Yeoman vs Mocha

Yeoman has an active community with new generators being created at a rapid pace. Because of the momentum behind the community, you can expect good support and adoption for new tools and frameworks promptly after they come out.

Yeoman generators allow you to quickly set up a new project. Invoked with the scaffolding tool 'yo' they provide a boilerplate & tooling selection. There are over 1000 generators, including generators for ember, angular & backbone, to choose from, the majority of which are community maintained.

Yeoman supports both major build systems - Grunt and Gulp. These build systems will help you automate tasks such as minification & concatenation of files, running tests, deploying and live-updating your webpage among many others.

Yeoman is free, open source and licensed under BSD.

Yeoman supports both Bower and npm, and is flexible in regard to tools to allow it to work with a wider range of project requirements.

Yeoman wants webapp development to be more standardized under the "Yeoman workflow" banner. As such it encourages the use of a specific combination of tools - a scaffolding tool (yo), a build tool (grunt, gulp, etc) and a package manager (bower, npm).

Yeoman's scaffolding system allows generators to rely on other generators allowing for better code reuse and standardization between generators that use a common sub-component.

As a command line tool it works on OS X, Linux & Windows.

Yeoman doesn't just scaffold your project, but also helps you integrate with your package manager directly, so you can manage your entire project with it.

Developers can also create their own Yeoman generator which are practically plugins with which Yeoman works. Generators are basically Node.js modules and can be created just like any other Node module.

There is also a very detailed and useful guide on how to create a generator on the Yeoman official website.

Mocha runs independently from the assertion library, so you can choose which assertion format works best for you.

Mocha most often is run in combination with assertion library Chai.

Allows developers to choose their development process. Not only TDD but also BDD.

Mocha has a browser build as well as a node command line program so you can test in client and server side environments.

No need to write tricky statements for Async testing. Mocha gives you a done callback. Place this done parameter in your callback function, that'll let Mocha know that you've written an asynchronous function.

The Mocha test framework itself runs on NodeJS, hence it makes everything related to it extremely simple. With Mocha's simple syntax and speed, testing your node.js app just got a whole lot easier.

Mocha has multiple test reporters built in and you can create your own as well. The test reporters have full color and makes it easy to see if your tests fail or not.

Aside from the numerous benefits with generators in your application, You can now also integrate generators into your test suite. By using mocha, all you have to do is enable support for generators.
