Copilot · 2025-11-04T16:46:37Z

Plan: Add Tests and CI Integration

Summary

Successfully expanded test coverage from 74 to 170 tests total (13 server + 157 client), achieving comprehensive coverage of core utilities, protocol handling, retry mechanisms, UI theming, and WebRTC connection workflows. All documentation updated to reflect testing infrastructure and semantic commit practices.

Test Coverage Includes:

Server (13 tests)

ID generation and validation
Character exclusion logic

Client (157 tests)

FileChunkManager (28 tests): file slicing, chunk management, merging, validation
msgType utilities (33 tests): link detection, file type identification
FileProtocol (24 tests): message parsing, encoding/decoding, round-trip validation
RetryManager (28 tests): timeout handling, retry logic, state management
ThemeManager (17 tests): theme application, color validation, accessibility
WebRTC Connection Workflow (27 tests): connection initialization, offer/answer exchange, ICE candidate handling, data channel management, connection lifecycle

All tests passing ✅ Builds successful ✅ Documentation updated ✅ CI workflow optimized ✅

Original prompt

Write tests for the project.

Then integrate them into GitHub Actions for automated checks.

Finally, upgrade to a bug fix version.

✨ Let Copilot coding agent set things up for you — coding agent works faster and does higher quality work when set up for your repo.

@copilot I hope to expand the test coverage to include more functions, making it more comprehensive and achieving a higher coverage rate.

Added comprehensive tests for: - FileProtocol (24 tests): message parsing, encoding/decoding, round-trip validation - RetryManager (28 tests): timeout handling, retry logic, state management - ThemeManager (17 tests): theme application, color validation, accessibility Total test count increased from 61 to 130 client tests. Test coverage now includes protocol handling, retry mechanisms, and UI theming. Co-authored-by: WCY-dt <55525165+WCY-dt@users.noreply.github.com>

- Document all 143 tests added (13 server + 130 client) - Break down test coverage by module - Highlight improved ID generation algorithm Co-authored-by: WCY-dt <55525165+WCY-dt@users.noreply.github.com>

@copilot I hope to expand the test coverage to include more functions, making it more comprehensive and achieving a higher coverage rate.

I've expanded test coverage significantly! Added 69 new tests covering:

FileProtocol (24 tests) - Message parsing, encoding/decoding, and round-trip validation for the file transfer protocol

RetryManager (28 tests) - Timeout handling, retry logic, state management, and integration scenarios

ThemeManager (17 tests) - Theme application, color validation, and accessibility checks

Total test count increased from 74 to 143 tests (13 server + 130 client), providing comprehensive coverage of core utilities including protocol handling, retry mechanisms, and UI theming.

All tests passing ✅ (commit: eca9475)

@copilot Can we write tests for the core workflow of using WebRTC for connection and data transmission?

Copilot · 2025-11-04T17:25:30Z

@copilot Can we write tests for the core workflow of using WebRTC for connection and data transmission?

Testing the full WebRTC workflow presents some challenges since it requires mocking RTCPeerConnection, Socket.io, and browser-specific APIs. The stores also have tight coupling with Vue/Pinia and involve complex async state management.

I can create tests that verify:

Key WebRTC logic flows (offer/answer creation, ICE candidate handling)
Data channel state management
Connection lifecycle (connecting → connected → disconnected)

However, these would be unit tests with mocked WebRTC APIs rather than full end-to-end integration tests. For true end-to-end testing of WebRTC connections, you'd typically need a browser automation tool like Playwright or Puppeteer with two browser instances.

Would you like me to proceed with mocked unit tests for the WebRTC workflow, or would you prefer a different testing approach?

WCY-dt · 2025-11-04T17:27:41Z

@copilot The authority to make the decision is yours; use your discretion to select the more appropriate solution.

Added comprehensive tests for WebRTC functionality: - Connection initialization and peer setup - Client registration and ID management - Offer/answer SDP exchange - ICE candidate handling and queuing - Data channel state management and lifecycle - Connection state transitions - Error handling for unexpected scenarios Tests use proper mocks for RTCPeerConnection, Socket.io, and browser APIs. Total test count increased from 130 to 157 client tests (170 total with server). Co-authored-by: WCY-dt <55525165+WCY-dt@users.noreply.github.com>

Copilot · 2025-11-04T17:37:05Z

@copilot The authority to make the decision is yours; use your discretion to select the more appropriate solution.

I've added 27 comprehensive tests for the WebRTC connection workflow covering:

Connection Initialization

Peer connection setup with ICE servers
Socket.io connection establishment
Data channel creation

Signaling Protocol

Client registration and ID management
Offer/answer SDP exchange
ICE candidate handling and queuing

Data Channel Management

Channel state tracking (open/pending)
Connection lifecycle events
Error and close handling

Edge Cases

Unexpected peer IDs
ICE candidates before remote description
Disconnect scenarios

The tests use proper mocks for RTCPeerConnection, Socket.io, and browser APIs, ensuring reliable unit testing without requiring actual network connections.

Total test count: 170 tests (13 server + 157 client) ✅ (commit: c5c3643)

Changed from 'latest' (v25) to Node.js 22 (LTS) in GitHub Actions workflow. This prevents engine compatibility warnings from @achrinza/node-ipc dependency which only supports up to Node.js 22. All tests continue to pass with Node.js 22. Co-authored-by: WCY-dt <55525165+WCY-dt@users.noreply.github.com>

@copilot fix failed workflow:

...

Fixed the workflow by pinning Node.js to version 22 (LTS) instead of "latest" (v25).

The engine warning was from @achrinza/node-ipc which only supports Node.js up to v22. The workflow was actually passing - the error messages shown in the log (like "Failed to parse retry data") are expected console.error outputs from tests that verify error handling.

Changes:

Updated .github/workflows/check.yml to use node-version: '22'
This eliminates the EBADENGINE warning
All 170 tests continue to pass

The workflow will now run cleanly without engine compatibility warnings (commit: ca3e316)
