Testudo Build Status

Testudo

Testudo is a Yeoman based project scaffolder for the building of modern, modular, testable web applications. Testudo has first class support for all of the modern tools you know and love such as RequireJS, CoffeeScript, Karma, Grunt, Bower, SASS, Stylus and many more.

Quick Start

Prerequisites

Install Testudo

$ npm install -g yo 
$ npm install -g generator-testudo
$ yo testudo 

Start watcher/server

$ testudo

Key Features

Modular Focus

Testudo is heavily influenced from my experience in building modular web applications. The key to building any large scale web application in JavaScript is to not, instead our focus should be on creating modular widgets that operate independently of the larger application.

In Testudo the creation, testing, management and optimization of these widgets is made possible by Testudo's tooling. Testudo is a series of tools and practices around modular app development.

Key Features

  • Module scaffolder to dynamically create and integrate new modules
  • BronsonJS management layer for modules
  • First class testing for both unit through Karma and acceptance through CucumberJS
  • Full AMD compatibility with RequireJS
  • Choice between SASS and Stylus for CSS preprocessor
  • Choose between first class CoffeeScript support w/linting or JavaScript w/linting
  • Extensible clean GruntJS tooling
  • Integrated environment and user configuration with nconf

Test First

Testudo understands how important testing is and how frustrating it can be to setup a consistent reliable testing framework. Testudo has full support for the writing of unit tests anywhere in the app/modules/. In addition, unit testing dependency injection is made easy by full RequireJS support in all your test specs. Finally, Testudo has full support for Sinon, Chai, Jquery-Chai and Sinon-Chai. Testing has never been this easy.

Key Features

  • Write your unit tests in full AMD
  • Optionally write your tests in CoffeeScript
  • Karma Test Runner
  • Chai Assertions with Chai-Jquery and Chai-Sinon
  • Sinon for mocks and stubs

Modern Tooling

Testudo comes loaded with an opinionated set of tools and libraries that I believe reflect some of the best of the modern tool sets made available to front end developers. Tools like RequireJS and testing and core to Testudo and treated as first class citizens instead of afterthoughts.

Key Features

  • Full application code support for CoffeeScript
  • Grunt files and tasks all written in CoffeeScript
  • Unit test CoffeeScript and RequireJS support
  • Optional Compile time linting with CoffeeLint

Battle Tested

Testudo is an attempt at offering a solid opinionated boilerplate based on my personal experience developing tools and processes for enterprise web sites.

Testudo is designed to be used by a team in a real work environment. Testudo comes customizable to better fit your company, business, client or even team member through extensible setup and run time configuration.

Key Features

  • Project and module scaffolder through yeoman
  • Configure everything from folder, ports, live-reload settings all from a single user configuration file
  • universal accepted naming standards and conventions for structure
  • organized and maintainable grunt tasks and options

Modules

Testudo enables the easy construction of a framework agnostic module application framework. The focus of Testudo is the module and how those modules become the building blocks of your large scale web application.

What is a Module

A Module is a standalone self sustaining component with limited knowledge of the greater system in which is operates. Modules by design are loosely coupled and therefore a system comprised of modules is less brittle than one that is not.

Modules in Testudo reside in the app/modules/ directory and are automatically added to r.js and imported into the main stylus stylesheet. A Module in Testudo can be anything from a single script file to an entire MVC application written in Backbone or something similar.

Here is an example of what the modules directory could look like.

app/
  |- modules/
  |  |- moduleA/
  |  |  |- models/                   // Backbone (or similar) models
  |  |  |- templates/                // external templates (underscore, handlebars etc)
  |  |  |- views/
  |  |  |  |- mainView.js            // Backbone (or similar) view
  |  |  |- main.js                   // module entry point (optionally BronsonJS)
  |  |  |- main.stylus               // module specific stylesheet

BronsonJS

To better support the isolation and loose coupling of modules in your system Bronson acts as an intermediate layer managing the relationships between your other modules and offering granular control over the life cycle of all the modules in your application.

This all starts with the Bronson.Module object which is the entry point into your module and itself acts as a mediator to the inner workings of your module.

Below is an example of what a Bronson module looks like.

# 
# Instagram Module 
# 
# Sample Bronson Instagram module 
# 
define [
  'jquery'
  'underscore'
  'backbone'
  'marionette'
  'modules/instagram/collections/photosCollection'
  'modules/instagram/views/photosView'
]($, _, Backbone, Marionette, PhotosCollection, PhotosView) ->
  class InstagramModule extends Bronson.Module
    # Inner module controller 
    events:
      'instagram:stop': 'stop'
      'instagram:start': 'start'
      'map:geoupdate': 'update'
 
    # 
    # load the application 
    # 
    onLoad: (data) ->
      @data = data
      App = new Marionette.Application()
 
    # 
    # listen for notifications and prepare view 
    # 
    onStart: ->
      @photos = new PhotosCollection()
 
      @photosGridView = new PhotosView
        el: @data.el
        collection: @photos
 
    # 
    # stop subscribed notifications 
    # 
    onStop: ->
      Bronson.unsubscribe 'instagram:map:geoupdate'
 
    # 
    # stop all notifications and unrender the module 
    # 
    onUnload: ->
 
    # 
    # on position change fetch new photos 
    # 
    update: (data) ->
      @photos.fetch
        data:
          client_id: "b3481714257943a4974e4e7ba99eb357"
          lat: data.lat
          lng: data.lng
          count: 12
        reset: true
        success: =>
          @photosGridView.render()

R.JS

Testudo works with the R.JS (RequireJS build tool) to automatically build modules as separate packages reducing the footprint of your application on initial load. By following the convention of putting each module in app/modules/ Testudo will find each main.coffee and add it to the modules list in R.JS excluding all application code in app/main.coffee. This is done automatically and no customization of the R.JS build configuration is necessary.

The benefit of this is you download just the base application code up front and using RequireJS asynchronously fetch your modules as needed through Bronson.

SASS

Testudo works with Sass-Globbing to automatically include all module specific SASS into your main SASS stylesheet.

Stylus

Stylus automatically includes globbing import support. All stylus files in the modules/ directory will be automatically included in your main stylesheet.

Testing Modules

Testudo has a customized RequireJS Karma runner to find all test specs following the convention of **/*Spec.coffee in your app/modules/ folder and running them with Karma in the testudo test:unit task.

Because Testudo uses Require to load test specs your specs themselves should be wrapped in a define block and should use RequireJS to load the objects to test. This allows granular unit specific testing and allows for much greater flexibility in substituting mocks through dependency injection.

My convention is to put all my tests in a test/ folder inside of app/modules/moduleA/ but you may put yours anywhere so long as they are in the app/modules folder.

Configuration

User Settings

Included in the project is a user-settings.json file for making custom changes to your workspace. It is important that after changing this file to suit your needs that you do not check it in. Run the following snippet to mark a file as untracked.

$ git update-index --assume-unchanged user-settings.json

Grunt Tasks

In an effort to make the Grunt files more maintainable and readable I've implemented many of the great ideas by Thomas Boyt in his article on maintainable grunt files.

Roadmap

  • [0.2.0] - further optimization of runners
  • [0.3.0] - addition of acceptance testing
