(A regex is looking for the phrase```TEST GROUP```).



Each group will run all tests below it (other groups excluded). If you want to create even more distinct test groups, you can create any number of files named XXX_tests.h, each of which has testing functions. These will be able to be run independently of one another. Note that each such file in your workspace will be```#include```d in the testing driver automatically; also, each test function name even across multiple files must be unique. When running test groups or all tests from all files, the code will be compiled only once.
