The Laravel News site has posted a review of "Test Driven Laravel", a course from Adam Wathan walking you through the creation of a Laravel-based application from a completely Test-Driven Development approach.
I’ve been programming for close to a decade, and I’m constantly trying to find ways so to improve my skill set to be able to keep up with the ever-changing landscape of technology. The one area I’ve always wanted to improve in has been testing. [...] When Adam announced at Laracon that he was creating a course on building real-world applications with TDD, I was really excited to see where it would go.
Over the past couple of months, I’ve been lucky enough to preview the course as the lessons get finished. It’s been really helpful because I’ve been working on a large, complex application, and I’ve been able to apply the things I’m learning immediately in my day-to-day work.
The review goes on to talk about some of the things they've learned already from the course including test coverage for parts of the app that work with 3rd party services. They link to this talk from Adam as an example of some of the concepts taught in the course and, of course, a link where you can purchase your own Early Access pass and start learning.
