KeelTest

AI-powered unit test generator for Python that actually works.

What is KeelTest?

KeelTest generates production-ready pytest unit tests using AI. It analyzes your project, generates tests, runs them locally, and fixes failures automatically before showing you results.

The difference: 70%+ pass rate guarantee or refund.

Why not GitHub Copilot or Cursor?

Tools like Copilot, Cursor, and ChatGPT are great at generating code that looks right. But when you run AI-generated tests, they often fail with import errors, incorrect mocks, or hallucinated fixtures.

KeelTest solves this:

Tests are actually run in your environment before delivery
Failures trigger automatic fixes (reads pytest output, adjusts code, retries)
Project-wide analysis prevents import and dependency errors
You only pay for tests that pass

Stop copy-pasting test suggestions and debugging them manually. Get verified, working tests from the start.

Features

Tests validated and run locally before delivery
Self-healing: auto-fixes failing tests through iteration
Per-function generation for maintainable tests
Library-specific strategies (FastAPI, Pydantic, SQLAlchemy, pandas, etc.)
Ruff integration for code quality
Works with Poetry or pip
