More about adding a collaboratorhelper spec
Helper specs live in spec/helpers
, or any example group with :type =>
. In order to access the helper methods you can call them on the
:helper
helper
object.
- Scenarios
-
- helper method that returns true
- helper method that accesses an instance variable
- application helper is included in helper object
- 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 examples should all pass
- helper method that accesses an instance variable
-
- Given
-
a file named "spec/helpers/application_helper_spec.rb" with:
require "spec_helper" describe ApplicationHelper do describe "#page_title" do it "returns the instance variable" do assign(:title, "My Title") helper.page_title.should eql("My Title") end end end
- And
-
a file named "app/helpers/application_helper.rb" with:
module ApplicationHelper def page_title @title || nil end end
- When
- I run "rspec spec/helpers/application_helper_spec.rb"
- Then
- the examples should all pass
- application helper is included in helper object
-
- Given
-
a file named "spec/helpers/widgets_helper_spec.rb" with:
require "spec_helper" describe WidgetsHelper do describe "#page_title" do it "includes the app name" do assign(:title, "This Page") helper.page_title.should eq("The App: This Page") end end end
- And
-
a file named "app/helpers/application_helper.rb" with:
module ApplicationHelper def app_name "The App" end end
- And
-
a file named "app/helpers/widgets_helper.rb" with:
module WidgetsHelper def page_title "#{app_name}: #{@title}" end end
