Code like a pro
summary
Live coding builds a tiny PHP domain: Sunbed, Towel, Guest classes plus a GuestId value object, with behavior for reserve/occupy, guard clauses and a TowelException when another guest tries to sit. Tests run with PHPUnit (red‑green‑refactor) and autoloading via phpab; tests are unit‑fast so you run them every minute. Demonstrates TDD workflow, immutable value objects, handling object identity (towel ownership), and a second lottery exercise set up for the afternoon.
