I might use a static helper method for this sort of thing.

addTest(testCases, "screen and (color)", "");

Or even struct initialization:

struct TestCase {
   const char* input;
   const char* output;
}

TestCase cases[] = {
  {"screen and color", ""},
};

But I try real hard not to type any more characters than needed, since reading
them again is hard. :)
