GRAILS-10538: Unit test of service doesn't work with @Transactional annotation

[graemerocher]

Original Reporter: spade
Environment: Not Specified
Version: 2.3
Migrated From: http://jira.grails.org/browse/GRAILS-10538

To reproduce run

{code}
grails create-app new_app
grails create-service Foo

{code}
open %app_home%/test/unit/new_app/FooServiceSpec.groovy and edit the generated test to

{code}
void "test something"() {
expect: service.serviceMethod()
}
{code}

If I now run

{code}
grails test-app
{code}

I get the following output

{code}
| Running 1 unit tests...
| Running 1 unit tests... 1 of 1
| Failure: test something(new_app.FooServiceSpec)
| java.lang.NullPointerException
at new_app.FooServiceSpec.test something(FooServiceSpec.groovy:19)
| Completed 1 unit test, 1 failed in 0m 2s
{code}

If I now go to %app_home%/grails-app/services/new_app/FooService.groovy and remove the @transactional annotation and run

{code}
grails test-app
{code}

I get the following output

{code}
| Running 1 unit tests...
| Running 1 unit tests... 1 of 1
| Failure: test something(new_app.FooServiceSpec)
| Condition not satisfied:
service.serviceMethod()
| |
| null
new_app.FooService@4d905f1f
at new_app.FooServiceSpec.test something(FooServiceSpec.groovy:19)
| Completed 1 unit test, 1 failed in 0m 2s
{code}

and everything works as expected.

Workaround:
If I add the line

{code}
static transactional = true
{code}

to the service instead of the annotation the test still work and I still have the desired behaviour of my service

This is a unit testing issue with the @transactional annotation, not related to the JUnit test runner changes

Still seeing this in my 2.3.7 project. I need to use static transactional = true to get unit tests working

We we're seeing a similar issue in Jesque jobs where we had to add @transactional after upgrading to Hibernate 4 due to the lack of an open Session, and prepending...

@TestMixin(DomainClassUnitTestMixin)

to the class and then adding the TransactionManager manually a la...

jobUnderTest.transactionManager = getTransactionManager()

fixed it for us!

@jamesdh I did that and I'm getting groovy.lang.MissingPropertyException: No such property: transactionManager for class: ehr.IndexDataJob

BTW, this behavior still appears on Grails 2.4.4
