Oh, not a critique of startup or shutdown performance on T5-ioc, but
more of a general principle of unit testing components that
participate in any IoC container. To test the component, you
shouldn't need to use the container, because it's a "unit" test. But
he said he was testing the wiring between components anyway, rather
than the functionality of the units, so my comment isn't as relevant.

I'm not sure what CEG has actually seen here; Registry.shutdown() is
very dramatic, it tears apart the registry (releasing almost
everything to the GC) and informs all of the proxies to shutdown as
well. Could he just be missing the re-creation of the services in
later tests ... Registry startup is very, very fast once all the
underlying classes are instantiated.

FYI, in general, you shouldn't be using the container in your
tests, unless
you're testing the wiring itself. You should be creating the
component/service under test, and constructing it with fakes. This
isn't
absolute but there is a lot more effort/configuration/overhead if
you want
to use the container infrastructure in your unit test, and you
start to have
subtle interactions that might potentially make it more of an
integration
test. You risk testing more than one thing at a time.

Hi!
I have several JUnit tests that instantiate
org.apache.tapestry5.ioc.Registry via the RegistryBuilder before
tests
run.
Now I'm observing that services registered in one test are still
available
in other tests although I did call registry.shutdown(). My test
runner
does
not fork a new JVM.
Calling registry.shutdown() should cause everything to vanish. Is
there
anything that causes one-registry-per-JVM?
