On the TutsPlus.com site they've posted a new tutorial showing you how to do test-driven development with Laravel and Doctrine, making use of Doctrine's own testing functionality inside of a Laravel application for PHPUnit based unit testing.
As a PHP developer, you may use the Test-Driven Development (TDD) technique to develop your software by writing tests. Typically, TDD will divide each task of the development into individual units. A test is then written to ensure that the unit behaves as expected. [...] TDD verifies that the code does what you expect it to do. If something goes wrong, there are only a few lines of code to recheck. Mistakes are easy to find and fix. In TDD, the test focuses on the behavior, not the implementation. TDD provides proven code that has been tested, designed, and coded.
[...] PHPUnit is the de-facto standard for unit testing PHP. It’s essentially a framework for writing tests and providing the tools that you will need to run tests and analyze the results. PHPUnit derives its structure and functionality from Kent Beck’s SUnit.
He briefly talks about some of the assertions that PHPUnit has to offer before getting into the support that Laravel includes and how to configure it so Doctrine can work with your database. He then talks about Doctrine, briefly introducing the popular database abstraction tool and how to integrate it with a Laravel application. From there he starts in on the tests themselves, showing code that uses fixture data to create several tests for Post and Comment data.
