How can you use code coverage and mutation testing to add tests to legacy code? At @mendercon last year, I demonstrated this powerful technique step by step on the Gilded Rose kata, which is hosted by @emilybache on her GitHub account: https://github.com/emilybache/GildedRose-Refactoring-Kata

I’ve been a big fan of #MutationTesting since I discovered PIT. As I dive deeper into #Rust, I wanted to check the state of mutation testing in Rust.

Mutation Testing in Rust

I’ve been a big fan of Mutation Testing since I discovered PIT. As I dive deeper into Rust, I wanted to check the state of mutation testing in Rust. Starting with cargo-mutants I found two crates for mutation testing in Rust: cargo-mutantsand mutagen mutagen hasn’t been maintained for three years, while cargo-mutants is still under active development. I’ve ported the sample code from my previous Java code to Rust: struct LowPassPredicate { threshold: i32, } impl
