Code review comment for lp:~stevenk/launchpad/bpb-currentcomponent-assertion-part-3

This method is crying out for some comments explaining what it's actually doing and why. I mean, I get that it's setting things up for later tests, but it took me a couple of goes to understand what each bit does. If you can add comments to explain it a bit better, that'd be great.

Also, bigjool's concerns on IRC need to be dealt with.
