In Grails 3.1.12, I want to unit test a service:
@Transactional
class PlanService {
List<Plan> getPlans(Map params) {
def currentUser = (User)springSecurityService.getCurrentUser()
return Plan.findAllByCompany(currentUser.employer, params)
}
}
Like this:
@TestFor(PlanService)
@Mock([Plan, User, Company])
class PlanServiceSpec extends Specification {
void "Retrieve plan from the current user"() {
setup:
// create and save entities here
when: "the plans are retrieved"
def params = null
def plans = service.getPlans(params)
then: "the result should only include plans associated to the current user's company"
plans.size() == 2
}
Running the test from the console:
grails> test-app my.PlanServiceSpec -unit
Fails with:
my.FundingPlanServiceSpec > Retrieve plan from the current user FAILED
java.lang.IllegalStateException at PlanServiceSpec.groovy:48
and in the test report (HTML):
java.lang.IllegalStateException: No transactionManager was specified.
Using @Transactional or @Rollback requires a valid configured transaction manager.
If you are running in a unit test ensure the test has been properly configured
and that you run the test suite not an individual test method.
Now if I comment out the @Transactional
annotation in the service, the test passes, but that's not the intended implementation. I am able to work around the problem by mocking the transaction manager:
service.transactionManager = Mock(PlatformTransactionManager) {
getTransaction(_) >> Mock(TransactionStatus)
}
But this seems very awkward, if not wrong.
Is there some incantation I forgot to invoke?
EDIT: looks similar to an old bug , but it's been closed more than a year.
Have you tried what a comments says that fixes the problem? If not, try to annotate the test class with:
@TestMixin(DomainClassUnitTestMixin)
and then:
service.transactionManager = getTransactionManager()
Was getting the same error in grails 3.3.2 when trying to test transactional service.
adding DataTest interface solved the issue for me.
class HelloServiceSpec extends Specification implements ServiceUnitTest<HelloService>, DataTest { }
