Integration test causing a duplicate entry exception on insert

[stephaneeybert]

I'm running an integration test and get an exception for a duplicate entry exception on insert.

The integration test has been generated by Roo with the database reverse engineering.

I'm using Roo 1.2.1.RELEASE [rev 6eae723]

[stephaneeybert]

Here is the table structure:

| elearning_teacher | CREATE TABLE `elearning_teacher` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`version` int(10) unsigned NOT NULL,
`user_id` int(10) unsigned NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `user_id_2` (`user_id`),
UNIQUE KEY `id` (`id`),
KEY `user_id` (`user_id`),
CONSTRAINT `elearning_teacher_ibfk_1` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=748 DEFAULT CHARSET=latin1 |

[stephaneeybert]

One of the tests that fails:

privileged aspect ElearningTeacherIntegrationTest_Roo_IntegrationTest {

    declare @type: ElearningTeacherIntegrationTest: @RunWith(SpringJUnit4ClassRunner.class);

    declare @type: ElearningTeacherIntegrationTest: @ContextConfiguration(locations = "classpath:/META-INF/spring/applicationContext*.xml");

    declare @type: ElearningTeacherIntegrationTest: @Transactional;

    @Autowired
    private ElearningTeacherDataOnDemand ElearningTeacherIntegrationTest.dod;

    @Test
    public void ElearningTeacherIntegrationTest.testCountElearningTeachers() {
        Assert.assertNotNull("Data on demand for 'ElearningTeacher' failed to initialize correctly", dod.getRandomElearningTeacher());
        long count = ElearningTeacher.countElearningTeachers();
        Assert.assertTrue("Counter for 'ElearningTeacher' incorrectly reported there were no entries", count > 0);
    }

}

[stephaneeybert]

I guess the problem lies with the unique key index

UNIQUE KEY `user_id_2` (`user_id`)

If I look at the domain class in the ElearningTeacher_Roo_DbManaged.aj file

@ManyToOne
@JoinColumn(name = "user_id", referencedColumnName = "id", nullable = false)
private User ElearningTeacher.userId;

we cam see that the JoinColumn annotation does not display the unique=true attribute.

Is it not supported by Roo ?

[stephaneeybert]

I tried changing the annotation to a OneToOne as in:

public class ElearningTeacher {

@OneToOne
@JoinColumn(name = "user_id", referencedColumnName = "id", nullable = false, unique=true)
private User userId;

}

But I still get the same exception.

Was your database empty before running the tests?

[stephaneeybert]

Yes, totally empty. It is being used for integration testing only.

[Alan Stewart]

Would you please try with hsqldb or H2 in memory?

[stephaneeybert]

Hi Alan, thanks for your interest. I shall try it and come back to you.

One question though, since a live database hold no schema before the application is loaded, I guess I cannot reverse engineer from it.

Then, I wonder what step you want me to take for that try.

Should I find a way to create the schema at loading time, from the domain classes ?
