feat: integration tests with worker

[AshishKumar4]

Summary

Adds comprehensive integration tests that can run both directly via Bun and through a Cloudflare Worker, enabling SDK testing in a worker environment.

Changes

• Refactored integration.test.ts to use shared test flow functions from new test-flow.ts
• Added test-flow.ts with reusable test helpers (testAuth, testFullBuild) that work in both Bun and Worker environments
• Added worker.integration.test.ts for running SDK tests through a local Cloudflare Worker
• Added sdk/test/integration/worker/ directory with a minimal Cloudflare Worker that executes SDK tests:
  • index.ts: Worker entry point exposing /test-auth and /test-sdk-build endpoints
  • wrangler.toml: Worker configuration
  • Supporting files (package.json, tsconfig.json, bun.lock)

Motivation

• Validates that the SDK works correctly when running inside a Cloudflare Worker (the primary deployment target)
• Provides reusable test infrastructure that can be shared across different test environments
• Enables step-by-step verification of the build flow with detailed logging

Testing

• Run Bun integration tests: VIBESDK_API_KEY=<key> bun run test:integration
• Run Worker integration tests: Tests spawn a local wrangler dev server automatically
• Both test suites verify: client creation, auth check, token exchange, and full build flow

Code Quality

Critical: None

High: None

Medium:

1. Potential resource leak in test-flow.ts (lines 229-246): The setTimeout(() => clearInterval(interval), 120000) creates a timeout that isn't cleared when the promise resolves early. This is minor since tests terminate anyway, but could be cleaner:

   // Current: timeout not cleared on early resolution
   const interval = setInterval(checkFiles, 500);
   setTimeout(() => clearInterval(interval), 120000);
   
   // Better: track and clear both on resolution

2. Default URL change: The default VIBESDK_BASE_URL changed from http://localhost:5173 to https://build.cloudflare.dev. This may affect developers expecting local testing by default.

Low:

1. The arrow syntax -> in error message (line 14 of integration.test.ts) could use → for consistency with other parts of the codebase (or keep as ASCII for terminal compatibility).

Security

Critical: None

High: None

Medium: None

Low:

1. .dev.vars file is created with API keys during tests - properly cleaned up in afterAll, which is good. Ensure this file is in .gitignore (it likely is already).

Testing

• The PR adds comprehensive integration tests with proper setup/teardown
• Tests handle rate limiting gracefully
• 10-minute timeout for full build tests is appropriate
• Worker tests spin up a local wrangler dev server automatically

---

Final Recommendation

Approve - This is a well-structured PR that adds valuable integration test infrastructure. The code quality is good with proper TypeScript types, error handling, and cleanup. The minor issues noted are non-blocking and don't affect functionality. The ability to test the SDK in a worker environment is valuable for validation.

Positive aspects:

• Clean separation with reusable test-flow.ts helpers
• Proper async/await patterns and error handling
• Good logging for debugging test runs
• Graceful handling of rate limits
• Automatic cleanup of temporary files
