Prerequisites

• A relatively up-to-date installation of nodejs
• NPM package manager (bundled with newer versions of nodejs)

Getting set up

Grab the client with npm install -g coderetreat

Starting a session

Tests and code live in the same file. To get started you might use the following template:

describe("numbers", function () {
  it("should be themselves", function () {
    (getANumber()).should.be.exactly(12);
  }
}

function getANumber(){
  return 12;
}

Running tests

Run cr path/to/my/session.js. The client will watch the file for changes and print the results to the terminal. When your tests fail the details will also be printed.

Writing tests

We're using mocha and should.js, and these are included by default in your environment so you can just start hacking.

Check out the should.js page for examples of how to construct assertions.
