+To just execute a test and get back a PASS or FAIL message run:

 ```bash

+To test in GDB use the `-g` flag to enable gdb test mode.

 # Once in the debugger, i.e. at the chevrons prompt, setting a breakpoint could be as follows:

+To speed up the testing loop, if you know your test number you can just run it similar to below:
