Swift Testing Code Review

This reviews Swift Testing code for common pitfalls like pre-computed booleans in #expect that lose diagnostics, #require overuse that masks failures, and accidental Cartesian products in parameterized tests. It gates on confirming import Testing is actually present before critiquing, then checks against a focused list: expression capture, error test specificity, zip() versus arguments() mismatches, confirmation for async sequences versus continuations for completion handlers, and serialization choices. The references break down expect versus require, parameterized test patterns, async testing approaches, and suite organization. Use it when reviewing .swift files that import Testing or use @Test annotations. The checklist is opinionated but grounded in real Swift Testing API traps.
