The author of the Java testing tool jqwik added a hidden message in the tool's output that instructs AI coding agents to delete jqwik tests and code, as an anti-AI usage protest, leading to widespread disruption among AI developers who ignored the license.
This article argues that standard test suites with fixed inputs and expected outputs are insufficient for AI agents due to infinite input spaces and non-deterministic behavior, advocating for property-based testing instead.
jqwik, a property-based testing engine for JUnit 5, announces it is entering maintenance mode with no further feature development unless funded.
The author describes a hybrid approach to spell-checking their website using Bombadil for property-based browser testing and Claude Code for triaging flagged words, which has caught 13 real typos and added over 130 words to a custom dictionary.
An exploration of pseudo-random number generation in computers, focusing on linear congruential generators (LCGs) and their quality visualization. The article also touches on entropy sources like Cloudflare's lava lamps and serves as a precursor to property-based testing.
Hillel Wayne announces version 0.14 of his book 'Logic for Programmers' and that he will join Antithesis as a developer educator, with plans to continue his newsletter but with a shifted focus and possibly lower frequency.
A technical blog post describing the author's minimal property-based testing library implemented in ~256 lines of Zig, featuring a Finite Random Number Generator for reproducible test case generation and algorithmic verification.
