@MikeSutcliff @thoughtworks Nice to see mutation testing and pitest back on the radar, obviously more relevant than ever in the era of AI generated code and tests.

Just published a short blog post on how to use some new features in pitest and arcmutate to tune your build.

For anyone interested in trying out arcmutate, you can find more info here

Nice write up from Mahak Tripathi at @Atlassian on setting up Arcmutate for mutation testing Java and Kotlin.

That's pitest 1.18.0 syncing through to maven central

It was finally time to say goodbye to Java 8 and some of the crustier older code. Looking forward to enjoying some of the benefits that came with 9, 10 and 11.

@mpredli @Java_Champions @khmarbaise Congratulations!

@theLucyStrange "Gadzooks" gave me instant Rentaghost shivers.

@sarahdkfulton Thanks, but I don't need luck. I need blackmail material on a commissioning editor.

[Henry Coles @_pitest]

My first book is on submission.

Wish me luck or, better yet, force your friend who's an editor at a big 5 publisher buy it.

I’m now at end of life care - palliative care-and will be going into a hospice for the foreseeable - thanks to everyone who sends me love and support- you’ve been amazing

@smaychel Congratulations!

@nathanmarz Modern tools don't run the full suite against each mutant, instead they target the tests using standard line/block/statement coverage.

A talk I used to give shows how pitest (tool for Java) reduces 3 *day* analysis times from tools like Jester down to 3 minutes.

Does anyone happen to know of any good resources on the internals of @robolectric?

I'm having a poke around, but a map or guide would be handy.

[Henry Coles @_pitest]

Hot on the heels of last week's pitest release, we have another one.

Friends, do you use mutation testing with your Java apps?

I want to write an article, but need understand the relevance first 🙃

Tangent Online bitched about the chess moves I used in "The Immortal Game", apparent not realising that I used the exact moves made (up until the point things get gruesome in story) by real masters (Topalov and Kasparov, 1999).
It's ranked as the #1 chess game of all time 🤣

[Henry Coles @_pitest]

And of course, having released yesterday I now see there is a better more complete solution.
