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.
