I am writing an android application with a tabbed interface. I am using a FragmentActivity with a ActionBar.Tab tabs, with each tab displaying a ListFragment.
In my test case, I am using Robotium 3.6 to perform UI interaction, which is needed to test certain aspects of my fragment's. Each fragment has a separate test method, which tests that the ListView for a fragment has the same content at a set index (0), as the ArrayList<String> which the data is from.
The problem is that while the first two fragments pass their respective tests, the final fragment does not, with the failure trace being that:
junit.framework.AssertionFailedError: AbsListView with index 2 is not available!

Here is the relevant code for the activity being tested:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigator);
PREFERENCES = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
adapterPager = new AdapterPager(getSupportFragmentManager());
viewPager = (ViewPager) findViewById(R.id.pager);
viewPager.setAdapter(adapterPager);
viewPager.setOnPageChangeListener(new SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
super.onPageSelected(position);
getActionBar().setSelectedNavigationItem(position);
}
});
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.addTab(actionBar.newTab().setText(R.string.title_fragment_artists).setTag("artists").setTabListener(this));
actionBar.addTab(actionBar.newTab().setText(R.string.title_fragment_albums).setTag("albums").setTabListener(this));
actionBar.addTab(actionBar.newTab().setText(R.string.title_fragment_songs).setTag("songs").setTabListener(this));
}
The code for each ListFragment is just defining an ArrayList<String>, populating it with dummy content and displaying said content with an ArrayAdapter<String>. Here is the code for the test case:
package com.******.*******.test;
import android.test.ActivityInstrumentationTestCase2;
import com.******.******.ActivityNavigator;
import com.*******.******.FragmentAlbums;
import com.*******.********.FragmentArtists;
import com.*******.******.FragmentSongs;
import com.jayway.android.robotium.solo.Solo;
public class ActivityNavigatorTest extends ActivityInstrumentationTestCase2<ActivityNavigator> {
private Solo solo;
public ActivityNavigatorTest() {
super(ActivityNavigator.class);
}
protected void setUp() throws Exception {
solo = new Solo(getInstrumentation(), getActivity());
}
protected void tearDown() throws Exception {
solo.finishOpenedActivities();
}
public void testFragmentArtistsList() {
solo.assertCurrentActivity("Checking loaded activity is the navigator", ActivityNavigator.class);
solo.clickOnText("Artists");
String contentExpected = FragmentArtists.getArtistList().get(0);
String contentActual = solo.clickInList(0, 0).get(0).getText().toString();
assertEquals("Testing index 0 has same content in ArrayList and ListView", contentExpected, contentActual);
int sizeExpected = FragmentArtists.getArtistList().size();
int sizeActual = solo.getCurrentListViews().get(0).getCount();
assertEquals("Testing same quantity of data in ArrayList and ListView", sizeExpected, sizeActual);
}
public void testFragmentAlbumsList() {
solo.assertCurrentActivity("Checking loaded activity is the navigator", ActivityNavigator.class);
solo.clickOnText("Albums");
String contentExpected = FragmentAlbums.getAlbumList().get(0);
String contentActual = solo.clickInList(0, 1).get(0).getText().toString();
assertEquals("Testing index 0 has same content in ArrayList and ListView", contentExpected, contentActual);
int sizeExpected = FragmentAlbums.getAlbumList().size();
int sizeActual = solo.getCurrentListViews().get(1).getCount();
assertEquals("Testing same quantity of data in ArrayList and ListView", sizeExpected, sizeActual);
}
public void testFragmentSongsList() {
solo.assertCurrentActivity("Checking loaded activity is the navigator", ActivityNavigator.class);
solo.clickOnText("Songs");
String contentExpected = FragmentSongs.getSongList().get(0);
String contentActual = solo.clickInList(0, 2).get(0).getText().toString();
assertEquals("Testing index 0 has same content in ArrayList and ListView", contentExpected, contentActual);
int sizeExpected = FragmentSongs.getSongList().size();
int sizeActual = solo.getCurrentListViews().get(2).getCount();
assertEquals("Testing same quantity of data in ArrayList and ListView", sizeExpected, sizeActual);
}
}
