Creating a Magento test case
As this is the last chapter of this book, we will write a test that we can execute with the Magento Testing Framework. This framework uses PHPUnit to execute the tests.

Getting ready
In this recipe, we will create a unit test for the Packt_HelloWorld module that we created in Chapters 4, Creating a Module, Chapter 5, Databases and Modules, Chapter 6, Magento Backend, and Chapter 7, Event Handlers and Cronjobs.
