Is it possible to unit test a sequence in a domain object?

[marcopas]

Hi there,

i was wondering if it possible to unit test a sequence that is
configured in my domain object like this:

    static mapping = {
        // sequence generator for handing out unique transaction id's
        transactionId generator:'sequence',
params:[sequence:'seq_transaction_id']
    }

Whatever i do the sequence stays 'null'

I am using Grails 2.0.4 + spock + build-test-data plugin.

What is it that you want to unit test?  Do you want to test that the
sequence generator is generating what you expect?

Hi Jeff,

I am using the domain object inside a service. So when a new object is
persisted inside the service i expect the sequence to give my object a
unique value in the mentioned property.
I placed a unique constaint on the property but this is offcourse a
stupid one :) But anyway.. I am testing a service that persists an
object but uses the returned generated id in the further processing.
Guess that i have to split up things and make things more modular so i
can test it correctly without the dependency on the sequence
generation.

Any suggestion on how i could unit test services etc that use the
domain object with a sequence in it? Or do i have make an integration
test for this?

class Transaction {
    Long transactionId          // unique auto generated transaction id
    // .. code omitted
    static mapping = {
        // sequence generator for handing out unique transaction id's
        transactionId generator:'sequence',
params:[sequence:'seq_transaction_id']
    }
}

The following test will throw an error on the domain object for the
fact that transactionId may not be nullable.

@Build(Transaction)
@TestFor(Transaction)
class TransactionSpec extends Specification {
    def "simple test"() {
        when:
        Transaction transaction = Transaction.build()
        transaction.save()

        then:
        true
    }
}

I forgot to mention that every test that uses the Transaction domain
object which has a sequence it will fail, this for the simple fact
that storing a transaction will give a validation error that the
sequence property may not be null..
I see no way on how to bypass this..
