We all say that we should make tests, but writing good tests can be hard though. You want to thoroughly test your work, but you can't hammer it with all sorts of values to make sure it handles different cases properly...or can you? Welcome to the world of fuzz testing!
Fuzz testers are designed to randomly create data to test your software against. Making sure it passes (and fails) with a bunch of different kinds of inputs will help identify edge cases in your software. Writing your own value generators can be hard though, so why not use ours? This library's goal is to make good testing more accessible and easy to use. Just need a simple value, like a number? We got you covered. Want to create an object with other objects in it? No problem. Want to generate full structures conditionally with varying fields and types? Yep, we thought of that, too. By combining primitives and transforming them, same as you do when writing code in JavaScript or TypeScript, you can build a fuzzer for any occasion. Speaking of, did we mention it's all typed, too?
So now we have no more excuses; we can write good tests to make good code! Okay, maybe less execuses. ;-)

elm-test is a huge inspiration for the library. This likely wouldn't exist without all the hard work of those who have built and contributed to it.

Elm for changing the way we think about how to design and create software. It has made programming fun for us again and we're constantly delighted by the lessons learned.
