JJ Con 2026 - More props for jj tests - Gašper Štukelj

Proper tests are a must-have for many reasons, but one in particular stands out: they are great vehicles for encoding and sharing knowledge. You can learn a lot about jj just by reading its tests. So let's give props where props are due — by building a proof-of-concept for property-based testing of jj-cli. How could we generate many, many random test environments? What props could we test? This talk covers the setup, how it came about, and most importantly how we can take it further. #tech #opensource #jjvcs #jjcon
