Notes on autonomous test generation, the 5-signal quality verdict, and what we learn building TFactory.

• May 31, 2026 Your test suite is green. It's also lying to you. A test that runs but never fails isn't a test — it's a decoration. Here's how mutation testing catches the fakes.
• May 31, 2026 One spec, five lanes, three languages Most test generators speak one language. Real features don't. Here's how TFactory fans a single handoff across pytest, Jest, and Playwright.
• May 31, 2026 How do you let an AI touch your cloud without handing it the keys? Real integration tests need real credentials. Real credentials must never touch the repo. The Credential Broker squares that circle.
• May 31, 2026 Run the whole thing on your own GPU (yes, with the Wi-Fi off) If your code can't leave the building, your test generator shouldn't phone home either. TFactory runs fully on local models.
• May 31, 2026 Introducing TFactory: test quality, not test count Why we grade generated tests on five signals instead of dumping fifty and calling it coverage.
