Frequently asked questions
How many open source testing-tools projects are there?
This registry tracks 10 projects tagged testing-tools, with 80,030 GitHub stars between them. The most-adopted is mocha at 22,912 stars.
Are these testing-tools projects free to use?
Yes — 10 of the 10 carry an explicit open-source licence across 3 distinct licences, so there is no licence fee. Where a project also sells a hosted or enterprise version, the self-hosted path remains free.
Which testing-tools project should I choose?
The list above is ranked by GitHub stars, but stars measure attention rather than fit. Check three things on each card: the licence (permissive versus copyleft), the language it is written in, and the last-push date — a high-star project that has not been pushed in a year is a liability.
Are these testing-tools projects still maintained?
9 of the 10 were pushed in the last 90 days, and every card shows its exact last-push date so you can see the rest. Sort your shortlist by that date before committing to a migration.
