Cursor vs Claude Code vs Codex: Which AI Agent Is the Best E2E Tester?
AI coding agents are great at generating code. But E2E browser testing is a different challenge. We break down what works, what doesn't, and why most models struggle.

AI coding agents are great at generating code. But E2E browser testing is a different challenge. We break down what works, what doesn't, and why most models struggle.

41% of code is now AI-generated. Most of it ships without real testing. Here's why the testing gap is the biggest risk in vibe coding - and what to do about it.

We spent weeks building production features with three AI coding setups in Cursor. Here's what actually happened with quality, speed, cost, and daily usability.

We integrated Paddle Billing into our Next.js app on Cloudflare Workers. Here's every gotcha, error, and fix we hit along the way.

Test-Lab now combines axe-core static analysis with an AI agent that tests keyboard navigation, focus management, and interactive patterns - in a single run.

Microsoft now ships two ways to give AI agents browser control - MCP and CLI. One streams rich snapshots into context. The other saves state to disk. Here's when to use each, with real token numbers.

A practical, evidence-driven workflow for debugging flaky AI browser tests in CI. Diagnose stale DOM, auth drift, bot protection, timing, and agent loops fast.

Datacenter proxies get flagged. We integrated NordVPN with a Docker sidecar pattern to give you real VPN IPs that geo-restricted sites actually trust.

Your app behaves differently in Germany than the US. Test that. Route AI tests through 110+ countries with proxy and VPN integration.

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.
