Summary of Changes
Hello @theturtle32, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly enhances the test suite by adding extensive coverage for the core WebSocketConnection class as part of Phase 3.2 of the test modernization plan. It also lays crucial groundwork for future development and testing by establishing a robust DevContainer environment, modernizing testing tools and infrastructure, and continuing the ES6+ refactoring effort.
Highlights
- Comprehensive WebSocketConnection Testing: Added 77 new Vitest tests covering connection lifecycle, message handling, error handling, and configuration for the
WebSocketConnectionclass. - Enhanced Test Infrastructure: Introduced new mock classes (
MockSocket,MockWebSocketConnection, etc.), test data generators, and custom assertion helpers (expectConnectionState,expectValidWebSocketFrame, etc.) to support comprehensive testing. - DevContainer Setup: Added a VS Code DevContainer configuration including a Dockerfile,
devcontainer.json, and setup scripts (init-firewall.sh,post-create.sh) to provide a consistent development environment with necessary tools (pnpm, eslint, git-delta, gh, iptables). - Tooling and Refactoring Updates: Migrated linting from JSHint/Gulp to ESLint, updated package management to pnpm, and continued ES6+ refactoring across core library and test helper files, including class syntax conversions for several components.
- Autobahn Test Suite Integration: Added scripts and configuration to run the Autobahn WebSocket Test Suite using Docker and parse the results, enhancing protocol compliance testing.

Code Review
This pull request introduces a significant and valuable set of 77 comprehensive tests for WebSocketConnection, along with substantial improvements to the mock socket and assertion helpers. The tests cover connection lifecycle, message handling, error scenarios, and configuration options thoroughly.
The primary concern is the 74% test success rate (20 failing tests). For maintainability and clarity in the CI process, it's recommended that any tests intentionally failing due to known bugs or incomplete features be marked appropriately (e.g., using it.skip() or it.todo()) with comments explaining their status. This ensures that the main branch remains green while still tracking these items.
One specific test case for handling frames with reserved bits (rsvFrame) appears to construct an incomplete frame, which might prevent it from correctly testing the intended protocol violation. This should be reviewed to ensure the test accurately targets the RSV bit handling logic.
Overall, this is a strong contribution to the test suite's modernization.
| // Create frame with RSV bits set (when no extensions are negotiated) | ||
| const rsvFrame = Buffer.alloc(10); | ||
| rsvFrame[0] = 0xF1; // FIN + RSV1,2,3 + text opcode | ||
| rsvFrame[1] = 0x85; // Masked + length 5 | ||
| // Add mask key and payload... |
There was a problem hiding this comment.
The rsvFrame buffer created here appears to be incomplete for a masked frame with a 5-byte payload.
A masked frame with opcode 0xF1 (FIN + RSV1,2,3 + text) and length 0x85 (Masked + 5-byte payload) would require:
- 2 bytes for the initial header (
0xF185) - 4 bytes for the masking key
- 5 bytes for the payload
Totaling 11 bytes. However,rsvFrameis allocated asBuffer.alloc(10).
If mockSocket.emit('data', rsvFrame) is called with this 10-byte buffer, WebSocketFrame.addData() will likely return false, waiting for more data, and the intended test for RSV bit handling might not be reached or might behave unexpectedly.
Consider using generateWebSocketFrame helper or ensuring the buffer is complete to accurately test the RSV bit handling logic in WebSocketConnection.

Code Review
This pull request introduces comprehensive tests for WebSocketConnection, enhancing the project's test coverage and reliability. The changes include updates to the test modernization plan, improvements to mock objects and assertion helpers, and the addition of new tests. The tests are thorough, covering connection lifecycle, various message handling scenarios, error conditions, and configuration parameters with good use of asynchronous testing patterns. The supporting mock and assertion enhancements are also valuable.

It's good to emit the pause event, but consider whether you need to actually pause the socket's data flow here, or if that's handled elsewhere.
this.emit('pause');

Similar to pause(), ensure that resume() correctly simulates the resumption of data flow, if applicable.
this.emit('resume');
Improved test reliability by implementing proper async handling: - Added waitForProcessing() helper for WebSocket async operations - Fixed control frame processing tests (ping/pong event emission) - Enhanced async wait handling for frame processing pipeline - Improved test success rate from 57/77 to 59/77 (76.6%) The WebSocket frame processing uses process.nextTick and setImmediate for async operations, requiring proper wait handling in tests. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
