We know that test driven development is basically for functional testing , in this blog we will test listview using instrumentation method runOnMainSync() that executes a call on application main ui thread.

here is the layout file :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        tools:context=".ListActivity" >

<ListView
android:id="@+id/lvListviewTest"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
</ListView>

</LinearLayout>

Main activity to run Listview and setting adapter :

public class MainActivity extends Activity {
    // Array of strings...
    String[] mobileArray = {"Test1","Test2","Test3","Test4","Test5","Test6","Test7","Test8"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ArrayAdapter myAdapter = new ArrayAdapter<String>(this, R.layout.activity_listview, mobileArray);

        ListView lvListviewTest = (ListView) findViewById(R.id.lvListviewTest);
        lvListviewTest.setAdapter(myAdapter);
    }
}

now its turn to write test case so this is the class to test click on listview :

public class ActivityTests extends
        ActivityInstrumentationTestCase2<Activity>
{
final ListView lvListviewTest = (ListView) mActivity.findViewById(R.id.lvListviewTest);
        assertNotNull("The list was not loaded", lvListviewTest);

        getInstrumentation().runOnMainSync(new Runnable() {
@Override
public void run() {

        lvListviewTest.performItemClick(list.getAdapter().getView(position, null, null),
        position, list.getAdapter().getItemId(position));
        Log.e("click list click"," yes ");
        }

        });

        getInstrumentation().waitForIdleSync();
        }

Here performItemClick method do the click event on listview.
