Show HN: Merunit – Visual-first unit test generator (waitlist)

https://merunit.io
1•laguerdo•1d ago
Hi HN,

I’ve been frustrated with how repetitive and tedious writing unit tests can be, especially when you’re just trying to ship fast.

So I’m building Merunit, a visual-first unit test generator that helps you create and export tests without boilerplate or syntax. You define test cases with inputs/outputs, and it generates framework-ready test code.

It runs locally in the browser, no uploads or sync.

The MVP is focused on devs who are tired (or afraid) of repeating logic just to test it.

Would love feedback or ideas from the community.

Join the waitlist here: https://merunit.io
