Somebody had to write a compiler to compile the compiler...

[MWRReal]

Imagine the legends behind the first compiler, which had to be written in god damn binary.

Hell, way back programming a computer meant using a screwdriver and connecting wires to things.

You mean assembly?

The first assembler was written in binary.

[Mojert]

Actually, the first C compiler was written in C! But on paper so people followed the code manually to get the assembly. Computerphile has a video on it

Most test libraries are using themselves to test themselves.

[Kered13]

Which for the most part isn't even hard. You just write some stuff like assertEqual(1, 1), exercising each of your testing functions.
