unit tests in a seam-genned app

[matt.drees]

I seam-genned a blank app (called booking), then seam-genned a form (RegisterAction). I wanted to create a unit test (as in the Seam docs (http://docs.jboss.com/seam/1.1.5.GA/reference/en/html/testing.html#d0e13075)), so I copy/pasted the code and tweaked some things:

public class RegisterActionTest {

 @Test
 public void testRegisterAction()
 {
 }

 private EntityManagerFactory emf;

 public EntityManagerFactory getEntityManagerFactory()
 {
 return emf;
 }

 @Configuration(beforeTestClass=true)
 public void initialize()
 {
 emf = Persistence.createEntityManagerFactory("booking");
 }

 @Configuration(afterTestClass=true)
 public void destroy()
 {
 emf.close();
 }
}

Running "ant test" gives me a

javax.naming.NamingException: Local server is not initialized

error in initialize().

If I extend SeamTest (which I think shouldn't be necessary for a unit test), I get a

java.lang.NoClassDefFoundError: net/sf/ehcache/CacheException

in initialize().

I think Seam-gen must not be including an EHCache jar, but I couldn't find where it is supposed to come from (or why the seam-genned integration test doesn't fail).

Also, should unit tests be required to extend SeamTest?

I'm running Seam from cvs.
Thanks for your help.

I think this was a bug in 1.1.1 that is fixed in 1.1.5.

[matt.drees]

I was running from cvs head, so I'm assuming everything in 1.1.5 is in my copy.

But I also tried 1.1.5; same behavior.

Oh I didnt read properly. The reason for the error is that the persistence.xml file is using a JTA datasource, which of course does not exist in a unit test. You need a different persistence.xml if you want to run in a unit test.

[matt.drees]

Ok, thanks.

I'm not sure that any of the examples show how to set up a non-JTA datasource; do they? Is there somewhere else I learn how to do this?

Thanks

Check the HEM docs.

Thanks.

From the HEM docs, I put this together:

 <persistence-unit name="bookingLocal" transaction-type="RESOURCE_LOCAL">
 <properties>
 <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
 <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/>
 <property name="hibernate.connection.username" value="sa"/>
 <property name="hibernate.connection.password" value=""/>
 <property name="hibernate.connection.url" value="jdbc:hsqldb:."/>
 <property name="hibernate.max_fetch_depth" value="3"/>
 </properties>
 </persistence-unit>

I was still getting the NoClassDefFoundError for CacheException, though. So I just grabbed the jar from hibernate core (downloaded separately) and put it in lib. Then it ran fine.

Matt,

I was having the same issue, but I fixed it buy adding the following line to the none jta datasource you set up.

 <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider" />

so your booking local source should read.

<persistence-unit name="bookingLocal" transaction-type="RESOURCE_LOCAL">
 <properties>
 <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
 <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/>
 <property name="hibernate.connection.username" value="sa"/>
 <property name="hibernate.connection.password" value=""/>
 <property name="hibernate.connection.url" value="jdbc:hsqldb:."/>
 <property name="hibernate.max_fetch_depth" value="3"/>
 <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider" />
 </properties>
 </persistence-unit>

I went back and tried the original persistence-test.xml file, which I added the above line to, this also fixed the tests. It appears the the bootstrap bean in the jboss-beans.xml dosn't pick this up.

my persistence-test.xml now reads.

<persistence-unit name="bookings">
 <provider>org.hibernate.ejb.HibernatePersistence</provider>
 <jta-data-source>java:/bookingsTestDatasource</jta-data-source>
 <properties>
 <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
 <property name="hibernate.show_sql" value="true"/>
 <property name="jboss.entity.manager.factory.jndi.name" value="java:/bookingsEntityManagerFactory"/>
 <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider" />
 </properties>
 </persistence-unit>

Hope that makes some sense.

Cool. Thanks Clive.
