Deno-first universal unit testing framework

jest like testing easy

:construction: This is still beta

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

expect("").toBe("");

Custom matcher

It provides custom matcher interface.

You can add custom matcher easy. The type is automatically extended.

import { defineExpect, jestMatcher } from "https://deno.land/x/unitest@{VERSION}/mod.ts";

const expect = defineExpect({
  ...jestMatcher
  toBe100: (actual) => {
    if (actual === 100) return { pass: true };
    return {
      pass: false,
      message,
    };
  },
});

expect(1000).not.toBe100();
