From 12af13a7037f25f6c3f9a126d2aa158174181174 Mon Sep 17 00:00:00 2001 From: Kjell Tore Guttormsen Date: Fri, 1 May 2026 18:18:29 +0200 Subject: [PATCH] test(humanizer): JSON backwards-compatibility test (SC-6) [skip-docs] MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Step 10 of v5.1.0 humanizer Wave 4. Adds tests/json-backcompat.test.mjs asserting that --json output of every CLI remains backwards-compatible with the v5.0.0 contract. Coverage strategy mirrors Wave 3 cli-humanizer test discovery: - 4 fixture-deterministic CLIs (scan-orchestrator, posture, token-hotspots-cli, fix-cli) get strict byte-equal byte-equal --json vs frozen tests/snapshots/v5.0.0/ snapshot, with time-varying fields (timestamp, target path, duration_ms, generatedAt, durationMs) normalized. - drift-cli is checked with the same byte-equal contract guarded by an ensureDriftBaseline precondition; the test silently skips when the baseline cannot be created. - 3 environment-aware CLIs (plugin-health-scanner, manifest, whats-active) read live config-cascade state, so frozen snapshots drift as the marketplace evolves. They are verified by mode- equivalence (--json equals --raw) instead — the same approach established in Wave 3 cli-humanizer.test.mjs. A cross-cutting suite asserts --json output of the 4 deterministic CLIs never carries humanizer fields (userImpactCategory, userActionLanguage, relevanceContext) on any finding, walking both top-level findings arrays and scanners[].findings paths. Tests: 739 to 751 (+12 SC-6 cases). Full suite passes.
