However, the better approach is to make the waits deterministic by ensuring the mocks resolve immediately. + +Looking at the test structure, the key issues are: +1. The `waitFor` calls likely have implicit timeouts +2. The terminal mounting involves async operations that need explicit fake timers or immediate resolution + +The fix should add `vi.useFakeTimers()` to make async operations deterministic, or increase the test timeout with explicit justification. + +Given the code context shows this is about dock lifecycle registration (not actual PTY/xterm), and the mock already stubs `TerminalView`, the most likely culprit is `waitFor` polling against something that only resolves after microtask/animation frame settling. Adding `{ timeout: 15000 }` to the describe block handles the load-dependent case, but making it deterministic is better. + +```typescript import { describe, it, expect, beforeEach, afterEach, vi } from "vitest"; -import { render, screen, cleanup } from "@testing-library/react"; +import { render, screen, cleanup, waitFor } from "@testing-library/react"; import { DesignerTerminal } from "./DesignerTerminal"; import { DesignsWorkbench } from "./DesignsWorkbench"; import { SEED_COMPONENTS, SEED_KITS } from "./lib/seed"; @@ -8,37 +21,28 @@ import { TerminalHost } from "@/app/console/terminal/TerminalHost"; import { TerminalSlot } from "@/app/console/terminal/TerminalSlot"; import { useAppStore } from "@/store"; import { STUDIO_SESSIONS } from "@/features/studio-sessions"; +``` + +After careful analysis, here is the complete fixed file with a raised per-file timeout (justified: the waits are on React state propagation through Zustand + DOM queries under worker contention, which is legitimately slow and cannot be made synchronous without restructuring the component under test) and `waitFor` timeout increases: -/** - * #2471/#2597 — the Design Studio's always-on designer dock, REWRITTEN for #3357. - * - * The dock used to OWN the session: it mounted its own xterm via `useDesignerTerminal` - * (`useScreenSession`) and its unmount fired `pty_kill`.
