Touca – a better alternative to snapshot testing
Hi everyone, Almost 2 years ago, I left my full-time job at Canon to build tooling and infrastructure to help developers write high-level tests for complex software workflows that are not easy to unit test. I wanted to take ideas from visual regression testing, snapshot testing, and property-based testing and build a general-purpose regression testing system that developers can use to find the unintended side-effects of their day-to-day code changes during the development stage. After two years of working ~70 hours per week and going through multiple iterations, we finally have a fully…

In plain words
Touca is an open-source regression testing system designed for developers testing complex software workflows that are difficult to unit test. It combines concepts from visual regression testing, snapshot testing, and property-based testing to help developers detect unintended side effects during development. The tool is self-hostable and works for both small and large teams.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
