Hi everyone, Maelstrom is a suite of tools for running tests in hermetic micro-containers locally on your machine or distributed across arbitrarily large clusters. Maelstrom currently has test runners for Rust and Python, with more on the way. You might use Maelstrom to run your tests because: * It's easy. Maelstrom functions as a drop-in replacement for cargo test and pytest. In most cases, it just works with your existing tests with minimal configuration. * It's reliable. Maelstrom runs every test hermetically in its own lightweight container, eliminating confusing errors caused by…

We'd love to share our work with you: Restate, a system for workflows-as-code (durable execution). With SDKs in JS/Java/Kotlin and a lightweight runtime built in Rust/Tokio. https://github.com/restatedev/ https://restate.dev/ It is free and open, SDKs are MIT-licensed, runtime permissive BSL (basically just the minimal Amazon defense). We worked on that for a bit over a year. A few points I think are worth mentioning: - Restate's runtime is a single binary, self-contained, no dependencies aside from a durable disk. It contains basically a…

I built BuzzBench because I was frustrated with how complex performance testing tools have become. And I was ending up writing my own scripts to test endpoints and manually check out resource usage at the time of testing. Checkout demo: https://www.youtube.com/watch?v=yAnbZMoQvmQ

I got sick of the old software development loop: Change code -> Run tests -> wait -> wait some more -> look at failures. I decided to build a tool that will enable you to: Change code -> look at failures. No wait time, no explicit test running. Under the hood: - Runs the whole test suite and collects code coverage per test. - For each auto file save, analyzes the changes on the tests. - Runs changed tests in the background. - Display results, the loop time from change to test results is approx 250ms. Instead of: code -> alt+tab -> arrow up -> rerun all the tests -> wait ... -> test results…

I always strive to write better, clean and readable code. But I often find unit tests are hard to read, and especially harder to quickly identify what are the important pieces, or even what the test is testing about. So I came up with this lightweight library to help enforce unit tests with a Given-When-Then structure. I hope you find this useful. Any feedback are welcome. https://github.com/cobrakai-lab/Cobrakai.GWTUnit
