When I read the first part of this sentence I thought ("one builder,
several steps, build, then upload"), when I read the second part I got
completely lost :)

While this part gives a bit of insight into your configration, a bit
more information how your build and testing builders are related would
really be appreciated.  If for some reasons you can't share your set,
maybe you could write a pseudo-setup that has essential links in it?

This would only use if your builders are all running on the same
machine.  Otherwise, be prepared for surprises.
