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 represents Phase 1 of the test suite modernization effort. My goal was to establish the foundational infrastructure using the Vitest framework. This includes setting up the test runner, defining shared utilities for configuration and environment management, and adding a basic test to confirm the setup is functional. This PR doesn't migrate existing tests but provides the necessary tooling and structure for subsequent phases.

Highlights

Introduce Vitest: I've set up Vitest as the new test runner for the project, laying the groundwork for modernizing the test suite.
Shared Test Utilities: I've added shared configuration constants (test/shared/config.js) and global setup/teardown files (test/shared/setup.js, test/shared/teardown.js) to provide a consistent environment for future tests.
Initial Smoke Test: A basic smoke test (test/smoke.test.js) has been added to validate that the Vitest setup is working correctly, can access shared configurations, handle async operations, and work with Buffers.
Dependency and Script Updates: I've added Vitest and related dependencies (@vitest/coverage-v8, @vitest/ui) to package.json and introduced new test scripts (test:vitest, test:watch, test:ui, test:coverage, test:coverage:watch).
Coverage Configuration: I've configured Vitest to generate code coverage reports using the v8 provider, excluding specific directories and setting global threshold targets.

Code Review

This pull request successfully establishes a foundational infrastructure for modernizing the test suite with Vitest. The introduction of shared test configurations, setup/teardown utilities, and an initial smoke test are positive steps. The package.json updates and .gitignore changes are appropriate for integrating Vitest.

Key areas for consideration and clarification include:

Node.js Version Compatibility: There's a potential conflict between Vitest's Node.js version requirements (14.18+) and the project's stated support for Node.js 4.x+. Clarification on how testing will cover older Node.js versions is needed.
Logging in Test Utilities: The use of console.log in test/shared/setup.js and test/shared/teardown.js could be aligned with the project's guideline of using the debug module for such logging.

Overall, this is a good advancement for the project's testing capabilities. Addressing the points above will help ensure robustness and consistency.

The project's package.json (line 27) and coding guidelines (CLAUDE.md¹) state support for Node.js 4.x+. However, Vitest, introduced here, requires Node.js 14.18+ (or 16+). This creates a situation where the new test suite cannot run on the full range of Node.js versions the library aims to support.

Please clarify the testing strategy for older Node.js versions (e.g., Node 4.x up to Node 14.x). For example:

Will the existing tape tests (still available via npm test) be the primary means of ensuring compatibility on these older versions?

Is there a plan to run different test suites based on the Node.js environment?

Addressing this is important for maintaining the stated backward compatibility. The PR description also includes the checklist item "[x] Vitest configuration works with existing Node.js compatibility requirements", which appears to conflict with Vitest's minimum Node.js version. An explanation here would be helpful.

test/shared/setup.js

+// Global setup function
+export function setup() {
+  // Global test setup logic can be added here
+  console.log('Setting up WebSocket-Node test environment...');


Consider using the debug module for this informational log, as recommended by the project's coding style guide for debug logging¹. This would involve importing debug (e.g., import debug from 'debug';), creating a logger instance (e.g., const log = debug('websocket:test:setup');), and then using log().

This approach provides more control over log output (e.g., enabling/disabling via DEBUG environment variable) and aligns with established practices within the project.

test/shared/teardown.js

+// Global teardown function
+export function teardown() {
+  // Global test cleanup logic can be added here
+  console.log('Tearing down WebSocket-Node test environment...');


Similar to the setup script, consider using the debug module here instead of console.log, in line with the project's coding style guide for debug logging¹. You would import debug, create a specific logger instance (e.g., const log = debug('websocket:test:teardown');), and then use log().

This promotes consistency and better log management.
