Tap 5.0.9: How to unit test a DAO service with tapetsry-hibernate module
I have created a DAO service which has
HibernateSessionManager (from the tapestry-hibernate
module) as a property.
In AppModule :
public static MyFolderDAO buildMyFolderDAO(
@InjectService(HibernateSessionManager)
HibernateSessionManager sessionManager)
{
MyFolderDAO dao = new
MyFolderDAOHibernate();
dao.setSessionManager(sessionManager);
return dao;
}
The MyFolderDAO service works when it is injected into
a Tapestry page.
I have problem testing the MyFolderDAO service in a
Junit test.
public class MyFolderDAOHibernateTest extends TestCase
{
public void testAddFolder() {
RegistryBuilder builder = new RegistryBuilder();
builder.add(TapestryModule.class);
builder.add(HibernateModule.class);
builder.add(AppModule.class);
Registry registry = builder.build();
registry.performRegistryStartup();
MyFolderDAO dao = registry.getService(myFolderDAO,
MyFolderDAO.class);
MyFolder folder = new MyFolder();
folder.setFoldername(Folder A);
dao.addFolder(folder);
}
}
I get the following exception when I run the above
JUnit test. It looks as though I have not built the
Registry correctly.
It would be very much appreciated if someone can show
me a way.

Re: Tap 5.0.9: How to unit test a DAO service with tapetsry-hibernate module
Thanks for the suggestion!
After reading
http://wiki.apache.org/tapestry/Tapestry5HowToIocAndHibernate
and tried a few combinations. The following works.
1) In AppModule :
define the MyFolderDAO service as before.
2) Create AppModuleTest.java which is only available
in unit test.
public class AppModuleTest
{
public static void bind(ServiceBinder binder)
{
binder.bind(ClassNameLocator.class,
ClassNameLocatorImpl.class);
}
public static void
contributeSymbolSource(OrderedConfigurationSymbolProvider
conf){
//tapestry-hibernate fails without
tapestry.app-name symbol defined
conf.add(AppPackage, new SymbolProvider(){
public String valueForSymbol(String
symbolName){
if(symbolName.equalsIgnoreCase(InternalConstants.TAPESTRY_APP_PACKAGE_PARAM))
return net.sf.folder;
return null;
}
},);
}
}
3) In unit test, create the registry as follow.
RegistryBuilder builder = new RegistryBuilder();
builder.add(HibernateModule.class);
builder.add(AppModule.class);
builder.add(AppModuleTest.class);
Registry registry = builder.build();
registry.performRegistryStartup();
It begs the question on how come the service and
configuration in AppModuleTest.java are not created
automatically in unit test and
they are created automatically in web application.
