From 22ff3b4f2e74d005a3f11b3f1a126fab2b98596a Mon Sep 17 00:00:00 2001 From: TurtleWolfe Date: Sun, 5 Jul 2026 02:26:19 +0000 Subject: [PATCH] test: remove vacuous blog-migration integration test (#25) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit src/tests/integration/migration.test.ts (541 lines, 16 tests) imported ZERO application source — only vitest/fs/path — and asserted against inline mock objects it defined itself. It "tested" a blog content-migration subsystem that was never built (issue #25 US4), so it passed regardless of the codebase and gave false coverage confidence. Delete it rather than leave a green test that guards nothing. Surfaced during the #38/#35/#25 gap audit. The named migration feature (US4) is fork-scope, not template scaffolding — see #25. Two sibling integration tests (auto-generation, enhanced-processing) share the same zero-import mock pattern and are flagged separately for a scoping decision rather than swept up here.
