Question

I am trying to get some basic unit tests up and running on the Play! framework using the Siena persistence library with GAE as the intended deployment target.

I have the project configured properly and can deploy the app to GAE. I created a basic domain object:

public class User extends Model {

    @Id(Generator.AUTO_INCREMENT)
    public Long id;

    @Column("first_name")
    public String firstName;

    @Column("last_name")
    public String lastName;

    @Column("email")
    public String email;

    public User(String firstName, String lastName, String email) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.email = email;
    }

    public static Query<User> all() {
        return Model.all(User.class);
    }

}

and a basic unit test:

public class BasicTest extends UnitTest {

    @Before
    public void setup() {
        Fixtures.deleteAll();
    }


    @Test
    public void canCreateUser() {
        new User("Jason","Miesionczek","[e-mail]").insert();

        User user = User.all().fetch().get(0);

        assertNotNull(user);
        assertEquals(1,User.all().count());
    }

}

I understand that in Play! 1.0.3, Fixtures support for Siena is not there yet, which should be fixed in 1.1, but in the mean time, what should i use instead of Fixtures.deleteAll() to clear the test db before each test?

Right now my second assertion fails because the database retains the previously inserted records.

You would need to do a delete per table. E.g:

Model.all(User.class).delete();
