This PR addresses two critical issues preventing proper functionality of the CodeceptJS UI:

Issue 1: File Content Loading Fails with 400 Error

When clicking on a test file to view its content, the frontend was receiving a 400 Bad Request error:

POST http://localhost:3333/api/file 400 (Bad Request)

Root Cause: The frontend sends a POST request with JSON body { path: test.file, line: test.line }, but the backend API expected the file path in req.file parameter instead of req.body.path.

Solution:

  • Modified /api/file endpoint to read from req.body.path for new frontend requests
  • Added JSON body parser middleware to handle POST requests properly
  • Maintained backward compatibility by still supporting legacy req.file parameter
  • Returns JSON response with source field for frontend consumption while preserving file streaming for legacy usage

Issue 2: WebSocket Connection Refused Error

Browser tests couldn't start due to WebSocket connection failures:

GET http://localhost:2999/socket.io/?EIO=3&transport=polling&t=Pa50TTj net::ERR_CONNECTION_REFUSED

Root Cause: The frontend was constructing WebSocket URLs using window.location.protocol (e.g., http:), but WebSocket connections require ws: or wss: protocols.

Solution:

  • Fixed WebSocket URL construction in src/main.js to properly convert http:ws: and https:wss:
  • Ensures WebSocket connections use the correct protocol regardless of the page's protocol

Key Changes

  1. lib/api/get-file.js: Enhanced to support both JSON body requests and legacy parameter requests
  2. lib/api/index.js: Added JSON body parser to /api/file endpoint
  3. src/main.js: Fixed WebSocket URL protocol conversion

Testing

  • All existing tests pass (143 tests passed, 1 skipped)
  • Backward compatibility maintained for existing API usage
  • Build completes successfully with no breaking changes

These changes ensure that both test file content loading and WebSocket-based browser test execution work correctly.

Fixes #570.
