Yes.

By default all tests in those directories are run.  For the most part 
people create new testcases by copying old ones.  A good simple example 
is gdb.base/step.exp, I'd start with that, copy it to a new file, and go 
from there.  It can be run on its own using "cd build/gdb && make check 
RUNTESTFLAGS=newname.exp"

BTW, what exactly are you testing?  Improving GDB's test coverage is 
always a good thing.
