Taylor Ren has written up a new tutorial for the SitePoint PHP blog today walking you through a method for functional testing a Symfony application with the help of Symfony's own "WebTestCase" functionality.
In my previous article, we demonstrated how to load sample data into our Symfony development environment. The test data may not be useful as it stands on its own. When coupled with Functional Testing, however, it becomes a life saver. [...] Functional Testing is different. We don’t look at the “correctness” of a single function, which should be verified by a Unit Test, but look at the bigger picture. The question answered by Functional Testing is: Is our app performing well in the sense that it displays the right content, corresponds to a user’s interaction, etc?
He shows how to create a simple WebTestCase-based test to fetch the main page of a site, locate a few pieces of information and click on a certain link. Once this test passes, he adds a bit more to the test, checking the data in the page following the click.
