HN discussion(Disclosure: I’m an Antithesis employee.) The blog post is meant as a high-level introduction for a general audience. The documentation ( https://antithesis.com/docs/ ) goes into considerably more detail about what kind of configuration and setup you need to start testing with Antithesis.

HN discussionDepends on how far you mean with "advanced" here. We specifically cover the differences between Antithesis and Chaos Engineering in our "How It's Different" page: https://antithesis.com/product/how_is_antithesis_different/ Here's the relevant text though: Antithesis testing resembles chaos testing, in that it injects faults to trigger and identify problems. But Antithesis runs these tests in a fully deterministic si…

HN discussionAntithesis here - curious what part of the Getting Started doc gave you that impression? If you take a look at our How Antithesis Works page, it might help answer you question as to how Antithesis is different from just bundling your unit tests. https://antithesis.com/docs/introduction/how_antithesis_work... In short though, unit tests can help to inform a workload, but we don't require them. We autonomously explore…

HN discussionI got really excited about this, and I spent a little time looking through the documentation, but I can't figure out how this is different than randomizing unit tests? It seems if I have a unit test suite already, then that's 99% of the work? Am I misunderstanding? I am drawing my conclusions from reading the Getting Started series of the docs, especially the Workloads section: https://antithesis.com/docs/getting_st…

HN discussionPost author here. Sorry it was vague, but there's only so much detail you can go into in a blog post aimed at general audiences. Our documentation ( https://antithesis.com/docs/ ) has a lot more info. Here's my attempt at a more complete answer: think of the story of the blind men and the elephant. There's a thing, called fuzzing, invented by security researchers. There's a thing, called property-based testing, inve…

HN discussion[I work at Antithesis] The system can certainly revisit a previous simulated moment and replay it. And we have some pretty cool things using that capability as a primitive. Check out the probability chart in the bug report linked from the demo page: https://antithesis.com/product/demo

HN discussionAphyr didn’t test foundation himself, but the foundation team did their own Jepsen testing which they reported passing. All of this was a long time ago, before Foundation was bought by Apple and open sourced. Now members of the original Foundation team have started Antithesis ( https://antithesis.com/ ) to make it easier for other systems to adopt this sort of testing.
