Class Method Details

.run_in_process ⇒ Object

rspec defines a crapton of global information and doesn’t clean up well between runs. This means that there are global objects that leak and chew up memory. To counter that, we fork a process to run the spec test.

This also allows us to load different versions of Puppet so users can select the version they want to validate against.
