The newest feature I've added to the upcoming Pest Mutation Testing plugin, is already one of my favourites: "--retry" 😍
It runs the mutations previously survived first, to have a really fast feedback loop. 🚀
It behaves like `--retry` in Pest.

📣 New Podcast! "343 - Mutation Testing: chi testa i test?" on @Spreaker #dotnet #mutationtesting #strykerdotnet #unittesting
343 - Mutation Testing: chi testa i test?
In questa puntata parlo di Mutation Testing: una tecnica che ci aiuta a capire se i nostri test automatici stanno davvero proteggendo il codice o se stanno semplicemente passando.
Partendo dai limiti della code coverage, vediamo come strumenti come Stryker.NET possano introdurre piccoli errori controllati nel codice per verificare se i test riescono a intercettarli.
Una puntata pensata per sviluppatori .NET che vogliono migliorare la qualità dei propri test, senza fermarsi solo alla percentuale di copertura.

it changes parts of your source code and reruns test. Ideally tests fail then, if not, then the software lacks some important tests

In a previous life, I was a big fan of #mutationtesting.
I found these two crates in #Rust for this:
* cargo-mutants: mutants.rs
* mutagen: github.com/llogiq/mutagen
Has anybody any experience with any of them? Or something else?
