Agile Web Application Development with Yii1.1 and PHP5

Overview of this book

This book is a step by step tutorial in developing a real-world application using the incremental and iterative approach to software development. You learn about agile software development by leaning on the agile nature of the Yii application development framework. You touch on each aspect of the software development lifecycle by building a project task management application from concept through production deployment.After a brief, general introduction to the Yii framework and outlining the software development approach taken throughout the book, the chapters break down in the same way as software development iterations do in real-world projects. After the 1st iteration, you will have a working and tested application with a valid, tested connection to a database.In the 2nd and 3rd iterations, we flesh out our main database entities and domain object model and become familiar with Yii's object-relational-mapping (ORM) layer, Active Record. We also learn how to lean on Yii's auto-generation tools to automatically build our create/read/update/delete (CRUD) functionality against our newly created model. These iterations also focus on how Yii's form validation and submission model works. By the end of the third iteration you will have a working application that allows you to mange projects and issues (tasks) within those projects.The 4th and 5th iterations are dedicated to user management. We learn about the built-in authentication model within Yii to assist in application login and logout functionality. We then dive into the authorization model, first taking advantage of a Yii's simple access control model, then implementing the more sophisticated role-based access control (RBAC) framework that Yii provides.By the end of the 5th iteration, all of the basics of a task management application are in place. The next several iterations are focused on the nice-to-haves. We add user comment functionality, introducing a reusable content portlet architecture approach in the process. We add in an RSS Web feed and demonstrate how easy it is to integrate other third-party tools within a Yii application. We take advantage of Yii's theming structure to help streamline and design the application, and then introduce Yii's internationalization (I18N) features so the application can be adapted to various languages and regions without engineering changes.Finally, we turn our focus to production deployment. We introduce ways to optimize performance and security to prepare the application for a real-world production environment.

Testing in Yii


As of version 1.1, Yii is tightly integrated with the PHPUnit (http://www.phpunit.de/) and Selenium Remote Control (http://seleniumhq.org/projects/remote-control/) testing frameworks. There is nothing about TDD that presupposes a particular testing framework (or any testing framework at all, for that matter), but using one is strongly recommended.

You may certainly test Yii PHP code with any of the testing frameworks available. However, the tight integration of Yii with the two frameworks mentioned previously makes things even easier. And making things easy is one of our primary goals here. We will be using the testing features of Yii as we proceed.

When we used the yiic webapp console command to create our new Hello World demo application in Chapter 2, we noticed that many files and folders were automatically created for us. The ones among these relevant to writing and performing automated tests are the following:
