ft_printf-test

IT IS NOT NORM COMPLIANT

Description

ft_printf-test is a testing suite for ft_printf. Used for testing all formatters and flags using gtest (Google Test).

See Detailed description for list of tests.

Instructions

Before testing

1. clone your ft_printf into ft_printf folder
2. In Makefile, set FT_PRINTF_INC to the path of your ft_printf/include folder (or any other folder with ft_printf.h in it)

Testing mandatory part

./test.sh

Testing bonus part

./test.sh bonus

Resources

• GoogleTest User’s Guide

AI Usage

Important

All AI code was used after careful analysis.

Google Gemini

Gemini was used while deciding what flags to test with a given formatter.

GitHub Copilot

AI inline suggestions were used for repetitive tasks, such as:

• Writing #includes
• Rewriting tests for different formatters (using existing tests from another formatter as a template)

Tip

gtest might ignore % in test names
Most tests focus around one formatter/flag
All tests for bonus are suffixed _bonus
