Write a single complete C file containing automated unit tests for the

functions from mystring.h$.$ Cover all the types of test cases we have learned as

thoroughly as possible, and organize your tests into functions called from a main

program. Write the main program as well.

You may call the following functions after including a header file "tests.h$"$ where

the first four are identical to those used in the assignments and model solutions.

$$ VERIFY$\_$INT$($expected$,$ test$)$ and VERIFY$\_$STR$($expected$,$ test$)$will

compare the test value to expected; test may be a function call.

$$ VERIFY$\_$NULL$($test$)$ and VERIFY$\_$NOT$\_$NULL$($test$)$will compare the test to

NULL; test may be a function call.

$$ print$\_$summary$()$ prints a summary showing the number of tests passed and

failed; you do not have to count this yourself.

You can choose a testing$-$appropriate value for MAX$\_$STRING$\_$LENGTH here.
