node package manager



A javascript testing library.

Warning: Install at your own peril! This project is brand new and nowhere near ready!

Important: All test files must end in .test.js, the runner executes a find command with that extension

Note: As specified in engines, Node >=6.4.0 is required as ES6 Proxies are currently being used

Note: If you run the tests for cashmere, some of them fail intentionally to show FAIL output

To install:

yarn add cashmere
npm install cashmere

Here is an example of a test person.test.js:

describe('person', () => {
  context('#firstName()', () => {
    it('Should get first name', () => {
      expect({ hello: 'world' }).to.deep.equal({ hello: 'world' });
    it('Should get middle name', () => {

Note that you don't have to import anything, including expect.

Here is an example of an asynchronous test websites.test.js:

describe('websites', () => {
  it.async('Facebook', (done, request) => {
    request.get('', (err, res) => {
  it.async('Halis Technology', (done, request) => {
    request.get('', (err, res) => {

For async tests it's it.async instead of it. Note that you don't have to import anything, including request.

Current Features

  • Unit tests
  • Mocha style describe/context/it
  • Async tests (brand new so use at your own peril)
  • Automatically compiles tests written in ES6
  • No special unicode characters in test output that don't display correctly in CI servers
  • No hiding logging statements
  • Clean stack traces
  • Diff output

Future Goals

  • Performance (may need parallel runs at some point)
  • Setup a global Redux-like store and have access to it from every test
  • Experiment with different testing styles
  • Probably need to store the output of asynchronous tests until done is called and then flush it all to the console at once

Note: In the tests you DO NOT need to import the following:

  • describe
  • context
  • it
  • expect
  • request
  • By
  • until

These are provided for you by default.

If you are using ESLint then put the following in your .eslintrc:

    "expect": true
    "mocha": true

Note: This all works on Mac right now, Windows support could be added at some point
