Mutation testing - Wikipedia

to check if software tests are working properly you can use #mutationtesting
it changes parts of your source code and reruns test. Ideally tests fail then, if not, then the software lacks some important tests

Think 95% coverage means your tests are bulletproof? Think again.
In this Quarkus + Java tutorial, mutation testing exposes weak spots and shows how to fix them.

I wonder if (1) any one has done any study on the strength of type declarations on a program (or strength of types in general) and (2) if there are other metrics one could use for evaluating the strength of types.

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?

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.
