[![Coverage Status](https://coveralls.io/repos/github/niqdev/dagger-realm-test/badge.svg?branch=master)](https://coveralls.io/github/niqdev/dagger-realm-test?branch=master)

:tada: Updated with Realm v1.x!! <-- Robolectric/Realm [issue](https://github.com/robolectric/robolectric/issues/1389)

Sample Android application of [Dagger 2](http://google.github.io/dagger/) and [Realm](https://realm.io/docs/java/latest/) tested with [Robolectric](http://robolectric.org/), [Mockito](http://mockito.org/) and [PowerMockito](https://github.com/jayway/powermock).

### Example

```java

@RunWith(RobolectricGradleTestRunner.class)

@Config(application = CustomApplicationTest.class, constants = BuildConfig.class, sdk = 21)

@PowerMockIgnore({"org.mockito.*"})

@PrepareForTest({Injector.class})

public class MessageRepositoryTest {

    @Rule

    public PowerMockRule rule = new PowerMockRule();

    @Inject

    MessageRepository messageRepository;

    @Inject

    DatabaseRealm databaseRealm;

    @Before

    public void setupDagger() {

        ApplicationComponentTest applicationComponentTest = DaggerApplicationComponentTest.builder()

            .applicationContextModuleTest(new ApplicationContextModuleTest())

            .repositoryModuleTest(new RepositoryModuleTest(false))

            .build();

        PowerMockito.mockStatic(Injector.class);

        PowerMockito.when(Injector.getApplicationComponent()).thenReturn(applicationComponentTest);

        ((ApplicationComponentTest) Injector.getApplicationComponent()).inject(this);

    }

    @Test

    public void messageRepository_add() {

        String MESSAGE_UUID = "UUID";

        String MESSAGE_CONTENT = "CONTENT";

        String MESSAGE_INFO = "INFO";

        MessageModel message = new MessageModel();

        message.setUuid(MESSAGE_UUID);

        message.setContent(MESSAGE_CONTENT);

        message.setInfo(MESSAGE_INFO);

        when(databaseRealm.add(message)).thenReturn(message);

        TestSubscriber tester = new TestSubscriber<>();

        messageRepository.add(message).subscribe(tester);

        verify(databaseRealm).add(message);

        tester.assertValue(MESSAGE_UUID);

        tester.assertCompleted();

        tester.assertNoErrors();

    }

    @Test

    public void messageRepository_findAll() {

        MessageModel message1 = MessageModel.newBuilder().content("CONTENT1").build();

        MessageModel message2 = MessageModel.newBuilder().content("CONTENT2").build();

        List messages = Arrays.asList(message1, message2);

        when(databaseRealm.findAll(MessageModel.class)).thenReturn(messages);

        TestSubscriber> tester = new TestSubscriber<>();

        messageRepository.findAll().subscribe(tester);

        tester.assertValue(messages);

        tester.assertCompleted();

        tester.assertNoErrors();

    }

}
