Rendering Deferred Views Outside of Rails Controllers

Typically, Rails views are rendered after some controller action is executed. But the code that powers Rails controllers are flexible and extensible enough to create custom rendering objects that can reuse views and helpers, but live outside of web request processing. In this post, I'll cover what a Rails controller is and what it's composed of.

Abstract

In the manual the steps required to install headless Firefox on CentOS 6 are described. Headless Firefox may be needed to perform GUI automated testing.

All steps of this manual have been validated on CentOS 6.8. It should not be a problem to adapt the solution to other distros.

Steps

Upgrade yum
