The repeat-test library is my attempt to come up with a nicer API for writing property tests in TypeScript.
While well-tested, this library is new and incomplete. I use it in my own projects, but haven't heard of anyone else using it. For now, this library only works with Deno.
The API should be considered unstable. I like to rename symbols when I think of a better name and might still make major changes before it reaches 1.0 (if it ever does).
So if you use it, I recommend pinning to a specific version. Perhaps using a coding agent will make upgrades easier?
If you're looking for a full-featured, popular, stable property-testing library, I recommend fast-check.
The main entry point is the repeatTest function. Here's how to use it as a
glorified while loop:
import{assertEquals}from"@std/assert";import{repeatTest}from"@skybrian/repeat-test";constexamples=["hello","world"];repeatTest(examples,(word)=>{assertEquals(word.length,5);// This will run twice.});The first argument to repeatTest provides a way of generating examples. The
second argument is a test function to run repeatedly that takes an example as
input. A repetition ("rep" for short) passes if the test function completes
normally.
See the docs directory for a longer introduction.
