Wiki page of this test tools.

This project give some lite tools for test unit writing. It's base on framework JUnit, DBUnit and Mockito.

If you're using the GitHub for Mac, simply sync your repository and you'll see the new branch.

JUnit features :

@RunWith(Parameterized.class)
public class ParameterizedTest {

  private final MyService service = new MyService();

  @Parameters
  public static Collection<Object[]> datas1() {
    final Collection<Object[]> datas = new ArrayList<Object[]>();

    datas.add(new Object[] { "Paul", "Hello, Paul", 1, new Object[] { "test", Double.valueOf(2.54689) } });
    datas.add(new Object[] { "Jack", "Hello, Jack", 2, new String[] {} });
    datas.add(new Object[] { "my name is Patty  !", "Hello, my name is Patty  !", 5, null });

    return datas;
  }

  @TestParameterized
  public void testGreet(final String name, final String expected, final int cpt, final Object[] vals) {
    System.out.println(cpt + ", " + ToStringBuilder.reflectionToString(vals, ToStringStyle.SHORT_PREFIX_STYLE));
    assertThat(service.greet(name)).isEqualTo(expected);
  }
}

Mockito features :

Based on JUnit rule

public class MockingRuleTest {

  @Rule
  public MockingRule rule = MockingRule.init();

  @Mock
  private MyService mock;

  @Spy
  private MyService spy;

  @Test
  public void testRule() {
    assertThat(MockingRule.init()).isNotNull();

    assertThat(mock).isNotNull();
    assertThat(spy).isNotNull();
  }
}

DBUnit features :

Load datas with @DataSet, automaticly inject EntityManager if defined int class :

@DataSet("entities")
public class DBUnitRuleTest {

  private EntityManager em;

  @Test
  @DataSet("datas/others")
  public void testLoadOthers() {
    assertThat(em).isNotNull();
    final MyEntity entity = em.find(MyEntity.class, 20l);
    assertEquals(Long.valueOf(20), entity.getId());
    assertEquals("Pierre", entity.getName());
  }
}

@DataSet can be defined for the entire class and/or for a specific method.

To activate DBUnit, 3 ways a JUnit rule :

  @Rule
  public DBUnitRule dbUnitRule = DBUnitRule.init();

an abstract class :

public class AbstractDBUnitTestTest extends AbstractDBUnitTest {

a runner :

@RunWith(DBUnitRunner.class)
public class DBUnitRunnerTest {

You can define the rollback strategy with @Transactionnal. You can redefined JPA config with @JpaConfig (by default the unit persistence name is 'pu-test'). note that you can not even change the persistence.xml file name, but soon I hope :)
