Feature: helper spec
Helper specs live in spec/helpers. In order to access
the helper methods you can call them on the "helper" object.
Scenario: helper method that returns true
Given a file named "spec/helpers/application_helper_spec.rb" with:
"""
require "spec_helper"
describe ApplicationHelper do
describe "#page_title" do
it "returns true" do
helper.page_title.should be_true
end
end
end
"""
And a file named "app/helpers/application_helper.rb" with:
"""
module ApplicationHelper
def page_title
true
end
end
"""
When I run "rspec spec/helpers/application_helper_spec.rb"
Then the output should contain "1 example, 0 failures"
Scenario: helper method that accesses an instance variable
Given a file named "spec/helpers/application_helper_spec.rb" with:

assign(:title, "My Title")
helper.page_title.should eql("My Title")
end
end
end
