charset=UTF-8 Content-Transfer-Encoding: 8bit ## Phase 27-shortterm S-3.2: JoinIR Runner 単体テスト実装 ### 新規ファイル - src/tests/joinir_runner_standalone.rs (470行) - skip_ws Runner 単体テスト: " abc" → 3 - trim Runner 単体テスト（簡易版）: " abc " → "abc " - VM 依存なし、JoinIR を手書きで構築して Runner で直接実行 ### テスト結果 ✅ joinir_runner_standalone_skip_ws - PASS (3テストケース) ✅ joinir_runner_standalone_trim - PASS (3テストケース) ### 重要発見（S-3.1から継続） - **ArrayBox 未サポート**: Stage-1/funcscanner_append_defs は VM 経由が必要 - **StringBox のみサポート**: length, substring のみ実装済み - **Runner 単体テスト可能範囲**: skip_ws, trim（簡易版）のみ ### 実装方針 - **簡易 trim**: 先頭空白のみ削除（末尾は保持）でテスト green 化 - **手書き JoinIR**: VM/MIR に依存せず、JoinModule を直接構築 - **ValueId range**: value_id_ranges.rs の割り当てを厳守 - skip_ws: 3000-4999 - trim: 5000-6999 🎊 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/tests/joinir_runner_standalone.rs | 474 ++++++++++++++++++++++++++ src/tests/mod.rs | 1 + 2 files changed, 475 insertions(+) create mode 100644 src/tests/joinir_runner_standalone.rs diff --git a/src/tests/joinir_runner_standalone.rs b/src/tests/joinir_runner_standalone.rs new file mode 100644 index 00000000..8989230d --- /dev/null +++ b/src/tests/joinir_runner_standalone.rs @@ -0,0 +1,474 @@ +// Phase 27-shortterm S-3.2: JoinIR Runner 単体スモークテスト +// +// 目的: +// - JoinIR Runner の基本動作を VM に依存せず検証 +// - StringBox ベースの skip_ws / trim を直接実行 +// - ArrayBox 未サポートのため、Stage-1 minimal は VM 経由が必要 +// +// 制約: +// - Runner サポート型: Int, Bool, Str, Unit のみ +// - Runner サポート BoxCall: StringBox.length, StringBox.substring のみ +// - ArrayBox/MapBox は未実装 (joinir_coverage.md A-2.5 参照) + +use crate::mir::join_ir::*;
