You can now test file uploads on Test-Lab. Reference {{file.pdf}} in any test plan and a real, valid file is uploaded through the picker: PDFs, images, audio, video, and archives in every size, with no fixtures to install or commit.
Playwright MCP drives a browser. Test-Lab's MCP manages and runs tests. Here is how the two MCP servers differ, when to use each, and why they work well together.
Test-Lab.ai ships its own MCP server so AI agents can create, run, and manage real browser tests. Here is what it does, the tools it exposes, and how it differs from Playwright MCP.
Anthropic just shipped Claude Fable 5, its first public Mythos-class model. We break down the benchmarks and pricing against Opus 4.8, GPT-5.5, and Gemini 3.1 Pro, the silent fallback nobody is talking about, and what it means for coding agents and AI browser testing.
Playwright MCP lets AI agents drive a real browser through structured accessibility snapshots, no screenshots or scripts. Here is what it is, the tools it exposes, and when to use it.
Point Claude Code, Codex, or Cursor at your app. It writes test-lab plans grounded in your code, or converts the tests you already have, then ships them in one command.
Click into the real test-lab.ai admin without an account. Browse example test plans, open real run reports, and see the CI setup we run on every deploy, most of it cheap Playwright script runs.
Test-Lab's AI Playwright script generation is leaving beta. After thousands of real test plans, a pipeline of specialized agents over multiple models lifted clean-script success by 30 to 40 percent. Here is what changed and what you get today.
Define test personas, emails, and IDs once and reference them across every plan with {{data.X}}. Static for stability, Dynamic for per-run uniqueness, pipeline-shared values for multi-step flows, frozen snapshots in every run report.
Set up per-project test environments and run the same test plans against prod, staging, uat, and PR previews with no plan edits. Each env carries its own URL, notifications, cookies, and proxy country.
