From bf918d30d5ecba1e63146a9fab187376f546031b Mon Sep 17 00:00:00 2001 From: Jeremy Date: Thu, 26 Mar 2026 17:15:56 -0500 Subject: [PATCH] test(01-02): add unit tests for scoring functions and taskMetadata passthrough - Add scoreModel, computeTaskRequirements, scoreEligibleModels, getEligibleModels describe blocks to model-router.test.ts (27 new tests) - Add ClassificationResult taskMetadata describe block to complexity-classifier.test.ts (4 new tests: execute-task populated, hook undefined, plan-slice undefined, extractTaskMetadata export) - Add getModelTier unknown-default tests verifying standard tier (not heavy) per D-15 - All 42 model-router tests pass, all 32 complexity-classifier tests pass - All 36 pre-existing capability-router tests continue to pass --- .../gsd/tests/complexity-classifier.test.ts | 29 ++- .../extensions/gsd/tests/model-router.test.ts | 244 +++++++++++++++++- 2 files changed, 270 insertions(+), 3 deletions(-) diff --git a/src/resources/extensions/gsd/tests/complexity-classifier.test.ts b/src/resources/extensions/gsd/tests/complexity-classifier.test.ts index ec53ddcaa..46b39ff4d 100644 --- a/src/resources/extensions/gsd/tests/complexity-classifier.test.ts +++ b/src/resources/extensions/gsd/tests/complexity-classifier.test.ts @@ -1,7 +1,7 @@ -import test from "node:test";
