hopp Jun 27 '11 at 01:57
a forgotten question, should select the closest one, thanks however! :D – Mark Joseph Del Rosario May 02 '12 at 07:11

While creating the intent you are passing getInstrumentation().getContext() which is the test app's context.

what you want is getInstrumentation().getTargetContext() which is the target application's context.

When constructing the Intent, I think instead of mInstrumentation.getContext() you want to call getActivity(). I'm assuming that CropImage class is actually in the package under test, not the test package.

yep, but it is the one that should get and process the extras, so it doesn't make sense. and as the documentation indicates, you must not call getActivity() method before setActivityIntent()! :(( – Mark Joseph Del Rosario Jun 27 '11 at 00:20
