Mutation tests

[jesusgalhub]

Is there any plan to implement a "mutation testing" strategy or collaborate with strykerjs so they support Rstest?

Strykerjs looks interesting, and Rstest can certainly be supported. However, since Rstest is not yet at version 1.0, the API is likely to change, so we won't be providing official support this early. i'm also curious, how effective do you find strykerjs in actual use? especially when used with an agent, is the effect even better? Thank you.
