I wrote a simplest test based on
android.test.ActivityInstrumentationTestCase2.
[sourcecode language="java"]
package andtest.threads.asynctask;
import java.util.concurrent.ExecutionException;
import andtest.R;
import andtest.threads.asynctask.AsyncTaskDemo;
import andtest.threads.asynctask.AsyncTaskDemoActivity;
import android.test.ActivityInstrumentationTestCase2;
import android.test.UiThreadTest;
import android.widget.Button;
public class AsyncTaskDemoTest3 extends
ActivityInstrumentationTestCase2<AsyncTaskDemoActivity> {
public AsyncTaskDemoTest3() {
super("andtest.threads.asynctask", AsyncTaskDemoActivity.class);
}
protected void setUp() throws Exception {
super.setUp();
}
protected void tearDown() throws Exception {
super.tearDown();
}
@UiThreadTest
public final void testExecute() {
Button btnStart = (Button)
getActivity().findViewById(R.id.Button01);
assertNotNull(btnStart);
btnStart.performClick();
}
}
[/sourcecode]
Whenever I try to run it I got:
-----------------
java.lang.RuntimeException: This method can not be called from the
main application thread
at
android.app.Instrumentation.validateNotAppThread(Instrumentation.java:
1500)
at android.app.Instrumentation.startActivitySync(Instrumentation.java:
439)

android.test.InstrumentationTestCase.launchActivityWithIntent(InstrumentationTestCase.java:

87)
at
andtest.threads.asynctask.AsyncTaskDemoTest3.testExecute(AsyncTaskDemoTest3.java:
36)
. . .
Based on error message I thought that possible a problem in calling
'getActivity()' from main UI thread (ridiculous), so I removed
annotation line
@UiThreadTest
Now I got the error:
----------------
java.lang.RuntimeException: Unable to resolve activity for: Intent

comp={andtest.threads.asynctask/

. . .
Any ideas?
