Hello again,
So I've been experimenting more with Qi4j. Loving it so far. One of
the things that I wanted to do was to create Nameable entities. I saw
it done in some of the sample code and wanted to give it a go on my own
to get a feel for how constraints fit. So here's my Nameable type
public interface Nameable {
@NonEmptyString Property<String> name();
}
and a test for it, to make sure that the name can't be set to something
other than something valid
public class NameableTest extends AbstractQi4jTest {
@Test
public void assertNameCannotBeSetToNull() throws
ConcurrentEntityModificationException, UnitOfWorkCompletionException {
UnitOfWork uow = unitOfWorkFactory.newUnitOfWork();
Nameable nameable = uow.newEntity(Nameable.class);
nameable.name().set(null);
uow.complete();
}
@Test
public void assertNameCannotBeSetToEmptyString() throws
ConcurrentEntityModificationException, UnitOfWorkCompletionException {
UnitOfWork uow = unitOfWorkFactory.newUnitOfWork();
Nameable nameable = uow.newEntity(Nameable.class);
nameable.name().set("");
uow.complete();
}
@Test
public void assertNameCannotBeSetToStringWithOnlyWhitespace() throws
ConcurrentEntityModificationException, UnitOfWorkCompletionException {
UnitOfWork uow = unitOfWorkFactory.newUnitOfWork();
Nameable nameable = uow.newEntity(Nameable.class);
nameable.name().set(" \t \n");
uow.complete();
}
@Test
public void assertNameCannotBeLeftUnset() throws
ConcurrentEntityModificationException, UnitOfWorkCompletionException {
UnitOfWork uow = unitOfWorkFactory.newUnitOfWork();
uow.newEntity(Nameable.class);
uow.complete();
}
@SuppressWarnings("unchecked")
public void assemble(ModuleAssembly module) throws AssemblyException {
module.addComposites(NameableEntity.class);
module.addServices(UuidIdentityGeneratorService.class,
MemoryEntityStoreService.class);
}
@Constraints( { NotNullConstraint.class,
MinLengthConstraint.class,
InstanceOfConstraint.class } )
static interface NameableEntity extends Nameable, EntityComposite,
ValidatableAbstractComposite {}
}
And to my surprise, all the tests pass, even though they shouldn't. I
should be getting some kind of constraint violation exception but I'm
not. What am I doing wrong?
Thanks,
Rich
