Swift Testing: A testing framework for modern Swift
summary
A new Swift testing framework uses @test / @suite macros and runtime macros like pound expect / pound require to test an RPN stack (push, pop throws on empty) and an async timesTwo method; expect records failures and continues while require halts subsequent checks, parameterized tests run each case independently (maximum two parameters), suites run in parallel/random order unless marked serialized, supports knownIssue skipping and timeLimit, requires Swift 6 and has limited CLI tag filtering; custom macros add compile-time cost.
