Unitest

Deno-first universal unit testing framework

🚧 This is beta

• 🦕 Deno-first
  It has been designed with Deno first, and actively uses the Deno Runtime API.

• 🌎 Universal
  It is also compatible to work in browsers and Node.js environments. Use the compatible compat module instead of the Deno Runtime API.

• 🃏 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.

• ♻️ 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.

• 🐺 Isolated
  Each module is independent, with no dependency on context. This means that they can be combined with any module.

• deno 1.15+

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

All available matchers

import { expect, test } from "https://deno.land/x/unitest@$VERSION/mod.ts";
test({
  name: "should not equal",
  fn: () => {
    expect("Deno").not.toBe("Node");
  },
});

then, deno test

Currently the test runner CLI relies on the Deno CLI. This is subject to change in the future.
