Re: IoC registry survives between JUnit tests?
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. Christian.
