If I have some piece of data that is used at arbitary times by an

what type of test to run) at start up (the value comes from the
command line or has a hard coded value if not given on the command
line)... what is the "right" way of doing this... I also need to set
this to behavioral values like (make a dry run over a tree of tests
without actually running the test [used to count the size of the
tree... which is generated at runtime based on the call order])

To me it sounds as a good candidate for a singleton.

Or for dependency injectiodependency injectionn of the shared object.

I just relized I sent the last two replies to you privately when I
meant to do so publically... so here it is again:

What is a "dependency injectiodependency"

My guess is that you can abbreviate it "Spring".
