INSTRUCTIONS

Test norminette > OK 💚 or 💔 KO

norminette ./

Import main test from nephcode repository. Download Libft test & main from :

https://github.com/nephcode/42unitest.git

Please use the flags like cc -flag functionName -o programName

cc -Wall -Wextra -Werror

Functions have a specific test Main in comment. if you want to test the function with argv parameter it is ok

./functionName [paramater]

Check the memory (exemple calloc)

 valgrind --leak-check=full ./calloc_test 5

Makefile

make
