Micro-should NPM

micro-should

Simplest zero-dependency testing framework, a drop-in replacement for Mocha.

Supports async cases. Works with any assertion library.

should(title, case) (or it(title, case)) syntax
should.only(title, case) allows to limit tests to only one case
should.skip(title, case) allows to skip functions instead of commenting them out
describe(prefix, cases) for nested execution
should.run() must always be executed in the end
should.runParallel() for CPU-intensive tasks, would ramp up threads equal to CPU count

npm install micro-should

npm.io

Usage

const { should } = require('micro-should');
const assert = require('assert'); // You can use any assertion library (e.g. Chai or Expect.js), example uses built-in nodejs

should('add two numbers together', () => {
  assert.equal(2 + 2, 4);
});

should('catch errors', () => {
  assert.throws(() => {
    throw new Error('invalid');
  });
});

should('produce correct promise result', async () => {
  const fs = require('fs').promises;
  const data = await fs.readFile('README.md', 'utf-8');
  assert.ok(data.includes('Minimal testing'));
});

// should.only("execute only one test", () => {
//   assert.ok(true);
// });

// should.skip("disable one test by using skip", () => {
//   assert.ok(false); // would not execute
// })

// Nested
const { describe } = require('micro-should');
describe('during any time of day', () => {
  describe('without hesitation', () => {
    should('multiply two numbers together', () => {
      assert.equal(2 * 2, 4);
    });

    should('multiply three numbers together', () => {
      assert.equal(3 * 3 * 3, 27);
    });
  });
});

// Execute this at the end of a file.
should.run();
