Fabien Potencier has posted the eighth part in his "building a framework on Symfony2 components" series. So far he's created a full-featured microframework with routing, controllers, HTTP handling and namespaced code. In this latest part he improves the sample framework by adding some unit tests.

Some watchful readers pointed out some subtle but nonetheless important bugs in the framework we have built yesterday. When creating a framework, you must be sure that it behaves as advertised. If not, all the applications based on it will exhibit the same bugs. The good news is that whenever you fix a bug, you are fixing a bunch of applications too. Today's mission is to write unit tests for the framework we have created by using PHPUnit.

He includes the XML for a basic phpunit.xml configuration file and uses a UrlMatcher and ControllerResolver in a "Framework" class and makes the test check for "not found" URLs and for checking for a correct Response.
