test-gen-service — launch kit

1-liner

Auto-generate pytest / jest tests for an existing codebase. $500-2K per repo, Qwen-powered.

Tweet hook

Every legacy codebase has 0-30% coverage. Backfill via human dev: 2-4 weeks. Backfill via Qwen: 1 day.

Built it. Operator runs against repo, ships baseline tests, iterates.

test-gen-service

Auto-generate idiomatic tests (pytest, jest) for an existing codebase. Sells to teams with low coverage who want a base layer fast. Qwen-powered.

Pricing

• One-shot per repo: $500-2,000
• Subscription: $99-299/mo per repo (regenerate on diff)
• DIY: $0 — operator runs locally

Run

cd C:\openclaw-products\test-gen-service
python -m venv .venv
.\.venv\Scripts\activate
pip install -e .

testgen pytest-for src/utils.py --out tests/test_utils.py
testgen jest-for src/api.ts --out src/api.test.ts

Roadmap

• Repo-wide mode (testgen all-py path/to/repo --out tests/)
• Run-and-iterate (run pytest, feed failures back to Qwen)
• Coverage-gap targeting (only generate for currently uncovered lines)
• Mocking-config heuristic (auto-mock heavy deps)
