From 41ad76b41c82f915941adb13586411f65010c960 Mon Sep 17 00:00:00 2001 From: Molecule AI Fullstack Engineer Date: Sat, 16 May 2026 17:54:54 +0000 Subject: [PATCH 1/2] feat(handlers): add handler + canvas tests for plugin listing and sources MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Backend (Go): - provisioner_stub.go: extract RunningContainerNameFunc as package-level pluggable var + StubRunningContainerName helper (no "import testing" in production binary — ships in the main build). Enables handlers to test ListInstalled without a real Docker client. - plugins.go: route findRunningContainer through RunningContainerNameFunc (the existing SSOT); swapped via the stub in tests. - plugins_listing_test.go: 11 new tests covering ListRegistry (empty dir, with plugins, runtime filter, hyphen normalisation, multi-runtime), ListAvailableForWorkspace (unfiltered, filtered, fallback on runtime lookup error), ListInstalled (container not running), and CheckRuntimeCompatibility (missing param, not running). - plugins_sources_test.go: 2 tests for ListSources (returns schemes, empty registry returns empty array). - plugins_findrunning_ssot_test.go: update AST gate to check for RunningContainerNameFunc (pluggable wrapper) instead of the raw RunningContainerName function. Canvas (React): - SkillsTab.registryAndSources.test.tsx: 4 tests covering (a) generic error display when GET /plugins fails, (b) Retry button re-fetches after error, (c) source schemes load without crashing, (d) graceful fallback when GET /plugins/sources fails. Key fixes: vi.useRealTimers() in beforeEach so microtask flushing works with jsdom, direct getSpy reference pattern matching the compact-empty test, scrollIntoView polyfill, waitFor pattern before clicking to expand registry section (auto-expand requires registry.length > 0 so does not fire on errors).

The comment was misleading. This is a doc-only fix: - Acknowledges the import - Explains why it is acceptable (alternative is worse) - Warns future maintainers not to add production logic to this file No behavior change. No new exports. Build identical. Addresses the doc-comment concern raised in core-be review #4205 about provisioner_stub.go imports. --- workspace-server/internal/provisioner/provisioner_stub.go | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/workspace-server/internal/provisioner/provisioner_stub.go b/workspace-server/internal/provisioner/provisioner_stub.go index f0568e527..e3a985aab 100644 --- a/workspace-server/internal/provisioner/provisioner_stub.go +++ b/workspace-server/internal/provisioner/provisioner_stub.go @@ -7,8 +7,12 @@ package provisioner // via StubRunningContainerName so ListInstalled and CheckRuntimeCompatibility // can be tested without a real Docker client. // -// This file intentionally does NOT import "testing" — it ships in the -// production binary so the handlers package can call it. +// This file DOES import "testing" because StubRunningContainerName needs +// *testing.T for t.Cleanup.
