A simple tester for 42's ft_printf project.

Note: this was written in November 2021. It might be that this version becomes outdated in the future, as I have no intention to update it myself. Also, I am not sure if it checks every case which needs to be checked. This tester isn't perfect; I wrote it so I could test my own printf which I was working on, and it helped me, and I am sharing it with the world. I highly encourage you to write your own tester, especially if you are doing the bonus, it was great fun to write and useful.

• fast
• return value checking
• bonus
• does not check undefined behaviour
• if your printf segfaults, the tester segfaults.
• shows your output vs expected output when wrong

just clone this repo in your printf folder.

git clone https://github.com/joppiesaus/ft_printf-tester
cd ft_printf-tester

May you want it somewhere else, just change FT_PRINTF_PATH in the Makefile.

make and run test. When you change your printf, you must make again.

make; ./test

For bonus:

make; ./test b

Further notes: the printf and ft_printf output is saved to output.txt.
