If you’re asking, “what’s Yii?” check out my earlier tutorial: Introduction to the Yii Framework, which reviews the benefits of Yii and includes an overview of what’s new in Yii 2.0, released October 12th, 2014.
This tutorial will walk you through installing Yii 2.0, setting up your local development environment, building a simple Hello World application, setting up your remote production environment for hosting and deploying your code from a GitHub repository.

Testing approaches depend on where you are in the project and your “budget,” in terms of time, money, manpower, need, etc. Ideally, unit testing is budgeted into the development process, but realistically, we often encounter existing or legacy programs that have little or no code coverage but must be upgraded or maintained.
The worst scenario is a product that is currently being developed but exhibits an increased number of failures during its development, again with little or no code coverage. As a product manager, either at the beginning of a development effort or as a result of being handed an existing application, it is important to develop a reasonable unit testing strategy.
Remember that unit tests should provide measurable benefits to your project to offset the liability of their development, maintenance, and their own testing. Furthermore, the strategy that you adopt for your unit testing can affect the architecture of your application. While this is almost always a good thing, it may introduce unnecessary overhead for your needs.
