Instance Attribute Details

#proxy ⇒ Object

We have to reset the RSpec.configuration, because it contains a lot of information related to the current test (what’s running, what are the different test results, etc).

RSpec.configuration gets also loaded with a bunch of stuff from the ‘spec/spec_helper.rb’ file. Often that instance is extended with other modules (FactoryGirl, Mocha,…) and we don’t want to replace requires with load all around the place.

Instead, we cache whatever is done to RSpec.configuration during the first invokration of require(‘spec_helper’). This is done by interposing the Proxy class on top of RSpec.configuration.
