Announcing behave 0.8.0: BDD-style Rust tests that compile to ordinary #[test] functions

stateruntime — Tue, 17 Mar 2026 16:42:36 +0000

Hi everyone 👋

I’ve published behave 0.8.0, a behavior-driven testing library for Rust.

The main goal is simple:

make tests easier to read and structure without introducing a custom test runtime

behave! lets you write nested scenario-style suites, and the generated tests still compile down to ordinary #[test] functions, so you can keep using normal Rust tooling and cargo test.

A few things behave focuses on:

nested, readable test groups
inherited setup / teardown
expressive expect! assertions
parameterized tests with each and matrix
tags, focus/pending workflow, and conditional skipping
optional cargo-behave CLI for tree output, JSON/JUnit output, watch mode, and tag filtering

Minimal example:

use behave::prelude::*;

behave! {
    "checkout totals" {
        setup {
            let prices = [120, 80, 40];
            let subtotal: i32 = prices.iter().sum();
        }

        "adds line items" {
            expect!(subtotal).to_equal(240)?;
        }

        "renders a receipt line" {
            let receipt = format!("subtotal={subtotal}");
            expect!(receipt).to_contain_substr("240")?;
        }
    }
}

In 0.8.0, I also added new matcher packs for JSON, HTTP, and URLs, plus more collection/path/string matchers and an each_type DSL for typed test generation.

I’d especially love feedback on:

DSL ergonomics
matcher API design
where this fits relative to more conventional Rust test styles
what feels unnecessary or too magical

Cheers!

How to be cited by ChatGPT, Gemini or Perplexity? 👾

stateruntime — Tue, 09 Sep 2025 10:33:04 +0000

SEO has changed. Again. But this time, it’s not just a new Google algorithm update or some trick with backlinks and meta tags. The whole game is shifting.

Why? Because people aren’t only “Googling” anymore. They’re asking AI search engines like ChatGPT, Perplexity, and Claude. They’re typing natural questions, and expecting answers that already pull from the best sources online.

If your brand, your business, your name isn’t part of that pool… you’re invisible.

That’s where Modern SEO comes in.

Haven't seen any discussion about it here on dev.to yet. So let's start one 👇

Have anyone of you experimented with visibility in AI Search Engines like ChatGPT, Perplexity etc? What did you learn?

Btw, I’m currently writing a book called Modern SEO for AI Search Engines: How to Show Up in ChatGPT, Perplexity, and Gemini Search Results?

I’m pulling together strategies, playbooks, and examples on how to actually show up where people are looking today.

If you want to be notified when the book is out, you can join the waiting list. And as a bonus for joining, you’ll get access right now to one of the new additions I’ve made to the book:

The High-Authority Domain List by Business Domain - a list of the exact platforms where you can create profiles, post content, and drop backlinks that actually matter.

Consider it a raw sneak peek from the book (additional part put at the end of it). The full thing is coming soon, but you don’t have to wait to start building visibility that AI will notice.
