Workflow with PFT

unit_tests.c shows you all the tests that are available. Failing a test means that your output and/or return value was not the same as the libc printf. When this happens, there will be a new file, 'results.txt', that holds information about the failed test, the first line of code for the test (most of them are one line anyway), what printf printed, and what ft_printf printed.

How it works, in Brief

The Makefile creates two versions of each unit test function, one that uses ft_printf, and one that uses printf. For each test, it redirects stdout to a file, then compares their return value. If the return value is identical, it opens both files and reads each one byte by byte until both reach EOF. If any single byte differs, the test fails.

Credits

The test method itself was adapted from outdated moulinette test files a buddy gave me, from which the author was [email protected]. The vast majority of code was written by me. The tests prefixed moul_ were adapted from the moulinette test files, the tests with _ftfc_ were adapted from 42FileChecker, and all other tests (so far) were written by me.
