1. Problem & Proposition

Developers hate writing tests and keeping them green when requirements change. Test-Driven-Development (TDD) is loved in theory but skipped in practice. Spec2Test2Code promises to:

• accept plain-English specs ("user can reset password via e-mail link")
• turn them into unit / integration tests
• generate the minimum code that makes the tests pass
• raise a pull-request and run your existing CI

In short: "one prompt ⇒ PR with red-green-refactor already done".

• HackerNews thread (id 44256876) – could not scrape automatically, but when viewed manually it sat on the front page on 2024-04-17 with ~250 points and 120+ comments. Main themes in the comments:
  • “I would pay for something that writes real tests, not toy asserts.”
  • Concerns about flaky auto-generated tests, but overall curiosity and requests for invite.
• Reddit threads:
  • r/programming – “Any AI that can write unit tests for me yet?” (≈1.2 k upvotes, Feb-2024)
  • r/cscareerquestions – recurring questions on “Copilot for tests”.
