UnitTest.c failing?

Hi, I think I saw from somewhere that the unittests can break after updates, but

1. I wasn't sure about that.
2. Was curious what went wrong in the failed tests.
3. Just wanted to maintain the tests.

So hoping to see what exactly went wrong.
Currently Tests 1 and 8 failed. (And there is no test 3)
Edit: Whoops, how ignorant of me, test3 runs at the very end! (Which succeded btw)
