From 8711fc92db62d571479da68f49f2edf1eb65a98b Mon Sep 17 00:00:00 2001 From: Molecule AI Fullstack Engineer Date: Mon, 18 May 2026 15:15:48 +0000 Subject: [PATCH] test(handlers): add coverage for plugins_listing.go MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fills gaps from #1488 not covered in plugins_test.go: - parseManifestYAML: wrong-type arrays (numbers in tags/skills/runtimes), missing file (bare directory returns fallback name). - listRegistryFiltered: bare plugin dir without plugin.yaml → fallback name. - ListAvailableForWorkspace: runtime-lookup error → unfiltered registry. - ListInstalled: nil docker → 200 []; with runtime-lookup → no panic. - CheckRuntimeCompatibility: container-missing path; compat/incompat separation.
