Book Review: Testable JavaScript

By Mark Ethan Trostler
Publisher: O’Reilly Media
Released: January 2013
Pages: 274

Chapters:

Chapter 1 Testable JavaScript
Chapter 2 Complexity
Chapter 3 Event-Based Architectures
Chapter 4 Unit Tests
Chapter 5 Code Coverage
Chapter 6 Integration, Performance, and Load Testing
Chapter 7 Debugging
Chapter 8 Automation
First off, I want to say this is one of my favorite books. It is a great work on developing with TDD and agile with a focus on JavaScript. I am considering buying a print copy
to keep next to my computer with the GoF, Growing Object Oriented… and Release It! I am big believer in the main aim of the book to keep javascript code simple and
loosely coupled. This is not a book for those who don’t know JavaScript or have some background in Test Driven Development.

The book starts with a nice section on agile, TDD, BDD , the why’s, what’s and how’s of all the best practices for modern development. There is a very thorugh discussion of a
number of great development tools including: JSLInt, JSmeter, JSCheckStyle, YUIDoc and JSDoc. This book is great for Java developers wishing to start doing enterprise level
JavaScript on the client and server and in-between (Meteor / Derby).

I like this book also for it’s thorough coverage of best modern development practices: Code Reuse, Coupling, Metrics, Dependency Injection, auto documenation (think javadoc),
formalized softwtare inspections, coder coverage, fan-out/fan-in nd more agile practices.

One of the other strong topics in the book is Event-Based Architectures / programming. Event-based programming is great for decoupling objects. There is also great information on using and Event-Hub and socket.io as well.

isolation
scope
mock objects

Node.js Development on Windows with WebMatrix 2

Oct17

Having found the excellent TOAD for MongoDB (and other NoSQL), Windows is starting to be an okay development platform. Not as good as Mac or Ubuntu, but not bad. From Eclipse to SBT to GIT to BASH, everything you need for Node.JS, HTML5, Mobile, NoSQL and Cloud PAAS development is available.

WebMatrix 2 lets you edit JavaScript, Node.js with, HTML5, CSS, Less, CoffeeScript, Images and connect to MySQL.

Test Driven Node.JS Development

Aug30

What would a language and framework be with unit testing, BDD, and other testing methods, frameworks and systems?

So once you get beyond casual Node.JS development, you will need to start unit testing. Node.js has a surprisingly robust and mature set of testing tools and options. Out of the box, Node.js has Built In Assert which will let you do some basic XUnit style tests. A step beyond that is NodeUnit, which is pretty easy to use for XUnit oriented people. For me, it’s easy to pick up coming from doing a lot of JUnit tests. This article is great for Using NodeUnit for Testing. Node.js is great because so many people have developed tools, frameworks and utilities for it. The only issue I have it some are not very mature and the options are so fragmented. There’s no Spring framework or hibernate that garners massive usage. So many variations and options, I wish they could work together to put together a killer Rails or Spring type group of mature, tested, interconnected tools and utilities. Full Testing Suite – Mocha is installable via NPM and works with a CI server. This one is pretty cool.

The source for everything testing/bdd/mocking for Node.JS is Joyent’s Testing Wiki.

There’s a number of behavior driven development tools including the polyglot tool Cucumber -> BDD Testing Tool – Cucumber.JS. Another option is Asynchronous BDD Testing Tool – Vow.

For mocking, Mockito Style Mock Objects – Mary Jane, looks great. I will hope that maybe Mockito will officially support this one.

For JQuery fans, someone has ported QUnit to Node.JS [Node-Qunit]

Virile Testing for Node.JS Apps is pretty interesting and so is Headless Full Stack Testing with Zombie.js.

This is just a sampling of test options. Obviously tools like Selenium and Firebug will help you and so would JMeter and and SOAPUI. A lot of general web testing tools are available that can do full system testing or integration testing for your Node.JS web apps.

I will be adding some examples in a future post with a github link.

Nodester Node.JS + Express + Mongo App Part 1 – Nodester

Aug2

The Running Node.JS Application on a Nodester

I am still working on putting up a full application for the tutorial. Also I will try the same application on Nodejitsu, CloudFoundry and Heroku.

The following are the basic steps for working with Nodester. It is very similiar to all the other command-line PaaS interfaces. I am running this on
Windows, but it will work in most environments.

npm install nodester-cli -g
nodester user setup &lt;username&gt; &lt;password&gt;
nodester user setkey c:.sshid_rsa.pub
nodester app create &lt;appname&gt;
nodester app init &lt;appname&gt;
nodester npm install express
nodester npm install mongoose
nodester npm install socket.io

git add .
git commit -am "Ready to deploy"
git push nodester master

nodester app info
nodester app stop|start|restart
nodester app logs

For nodester they push to master for Nodester to get a new build.

Log into your Application List Page on the Administration Site for Nodester and you will see your newly added Application. Nodester has a good help system that will be useful to you while learning. The git commands are standard GIT which makes using all the cloud systems pretty similiar.

After uploading, I check the logs for errors:

nodester app logs
nodester info Showing logs for: rollerderby
New PID: 18884
chroot_runner
chroot_runner
Spawing /app/server.js
Running node v-0.8.1

App listening on port 19885

nodester info ok!
