Review Summary
| # | Dimension | Verdict |
|---|---|---|
| 13 | Test Completeness & Coverage | 🟡 1 MODERATE |
| 16 | Naming & Conventions | 🔵 1 NIT |
✅ 19/21 dimensions clean.
- Test Completeness —
nullinput behavior is unspecified/untested; unclosed-quote silently discards the token (non-obvious, no regression guard) - Naming — typo
SeperateTokens→SeparateTokensin one test method name
Otherwise this is a solid, well-structured addition: assertions follow the project's MSTest conventions, Assert.IsEmpty/Assert.HasCount are consistent with the codebase, BannedSymbols.txt (no AwesomeAssertions) is respected, tests are properly isolated with no shared state, and the happy-path and whitespace/quoting coverage is good.
