Matt Stauffer continued his new series that covers the new integration testing utilities.
For a quick refresher, integration tests are those which test your entire system as an integrated application, as compared to unit tests, which test each system of your application separately.
In his first post, he covers the new integrated package. Then models and factories. Finally, finishing up with DatabaseMigrations, DatabaseTransactions, and WithoutMiddleware.
If you’d like to get up to speed on these new features be sure and check out these posts as well as his complete series on new features in Laravel 5.1.
