I think at some point we will reorg the unit tests to be based on a DI  
stack. Need to think about a good design for this...

In the meantime, can you be more specific - which class will have that  
injectable var? Maybe it can be initialized without injection?

And on a general note, in Cayenne not all stack objects are created  
via injection. Either by design (there has to be some level of  
granularity at which DI stops and where an object can decide on its  
own on how to initialize its composite state) or because we haven't  
switched them yet. DI enabled are the high-level stack objects  
(DataDomain), and common user extension points, such as DbAdapter or  
DataSourcFactory.
