I am following the book Jump Start Node.js and am starting to write tests with mocha. My test output should show something similar to:

3 of 3 tests failed:
1) exchange buy should add a BUY nockmarket order:
ReferenceError: exhange is not defined

But instead what I am seeing is:

npm install make test
npm http GET https://registry.npmjs.org/make
npm http GET https://registry.npmjs.org/test
npm http 200 https://registry.npmjs.org/make
npm http 200 https://registry.npmjs.org/test
npm http GET https://registry.npmjs.org/ansi-font/0.0.2
npm http 200 https://registry.npmjs.org/ansi-font/0.0.2

npm http 200 https://registry.npmjs.org/ansi-font/-/ansi-font-0.0.2.tgz

Am I missing something very simple? My test suite is as follows:

exchange.test.js

'use strict';

var assert = require('assert')
  , should = require('should');

var exchangeData = {};

suite('exchange', function() {
    test('buy should add a BUY nockmarket order', function(done) {
    exhangeData = exchange.buy(40, 100, exchangeData);
    exchangeData.buys.volumes[40].should.eql(100);
    done();
});

test('sell should add a SELL nockmarket order', function(done) {
    exchangeData = exchange.sell(41, 200, exchangeData);
    exchangeData.sells.volumes['41'].should.eql(200);
    done();
});

test('sell should produce trades', function(done) {
    exchangeData = exchange.sell(40, 75, exchangeData);
    exchangeData.trades[0].price.should.eql(40);
    exchangeData.trades[0].volume.should.eql(75);
    exchangeData.buys.volumes[40].should.eql(25);
    exchangeData.sells.volumes[41].should.eql(200);
    done();
});
});

package.json

{
      "name": "nockmarket"
    , "version": "0.0.1"
    , "private": true
    , "dependencies": {
          "jquery" : "1.7.3"
        , "mocha": "1.3.0"
        , "should": "1.0.0"

    }
}

Makefile

test:
    @./node_modules/.bin/mocha -u tdd
.PHONY: test

According to the books instructions I have Node installed correctly and I can run simple examples with no issues.

Any ideas would be very helpful.

Thanks, T.
