tester-libft is my personal tester for my 42’s libft project. This is not the official tests but only the ones I think are important. The best thing to do is to use the maximum tests/testers to be sure your libft is perfect.
If you run the tests on ubuntu machine (with same version as 42), you can use normal tests. These tests compare original libc’s function with your function.
I also created a “static” version, that doesn’t compare normal libc’s function with yours in special cases, like passing NULL, because the behaviors can be different regarding the OS. To use it, run make srun.
The default structure is:
. |- libft/ |- tester-libft/
You can change this by changing the $(LIBFTDIR) variable in Makefile.
You will need to add a rule in your libft’s Makefile to create a shared library (.so). Here is an example :
so:
$(CC) -nostartfiles -fPIC -c $(CFLAGS) $(SRC)
cc -nostartfiles -shared -o libft.so $(OBJ) -ldlJust run make run and the Makefile will build your libft & launch the tests.
If you want to run “static tests”, run make srun.
If you want to run the tests for a particular function, run make run/srun function_name. (The function_name is the name of your libft’s function, for example ft_isalpha).
The tester-libft uses CuTest for unit testing every function of the libft. It is really simple to use and it takes only 2 files to work. If you want to create your own unit tests or modify mine, you can do so easily.
