Running playframework tests as a IntelliJ IDEA JUnit run configuration - junit

Question

I've been trying to run the unit tests in a play application from IntelliJ directly from the built in test runner. (To get the nice UI, click through etc.)
This works for very basic FunctionalTest tests and when it starts it gives the following logging:
16:18:08,353 INFO ~ Starting /home/sindrit/projects/testapp/.
16:18:08,370 INFO ~ Module crud is available (/home/sindrit/play-1.2.3/modules/crud)
16:18:08,949 WARN ~ You're running Play! in DEV mode
16:18:10,242 INFO ~ Connected to jdbc:h2:mem:play;MODE=MYSQL;LOCK_MODE=0
16:18:11,033 INFO ~ Application 'testapp' is now started !
Indicating play is actually starting.
However more complicated tests using database access fail with exceptions like this:
java.lang.UnsupportedOperationException: Please annotate your JPA model with #javax.persistence.Entity annotation.

I expect this is because the instrumentation is not working as it does when running play. The same test runs fine in play auto-test.
Through some google searches I've found that I should need at lest the following parameters:
-javaagent:/home/sindrit/play-1.2.3/framework/play-1.2.3.jar
-Dfile.encoding=utf-8
-Dplay.debug=yes
-Dplay.id=test
-Dapplication.path=/home/sindrit/projects/testapp
Has anyone here gotten this to work?
What JVM parameters or classpath or other things do I need to make the IntelliJ test runner emulate the play runtime environment?
If I add play-testrunner.jar to the dependencies I get the following error:

I maybe over simplifying this but it seems you may have forgotten the Entity annotation on your database models.
Your models should look like this.
#Entity
#Table( name = "pkg_load" )
public class PkgLoad extends Model {
}
Or this if you don't want to use the built in ID in model.
#Entity
#Table( name = "pkg_load" )
public class PkgLoad extends GenericModel {
#Id
#GeneratedValue( strategy = GenerationType.IDENTITY )
#Basic( optional = false )
#Column( name = "pkg_load_id" )
public Long pkgLoadId;
}
http://www.playframework.org/documentation/1.2.3/jpa
The Entity annotation is found in the javax.persistence library.
