Unitest

Deno-first universal unit testing framework

🚧 This is beta

Features

• Like jest but not jest
  You can express declarative tests around the symbolic expect in jest. Also, all matchers are composable and customizable. jest and jest-extended matchers are provided as presets.

• Universal
  It is designed for use with Deno first and foremost.
  It is also compatible to work in browsers and Node.js environments.

• Compositable
  Unitest is also intended to be used in a browser.
  For this reason, we provide a composable interface to keep the bundle size as small as possible.

• TypeScript-first
  Type-safe tests can be expressed. A type filter restricts the availability of only those matchers that satisfy the data type under test.
  It also keeps the bundle size small by transferring part of the data type validation to TypeScript.

Getting Started

Visit https://unitest.vercel.app/ to get started with Unitest.

Quick view

import { expect, it } from "https://deno.land/x/unitest@$VERSION/mod.ts";

it("should not equal", () => {
  expect("Deno").not.toBe("Node");
});
