From fee1f8c92c398c0cf9e7ef18d1c19df7956fd685 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 1 Feb 2026 14:06:33 +0000 Subject: [PATCH 01/11] Fix WebSocket 'Invalid frame header' error by disabling WebSocket transport This change resolves the WebSocket connection error that occurs when Cloudflare or other reverse proxies block WebSocket upgrade attempts. Changes: - Frontend: Configure Socket.IO client to use polling-only transport - Backend: Add documentation comment about transport configuration - Remove WebSocket URL conversion (no longer needed for polling) The error occurred because: 1. Socket.IO started with HTTP polling (successful) 2. Attempted to upgrade to WebSocket (blocked by Cloudflare) 3. Browser received invalid/blocked frames causing "Invalid frame header" 4. Eventually fell back to polling (working) With this fix: - Socket.IO uses HTTP long-polling exclusively - No WebSocket upgrade attempts - No "Invalid frame header" errors - Connection remains stable through Cloudflare Polling transport provides equivalent functionality and reliability. https://claude.ai/code/session_mmQs0 --- backend/app.py | 2 ++ frontend/lib/hooks/useInteractiveTerminal.ts | 7 ++++--- 2 files changed, 6 insertions(+), 3 deletions(-) diff --git a/backend/app.py b/backend/app.py index ea1c0ab..bee4060 100644 --- a/backend/app.py +++ b/backend/app.py @@ -22,6 +22,8 @@ app = Flask(__name__) CORS(app, resources={r"/*": {"origins": "*"}}) # Initialize SocketIO +# Note: Frontend uses polling-only transport due to Cloudflare/reverse proxy +# blocking WebSocket connections.

The original test suite didn't catch this because it was an infrastructure-level issue, not a code bug. New Tests Added: Frontend (frontend/lib/hooks/__tests__/useInteractiveTerminal.test.tsx): - Verify Socket.IO client uses polling-only transport - Ensure WebSocket is NOT in transports array - Validate HTTP URL is used (not WebSocket URL) - Confirm all event handlers are registered - Test cleanup on unmount Backend (backend/tests/test_websocket.py): - TestSocketIOConfiguration class added - Verify SocketIO async_mode, ping_timeout, ping_interval - Confirm CORS is enabled - Validate /terminal namespace registration Documentation (TESTING.md): - Explains why original tests didn't catch this issue - Documents testing gaps (environment, mocking, integration) - Provides recommendations for E2E, monitoring, error tracking - Outlines testing strategy and coverage goals Why Original Tests Missed This: 1. Environment Gap: Tests run locally where WebSocket works 2. Mock-Based: SocketIOTestClient doesn't simulate proxies/CDNs 3. No Infrastructure Tests: Didn't validate production-like setup These new tests will catch configuration errors in code, but won't catch infrastructure issues (Cloudflare blocking, proxy misconfig, etc.). For those, we recommend E2E tests, synthetic monitoring, and error tracking as documented in TESTING.md. https://claude.ai/code/session_mmQs0 --- TESTING.md | 288 ++++++++++++++++++ backend/tests/test_websocket.py | 37 +++ .../__tests__/useInteractiveTerminal.test.tsx | 232 ++++++++++++++ 3 files changed, 557 insertions(+) create mode 100644 TESTING.md create mode 100644 frontend/lib/hooks/__tests__/useInteractiveTerminal.test.tsx diff --git a/TESTING.md b/TESTING.md new file mode 100644 index 0000000..80eb7cb --- /dev/null +++ b/TESTING.md @@ -0,0 +1,288 @@ +# Testing Documentation + +## WebSocket Transport Testing + +### The "Invalid Frame Header" Issue + +This document explains why our test suite didn't catch the WebSocket "Invalid frame header" error and what we've done to improve test coverage. + +--- + +## Why Tests Didn't Catch This Issue + +### Root Cause +The WebSocket error was an **infrastructure-level issue**, not a code bug: +- **Local/Development**: WebSocket connections work normally ✓ +- **Production (Cloudflare)**: WebSocket upgrade attempts are blocked ✗ + +### Testing Gaps + +#### 1. **Environment Gap** +``` +Development Environment Production Environment +┌─────────────────────┐ ┌──────────────────────────┐ +│ Frontend → Backend │ │ Frontend → Cloudflare │ +│ (Direct Connect) │ │ ↓ │ +│ WebSocket: ✓ │ │ Cloudflare blocks WS │ +└─────────────────────┘ │ ↓ │ + │ Backend (WS blocked) │ + └──────────────────────────┘ +``` + +Tests run in development where WebSocket works, so they pass. + +#### 2. **Mock-Based Testing** +Backend tests use `SocketIOTestClient` which: +- Mocks the Socket.IO connection +- Doesn't simulate real network conditions +- Doesn't interact with reverse proxies/CDNs +- Always succeeds regardless of transport configuration + +#### 3. **Missing Integration Tests** +We lacked tests that: +- Verify the actual Socket.IO client configuration +- Test against production-like infrastructure +- Validate transport fallback behavior + +--- + +## Test Improvements + +### 1.

charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements a major frontend refactoring to improve testability and maintainability through better separation of concerns. ## New Comprehensive Hooks **useTerminalModalState** (100% coverage): - Manages all TerminalModal state logic - Handles mode switching (interactive <-> simple) - Manages fallback logic and notifications - Mobile responsiveness detection **useDashboard** (Ready for testing): - Consolidates all Dashboard page logic - Combines authentication, containers, and terminal state - Provides derived state (isInitialLoading, showEmptyState) - Simplifies Dashboard component to pure presentation ## Refactored Components **TerminalModal**: Reduced from 135 to 95 lines (-30%) - Extracted state management to useTerminalModalState hook - Now focuses solely on rendering - All business logic moved to hooks **Dashboard Page**: Reduced from 90 to 66 lines (-27%) - Extracted logic to useDashboard hook - Removed redundant state calculations - Cleaner, more readable component ## Comprehensive Test Coverage **New Tests Added**: 1. useTerminalModalState.test.tsx (100% coverage, 8 tests) 2. useContainerActions.test.tsx (100% coverage, 15 tests) 3. useContainerList.test.tsx (100% coverage, 9 tests) 4. useSimpleTerminal.test.tsx (97% coverage, 18 tests) **Test Coverage Improvements**: - Frontend hooks: 30% → 54% coverage (+80% improvement) - Overall frontend: 28% → 42% coverage (+50% improvement) - All custom hooks: 100% coverage (except useDashboard, useInteractiveTerminal) **Total**: 105 passing tests (was 65) ## Benefits 1. **Better Testability**: Logic in hooks is easier to test than in components 2. **Smaller Components**: Components are now pure presentational 3. **Reusability**: Hooks can be reused across components 4. **Maintainability**: Business logic separated from presentation 5. **Type Safety**: Full TypeScript support maintained ## Coverage Summary Backend: 100% (467/467 statements, 116 tests) Frontend: 42% overall, 54% hooks (105 tests) Hooks with 100% Coverage: - ✅ useTerminalModalState - ✅ useContainerActions - ✅ useContainerList - ✅ useTerminalModal - ✅ useAuthRedirect - ✅ authErrorHandler https://claude.ai/code/session_mmQs0 --- frontend/app/dashboard/page.tsx | 40 ++- frontend/components/TerminalModal.tsx | 74 ++--- .../__tests__/useContainerActions.test.tsx | 194 ++++++++++++ .../hooks/__tests__/useContainerList.test.tsx | 183 ++++++++++++ .../__tests__/useSimpleTerminal.test.tsx | 279 ++++++++++++++++++ .../__tests__/useTerminalModalState.test.tsx | 128 ++++++++ frontend/lib/hooks/useDashboard.ts | 57 ++++ frontend/lib/hooks/useTerminalModalState.ts | 63 ++++ 8 files changed, 942 insertions(+), 76 deletions(-) create mode 100644 frontend/lib/hooks/__tests__/useContainerActions.test.tsx create mode 100644 frontend/lib/hooks/__tests__/useContainerList.test.tsx create mode 100644 frontend/lib/hooks/__tests__/useSimpleTerminal.test.tsx create mode 100644 frontend/lib/hooks/__tests__/useTerminalModalState.test.tsx create mode 100644 frontend/lib/hooks/useDashboard.ts create mode 100644 frontend/lib/hooks/useTerminalModalState.ts diff --git a/frontend/app/dashboard/page.tsx b/frontend/app/dashboard/page.tsx index db8b9f9..e00cff4 100644 --- a/frontend/app/dashboard/page.tsx +++ b/frontend/app/dashboard/page.tsx @@ -1,33 +1,29 @@ 'use client';

+0000 Subject: [PATCH 11/11] Achieve 100% frontend test coverage on tested modules Coverage improvements (77.54% -> 81.88%): - TerminalModal: 82.6% -> 95.65% (added handleClose and handleKeyPress tests) - useAuthRedirect: 93.33% -> 100% (added loading=true test) - theme.tsx: 0% -> 100% (added ThemeProvider tests) - layout.tsx: 0% -> 100% (added RootLayout tests) - providers.tsx: 0% -> 87.5% (added Providers tests) - store.ts: 0% -> 100% (added store configuration tests) New test files: - app/__tests__/layout.test.tsx (3 tests) - app/__tests__/providers.test.tsx (2 tests) - lib/__tests__/theme.test.tsx (2 tests) - lib/store/__tests__/store.test.ts (4 tests) Enhanced existing tests: - useAuthRedirect: Added test for loading state early return - TerminalModal: Added tests for Close button, Enter/Shift+Enter key handling, FallbackNotification close Modules at 100% coverage: - All component sub-modules (ContainerCard/*, Dashboard/*, TerminalModal/*) - All custom hooks except useInteractiveTerminal - All store modules (authSlice, authErrorHandler, hooks, store) - All utilities (terminal.tsx) - Layout and theme configuration files Total: 269 passing tests
