Instead of fighting agents to write tests, what if the testing agent is the product itself? That's the idea behind Autonoma (https://github.com/autonoma-ai/autonoma), AI agents that do E2E testing by exploring your app like a real user.

I have TDD flow working as a part of my tasks structuring and then task completion. There are separate tasks for making the tests and for implementing. The agent which implements is told to pick up only the first available task, which will be “write tests task”, it reliably does so. I just needed to add how it should mark tests as skipped because it’s been conflicting with quality gates.
