Mobile Testing with Browser Emulation: Beyond Desktop
Test-Lab now supports mobile device emulation. Learn how Playwright device mapping works, what gets emulated, and the gotchas to watch out for.

A deep dive into custom header injection - context-level vs request-level approaches, Playwright MCP configuration, and when to use each pattern.

Why general-purpose AI agents fail at browser testing, what it takes to make them reliable, and how Test-Lab handles the hard parts.

Relying on one AI provider is a single point of failure. Here's how we built resilience into Test-Lab with OpenRouter and multi-provider fallbacks.

We started with Goose, Block's open-source AI coding agent. Then we built something custom. Here's what drove that decision and what we learned along the way.

Skip the login dance. Inject session cookies at project, test plan, or runtime level to test authenticated areas without teaching AI to log in.

Set up automated test schedules with cron expressions. Run nightly regressions, hourly health checks, or custom intervals - AI testing on autopilot.

AI testing meets CI/CD. Add intelligent test automation to GitHub Actions or GitLab CI in 5 minutes - no scripts to maintain.
