…testing - DigitalOcean droplet provisioning (create/destroy) - SSH-based command execution on droplets - Parallel execution with progress tracking - Results collection via SFTP - Background execution for long-running tests - Results aggregation across multiple droplets
- Fix latency aggregation bug (allLatencies was never populated) - Rename latency → connectTime to match scaffolding PR - Use corepack for Yarn installation instead of npm install -g yarn - Fix SSH exit code null handling (assume failure if no exit code) - Add concurrency limit (5) for droplet creation to avoid rate limits - Add aggregator input validation for required fields - Extract DROPLET_HOURLY_COST constant
- Add branch name validation to prevent shell injection (droplet.ts, infra.ts) - Add regex escaping for name prefix to prevent incorrect droplet matching - Add shell single-quote escaping for file paths in wait command - Add NaN validation for timeout/interval to prevent infinite loops - Add timeout to SFTP download to prevent hanging indefinitely

Add client.end() calls to error handlers in execSsh and downloadFile functions. Previously, connection errors (e.g., ECONNREFUSED, auth failures) would clear the timeout and reject the promise but not explicitly close the SSH connection, potentially leaking socket resources.

Summary
Adds infrastructure management for distributed load testing using DigitalOcean droplets.
What's included
CLI Commands (
yarn infra)create- Provision DigitalOcean droplets with Node.js, clone repo, install depsdestroy- Tear down all load test dropletslist- Show current droplets and hourly costexec- Run commands on all droplets (with--backgroundfor fire-and-forget)wait- Poll for a file to exist on droplets (for async completion)update- Git pull and rebuild on all dropletscollect- Download result files via SFTPResults Aggregation (
yarn results)aggregate- Combine results from multiple droplets into a single summaryValidated
Successfully ran a 70K connection steady-state test (35k per relay server instance) (10 droplets × 7K connections, 5 min hold):

Note
Adds end-to-end tooling for distributed load testing across DigitalOcean droplets.
