Testing 101

So far you've been writing your programs amd running them time and time again doing that. A constant cycle of change-run-repeat until it works.

Which works fine until

you have hundreds of scenarios and inputs
the program takes quite long to run and it starts eating up too much time
you accidently break your program and don't even realize (billions lost, rockets dailing, people dying)
