Android Robolectric unit testing JVM Core Dump when run all test together

[Armando Ferrero Camargo]

Hi, at the moment I'm trying to test my android application using Robolectric 2.2. The app uses Android + Maven + RoboGuice + Volley etc.

The issue is the next one, i have some test which are working perfectly if i execute them individually through IDEA Intellij or using mvn . This tests are the unitary test of the different fragments contained into a main RoboFragmentActivity. My problem is that when I try to do “mvn clean install”, it start to run the tests, all together, and I get a JVM core dump like this:

#

I can't understand why its not working all together because the tests work individually. Its not a memory leak, the app releases memory correctly.

I have heard that it could be related with Volley + Robolectric but I use Volley 1.0 and Robolectric 2.2, it suppose should work. Some posts that I saw too talks about the shadow objects that Robolectric do related with the callback generated by Volley. Im a little bit stuck with it.

Here is a example of test.

public class DiscoverFanTest extends CustomTestRunner {

    @Inject
    DiscoverFanView discoverFanView;

    private Concert concert;
    private List<Product> products;
    Artist artist;

    @Before
    public void setUp() {
        super.setUp();
        artist = new PrototypeAlbums().getArtists().get(0);
        discoverFanView.setArtist(artist);
        concert = orpheusService.getConcert();
        products = orpheusService.getProducts();

        startFragment(discoverFanView);
    }

    @After
    public void tearDown() {
        TestGuiceModule.tearDown();
        stopFragment(discoverFanView);
        discoverFanView= null;
        concert= null;
        products= null;
        artist= null;
    }

    @Test
    public void testDiscoverFanPresentationNotNull() {
        assert (new DiscoverFanPresentation(discoverFanView.getActivity().getApplicationContext(), discoverFanView) != null);
    }

    @Test
    public void testDiscoverFanImageConcert() {
        ImageView imageConcert = (ImageView) discoverFanView.getView()
                .findViewById(R.id.imageComponentConcertImageView);

        assert (imageConcert != null);
        assertFalse(imageConcert.isClickable());
        assert (imageConcert.getResources() != null);
        assertTrue(imageConcert.getBackground() instanceof Drawable);
    }
}

And this is the CustomTestRunner

@RunWith(RobolectricTestRunner.class)
public class CustomTestRunner {

    protected static NavigationView navigationView;
    protected IService Service = new MockService();
    protected static FragmentManager fragmentManager;

    public void setUp() {

        TestGuiceModule.setUp(this);
        navigationView = Robolectric.buildActivity(navigationView.class).create().start().resume().get();
        fragmentManager = navigationView.getSupportFragmentManager();
    }

    public void tearDown() {
        TestGuiceModule.tearDown();
    }

    public void startFragment(Fragment fragment) {
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction = fragmentTransaction.show(fragment);
        fragmentTransaction.add(fragment, null);
        fragmentTransaction.commit();
    }

    public void stopFragment(Fragment fragment) {
        if (fragment != null) {
            fragmentManager.beginTransaction().remove(fragment).commit();
            fragmentManager = null;
            orpheusNavigationView = null;
        }
    }

}

First of all thanks you, I hope someone could help me because i'm really obsess with it.

Hi,

I get the same error with Robolectric 2 and RoboGuice when I run all tests with Maven clean + install or inside Eclipse IDE:

OutOfMemoryError: PermGen space

Are there any known issues?

[Erich Douglass]

Robolectric rewrites classes at run time, which leads to a lot of PermGen allocations.  You will probably have to increase the Java heap size when running tests. If you use Maven, you can configure the test runner to use a larger heap:

      <plugin>

        <groupId>org.apache.maven.plugins</groupId>

        <artifactId>maven-surefire-plugin</artifactId>

        <version>2.13</version>

        <configuration>

          <argLine>-Xms512m -Xmx1024m -XX:MaxPermSize=256m</argLine>

        </configuration>

      </plugin>

Doesn´t really fix the problem. Also increasing MaxPermSize to 512m doesn´t work. I have 1400 robolectric tests. Nearly the first 1000 tests are running fine, but then I get the OOM PermGen.

OK, was my issue, I set the PermSize at the wrong position. Now my tests run with PermSize of 512m.
