"Programs must be written for people to read, and only incidentally for machines to execute." - Harold Abelson
A program is a building of though The art of programming is the skill of controlling complexity.
"Test doubles are objects that replace real dependencies to enable automated testing. They are the automated testing equivalent of movie stunt people: they take the place of the original since having the real one is expensive or impractical." Excellent analogy by @venkat_s
