MicronautTest Datasource setup not clean before each execution - spock

Question

I have this micronaut application doing some basic database lookup, just for testing the framework. I have setup the application with flyway database migrations, running a h2 database in my test setup (production uses postgresql). This is used for setting up the schema correctly.
My repository is created using Micronaut data for jpa, so I do not know how to create it without running the tests in full micronaut context.
In my test I try to insert some data in the setup method, before executing some spock tests. When the setup has run once, I would expect it to start with a clean datasource for the next test execution. Since the data will violate a unique constraint, it fails with an sql error in setup for the second test being run. Here's my code:
#MicronautTest()
class CompanyRepositoryTest extends Specification {
#Inject
CompanyRepository repository
#Inject
DataSource dataSource
def sql
def setup() {
sql = new Sql(dataSource: dataSource)
sql.execute(dataSql)
}
def 'test company creation' () {
given:
def name = 'test2'
def orgNumber = '1232429045'
when:
def company = repository.save(new Company(name: name, organizationNumber: orgNumber))
then:
company.id != null
}
#Unroll
def 'get company for #desc'() {
when:
Company result = repository.find(id)
then:
name == null ? result == null : name == result.name
where:
id | name | desc
1 | 'test1' | 'existing company'
2 | null | 'non-existing company'
}
def dataSql = """
insert into company(name, organization_number) values
('test1', '1232429045');
"""
I guess I could create a cleanup block where I execute delete statements, but I see that as a last resort as I would expect the datasource to be clean before each test run.

After a good nights sleep, the obvious answer came to me. Instead of executing the sql through groovy sql,I use entitymanager. Then this works as expected
#Inject
EntityManager entityManager
def setup() {
entityManager.createNativeQuery(dataSql).executeUpdate();
}
