Login for feature test with warden test helpers

Warden provides a way to login as a user without having to go through the web interface that a user generally sees for sign in.

user = FactoryGirl.create(:user)
login_as user, scope: :user

In the config block for Rspec you would include this statement:

config.include Warden::Test::Helpers, type: :feature

If you have different models for different types of users in your system you can sign in with different scopes. Lets say you have a student user concept, you can sign in with:

student = FactoryGirl.create(:student)
login_as student, scope: :student
