PHPUnit Code Sprint at trivago Offices, Oct. 13th/14th

You do not run a successful, stable software project over several years without some amount of automated testing. If several dozens of developers are working on the same code base, the need for test automation becomes even greater. After all, their changes might have unintended effects on other people's code, or on certain edge cases that will not be noticed until the changes go live — and maybe not even then.

And because we truly love open source we’ve also open sourced our solution to speed up multi-compiler builds, which we rely on heavily to deliver ideal bundles to our users.

With this article I would like to share the reasons for the migration as well as our experiences and lessons learned.

Reportoire, the journey to data source independency

Concepts like separation of concerns, logic decoupling or dependency injection are things we developers have heard more than a couple of times. At trivago, the Android app is developed using the Model View ViewModel (MVVM) architecture, aiming for views as dumb as possible, leaving the decision making to the view models. This leads to an increased test coverage since testing logic in views is something we can’t do that easily.
