Since nobody else has chimed into this question, I'll finish off by saying SenTestingKit really unimpressed me with the complexity (and ugliness) of the setup for my needs. I highly recommend GHUnit which runs in a UI (or on command line if you prefer) and supports using gdb out of the box. It took me a matter of minutes to download and use GHUnit in my project.
It happened to me a few times. I know you switched to GHUnit, but just in case someone is interested: after going around this for a LONG time I realised that Xcode just didn't add the code classes (.m files) in the Compile part of the target, but in the Copy Resources part of the target. Moving it to the right place solved the issue.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
