This document introduces Gil Zilberfeld, the founder of TestinGil, and discusses clean code and clean tests. It provides Gil's contact information and links to TestinGil's website and social media profiles. It also lists some characteristics of clean tests, such as showing intent, being focused, and doing exactly what they say. Finally, it discusses test smells like god classes and methods, comments, uncommunicative names, and embedded constants, and how refactoring can help address these smells.

8. Same, same but different
◉ They are not “real” code
◉ Once a test passes, we move to the next one
◉ We don’t go back to tests
◉ We don’t apply the same standards

written by someone who
cares."
Michael Feathers

“Any fool
can write code that a computer

humans can understand.”

20. Clean tests
◉ Show intent
○ How to use the code
○ What is expected when it’s used in a scenario
◉ Focused
○ Do just enough
○ Like SRP!
◉ Do exactly what they say
◉ Abstract implementation details
