+# E2E Testing Guide
+
+## Build/Lint/Test Commands
+
+```bash
+# Run all e2e tests
+bun test:e2e
+
+# Run specific test file
+bun test:e2e -- app/home.spec.ts
+
+# Run single test by title
+bun test:e2e -- -g "home renders and shows core entrypoints"
+
+# Run tests with UI mode (for debugging)
+bun test:e2e:ui
+
+# Run tests locally with full server setup
+bun test:e2e:local
+
+# View test report
+bun test:e2e:report
+
+# Typecheck
+bun typecheck
+```
+
+## Test Structure
+
+All tests live in `packages/app/e2e/`:
+
+```
+e2e/
+├── fixtures.ts       # Test fixtures (test, expect, gotoSession, sdk)
+├── actions.ts        # Reusable action helpers
+├── selectors.ts      # DOM selectors
+├── utils.ts          # Utilities (serverUrl, modKey, path helpers)
+└── [feature]/
+    └── *.spec.ts     # Test files
+```
+
+## Test Patterns
+
+### Basic Test Structure
+
+```typescript
+import { test, expect } from "../fixtures"
+import { promptSelector } from "../selectors"
+import { withSession } from "../actions"
+
+test("test description", async ({ page, sdk, gotoSession }) => {
+  await gotoSession() // or gotoSession(sessionID)
+
+  // Your test code
+  await expect(page.locator(promptSelector)).toBeVisible()
+})
+```
+
+### Using Fixtures
+
+- `page` - Playwright page
+- `sdk` - OpenCode SDK client for API calls
+- `gotoSession(sessionID?)` - Navigate to session
+
+### Helper Functions
+
+**Actions** (`actions.ts`):
+
+- `openPalette(page)` - Open command palette
+- `openSettings(page)` - Open settings dialog
+- `closeDialog(page, dialog)` - Close any dialog
+- `openSidebar(page)` / `closeSidebar(page)` - Toggle sidebar
+- `withSession(sdk, title, callback)` - Create temp session
+- `clickListItem(container, filter)` - Click list item by key/text
+
+**Selectors** (`selectors.ts`):
+
+- `promptSelector` - Prompt input
+- `terminalSelector` - Terminal panel
+- `sessionItemSelector(id)` - Session in sidebar
+- `listItemSelector` - Generic list items
+
+**Utils** (`utils.ts`):
+
+- `modKey` - Meta (Mac) or Control (Linux/Win)
+- `serverUrl` - Backend server URL
+- `sessionPath(dir, id?)` - Build session URL
+
+## Code Style Guidelines
+
+### Imports
+
+Always import from `../fixtures`, not `@playwright/test`:
+
+```typescript
+// ✅ Good
+import { test, expect } from "../fixtures"
+
+// ❌ Bad
+import { test, expect } from "@playwright/test"
+```
+
+### Naming Conventions
+
+- Test files: `feature-name.spec.ts`
+- Test names: lowercase, descriptive: `"sidebar can be toggled"`
+- Variables: camelCase
+- Constants: SCREAMING_SNAKE_CASE
+
+### Error Handling
+
+Tests should clean up after themselves:
+
+```typescript
+test("test with cleanup", async ({ page, sdk, gotoSession }) => {
+  await withSession(sdk, "test session", async (session) => {
+    await gotoSession(session.id)
+    // Test code...
+  }) // Auto-deletes session
+})
+```
+
+### Timeouts
+
+Default: 60s per test, 10s per assertion. Override when needed:
+
+```typescript
+test.setTimeout(120_000) // For long LLM operations
+test("slow test", async () => {
+  await expect.poll(() => check(), { timeout: 90_000 }).toBe(true)
+})
+```
+
+### Selectors
+
+Use `data-component`, `data-action`, or semantic roles:
+
+```typescript
+// ✅ Good
+await page.locator('[data-component="prompt-input"]').click()
+await page.getByRole("button", { name: "Open settings" }).click()
+
+// ❌ Bad
+await page.locator(".css-class-name").click()
+await page.locator("#id-name").click()
+```
+
+### Keyboard Shortcuts
+
+Use `modKey` for cross-platform compatibility:
+
+```typescript
+import { modKey } from "../utils"
+
+await page.keyboard.press(`${modKey}+B`) // Toggle sidebar
+await page.keyboard.press(`${modKey}+Comma`) // Open settings
+```
+
+## Writing New Tests
+
+1. Choose appropriate folder or create new one
+2. Import from `../fixtures`
+3. Use helper functions from `../actions` and `../selectors`
+4. Clean up any created resources
+5. Use specific selectors (avoid CSS classes)
+6. Test one feature per test file
+
+## Local Development
+
+For UI debugging, use:
+
+```bash
+bun test:e2e:ui
+```
+
+This opens Playwright's interactive UI for step-through debugging.
