Binaries are outdated, compile
our_[mini|micro]_paint.cand use that as a reference.
Your code should be in a single file micro_paint.c (or mini_paint.c).
You can start test.sh and it will generate random good or bad examples that will be tested by our_micro_paint and your program.
The result of both programs (exit code) are tested and the output is tested with diff.
A 0 indicates it tested a non-valid file and 1 a valid file.
The tests end when an error occur, and you can see the example that caused the error in example_, and the good output in coutput and your output in output.
