ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

Are you running it in the simulator? Based on the answer here:

XCode 4.3 – Build error "missing required architecture armv7"

your testing framework will not run properly on the iphone.
