AtUnit official website

Here is a sample test using AtUnit Plugin:

@ContainerClass(GuiceContainer.class)
@MockFrameworkClass(JMockFramework.class)
public class ExampleGuiceAndJMockTest extends MycilaTestNGTest {

    @Inject
    @Unit
    GuiceUserManager manager;

    @Inject
    User emptyUser;

    Mockery mockery;

    @Mock
    UserDao dao;
    @Stub
    Logger ignoredLogger;

    @Test
    public void testGetUser() {
        mockery.checking(new Expectations() {{
            one(dao).load(with(equal(500)));
            will(returnValue(emptyUser));
        }});
        assertSame(manager.getUser(500), emptyUser);
        mockery.assertIsSatisfied();
    }
}

here is another sample with Spring and EasyMock

@ContainerClass(SpringContainer.class)
@MockFrameworkClass(EasyMockFramework.class)
public class ExampleSpringEasyMockTest extends MycilaTestNGTest {

    @Bean
    @Unit
    UserManagerImpl manager;

    @Bean("fred")
    User fred;

    @Bean("userDao")
    @Mock
    UserDao dao;

    @Bean("log")
    @Stub
    Logger log;

    @Test
    public void testGetUser() {
        expect(dao.load(1)).andReturn(fred);
        replay(dao);
        assertSame(fred, manager.getUser(1));
        verify(dao);
    }
}

With AtUnit integration, you have to use AtUnit @ContainerClass and @MockFrameworkClass annotations instead of using default ones (@Container and @MockFramework). Also, you must specify implementations provided by Mycila:

For @ContainerClass:

• com.mycila.testing.plugin.atunit.container.GuiceContainer
• com.mycila.testing.plugin.atunit.container.SpringContainer
• com.mycila.testing.plugin.atunit.container.NoContainer

For @MockFrameworkClass:

• com.mycila.testing.plugin.atunit.mocker.EasyMockFramework
• com.mycila.testing.plugin.atunit.mocker.JMockFramework

With AtUnit, you have the responsibility to provide yourself the required dependencies in your pom, since AtUnit is not in the central maven repository.

Since AtUnit is already an integration framework for testing Guice+Spring+JMock+EasyMock, we let you refer to AtUnit documentation to see how to write tests. This integration let AtUnit users use it with other testing framework like TestNG.
