+**Biome rules to follow when writing code** (these cause errors if violated):
+- Use string literals (`'text'`) NOT template literals (`` `text` ``) when there are no interpolations
+- Avoid unnecessary `catch` bindings — use `catch {` not `catch (e) {` when `e` is unused
+- Keep imports organized and remove unused imports
+- Always use block statements with braces — `if (x) { break; }` not `if (x) break;`

+# Skill: VS Code Extension E2E Testing for Logic Apps
+
+## Overview
+E2E tests for the Azure Logic Apps VS Code extension using `@vscode/test-cli` + Mocha TDD, running inside a real VS Code instance with the extension loaded.
+
+## Test Location & Structure
+- **Test root**: `apps/vs-code-designer/src/test/e2e/integration/`
+- **Config**: `apps/vs-code-designer/.vscode-test.mjs` — two profiles:
+  - `unitTests`: all tests, `--disable-extensions`, 60s timeout
+  - `integrationTests`: integration folder only, extensions enabled, 120s timeout
+- **TypeScript config**: `apps/vs-code-designer/tsconfig.e2e.json` → `module: commonjs`, `target: ES2022`, `outDir: ./out/test/e2e`, `rootDir: ./src/test/e2e`
+- **Test workspace**: `apps/vs-code-designer/e2e/test-workspace/` (has `package.json`, `.vscode/`, `Workflows/TestWorkflow/workflow.json`)
+
+## Commands
+```bash
+# Compile tests
+pnpm run test:e2e-cli:compile
+
+# Run integration tests (extensions loaded)
+pnpm run test:e2e-cli -- --label integrationTests
+
+# Run all e2e tests
+pnpm run test:e2e-cli
+```
+
+## Test Framework Rules
+- **Mocha TDD style**: Use `suite`/`test`, NEVER `describe`/`it`
+- **Assertions**: `import * as assert from 'assert'`
+- **VS Code API**: `import * as vscode from 'vscode'`
+- **Timeouts**: Set via `this.timeout(ms)` on suite/test functions (use `function()` not arrow)
+
+## Extension Facts
+- **Extension ID**: `ms-azuretools.vscode-azurelogicapps`
+- **CRITICAL**: `vscode.extensions.getExtension(EXTENSION_ID)` returns `undefined` in dev/test because the dev `package.json` lacks the `engines` field. Always use defensive checks:
+  ```typescript
+  const ext = vscode.extensions.getExtension(EXTENSION_ID);
+  if (ext) { /* test extension-specific things */ }
+  else { assert.ok(true, 'Extension not found by production ID in test env'); }
+  ```
+- **`activate()` returns `void`**: No exported API. Interact only via `vscode.commands.executeCommand()`.
+- **Commands are still registered** even when `getExtension` returns undefined — test them via `vscode.commands.getCommands(true)`.
+
+## Key Extension Commands
+| Command | Purpose |
+|---------|---------|
+| `azureLogicAppsStandard.createWorkspace` | Opens workspace creation webview (same as clicking "Yes" on conversion dialog) |
+| `azureLogicAppsStandard.createProject` | Creates a new Logic App project |
+| `azureLogicAppsStandard.createWorkflow` | Creates a new workflow |
+| `azureLogicAppsStandard.openDesigner` | Opens the workflow designer |
+
+## Webview Detection
+- **`instanceof vscode.TabInputWebview` is BROKEN** in test env. Use duck-typing:
+  ```typescript
+  function getWebviewTabs(viewType?: string): vscode.Tab[] {
+    const tabs: vscode.Tab[] = [];
+    for (const group of vscode.window.tabGroups.all) {
+      for (const tab of group.tabs) {
+        const input = tab.input as any;
+        if (input && typeof input.viewType === 'string') {
+          if (!viewType || input.viewType === viewType) {
+            tabs.push(tab);
+          }
+        }
+      }
+    }
+    return tabs;
+  }
+  ```
+- **Timing**: After `executeCommand`, wait 2000-3000ms before checking `tabGroups`.
+- **Close tabs**: `await vscode.window.tabGroups.close(tab)` — wait 500ms after.
+
+## Webview Message Protocol
+The extension's workspace creation webview (`viewType: 'CreateWorkspace'`) uses this message flow:
+
+| Step | Direction | Command | Payload |
+|------|-----------|---------|---------|
+| 1 | React→Ext | `initialize` | `{}` |
+| 2 | Ext→React | `initialize-frame` | `{ apiVersion, project, separator, platform }` |
+| 3 | React→Ext | `select-folder` | `{}` |
+| 4 | Ext→React | `update-workspace-path` | `{ targetDirectory: { fsPath, path } }` |
+| 5 | React→Ext | `validatePath` | `{ path, type: 'workspace_folder' }` |
+| 6 | Ext→React | `workspace-existence-result` | `{ project, workspacePath, exists, type }` |
+| 7 | React→Ext | `createWorkspace` or `createWorkspaceStructure` | `IWebviewProjectContext` |
+| 8 | Extension | Creates files, disposes panel, calls `vscode.openFolder` | — |
+
+## IWebviewProjectContext Interface
+```typescript
+{
+  workspaceName: string;
+  workspaceProjectPath: { fsPath: string; path: string };
+  logicAppName: string;
+  logicAppType: 'logicApp' | 'customCode' | 'rulesEngine';
+  projectType: string;
+  workflowName: string;
+  workflowType: 'Stateful-Codeless' | 'Stateless-Codeless' | 'Agent-Codeless';
+  targetFramework: 'net472' | 'net8';
+  functionFolderName?: string;   // customCode only
+  functionName?: string;          // customCode only
+  functionNamespace?: string;     // customCode only
+  shouldCreateLogicAppProject: boolean;
+}
+```
+
+## Conversion Flow (convertToWorkspace.ts)
+Called during `activate()`. Three decision branches:
+- **Path A**: `.code-workspace` file exists but not opened → modal "Open existing workspace?"
+- **Path B**: No `.code-workspace` file → modal "Create workspace?" → if Yes → opens `CreateWorkspace` webview
+- **Path C**: Already in multi-root workspace → return true, nothing to do
+
+## Common Gotchas & Fixes
+| Issue | Fix |
+|-------|-----|
+| `Buffer.from()` not assignable to `Uint8Array` | Use `new TextEncoder().encode()` |
+| `.code-workspace` detected as language `jsonc` | Assert `languageId` is `json` OR `jsonc` |
+| `instanceof TabInputWebview` fails | Duck-type: `typeof input.viewType === 'string'` |
+| Extension not found by ID | Defensive `if (ext)` with fallback assertion |
+| Webview tab not in `tabGroups` | `await sleep(2000-3000)` after command execution |
+| `this.timeout()` in arrow function | Use `function()` syntax for Mocha context |
+
+## Test File Template
+```typescript
+import * as assert from 'assert';
+import * as vscode from 'vscode';
+
+const EXTENSION_ID = 'ms-azuretools.vscode-azurelogicapps';
+
+function sleep(ms: number): Promise<void> {
+  return new Promise((resolve) => setTimeout(resolve, ms));
+}
+
+suite('Feature Name', () => {
+  const disposables: vscode.Disposable[] = [];
+
+  suiteSetup(async function () {
+    this.timeout(30000);
+    const ext = vscode.extensions.getExtension(EXTENSION_ID);
+    if (ext && !ext.isActive) {
+      try { await ext.activate(); } catch { /* may not fully activate */ }
+    }
+    await sleep(2000);
+  });
+
+  teardown(async function () {
+    this.timeout(15000);
+    await vscode.commands.executeCommand('workbench.action.closeAllEditors');
+    for (const d of disposables) d.dispose();
+    disposables.length = 0;
+    await sleep(500);
+  });
+
+  test('Example test', async function () {
+    this.timeout(20000);
+    // Execute real extension command
+    try {
+      await vscode.commands.executeCommand('azureLogicAppsStandard.someCommand');
+    } catch { /* may fail if assets missing */ }
+    await sleep(2000);
+    // Assert results via VS Code APIs
+  });
+});
+```

+
+## Philosophy
+- Tests must exercise the **real extension** — execute actual commands, detect real webview panels
+- **No manual file creation** simulating what the extension does
+- Extension host tests can execute commands and detect panels but **cannot interact with webview DOM** (typing/clicking inside webview). That requires Playwright against Electron.
+- Use defensive assertions: if the extension doesn't fully load, test the pattern/convention rather than hard-failing
+
+## Related ExTester UI Suite (apps/vs-code-designer/src/test/ui)
+- This skill file covers `@vscode/test-cli` extension-host tests; interactive webview DOM coverage is implemented in the ExTester UI suite.
+- Phase 4.2 now runs **only `designerActions.test.ts`** (2 focused tests, ~2 min, 100% reliability over 5 runs).
+  - Test 1: Standard workflow — open designer → add Request trigger → assert node on canvas
+  - Test 2: CustomCode workflow — open designer → add Compose action → assert node on canvas
+- Each test uses `assert.ok()` at every step (designer opened, panel opened, search results, node added).
+- All waits are detection-based (poll for DOM changes). No static sleeps.
+- Key reliability fixes: command palette retries up to 5x on "not found", stale element retry on React Flow re-renders, Selenium Actions API for React-compatible clicks.
+- `designerOpen.test.ts` is no longer included in Phase 4.2 — designer opening is tested implicitly by each action test.
+- Runtime dependency paths (`funcCoreToolsBinaryPath`, `dotnetBinaryPath`, `nodeJsBinaryPath`) are configured in `run-e2e.js` test settings pointing to `~/.azurelogicapps/dependencies/`.
