You just describe the helper module and call the helper method like
you'd do in the views:
require File.dirname(__FILE__) + '/../spec_helper'
describe ApplicationHelper do
describe "breadcrumbs" do
describe "when breadcrumbs empty" do
it "should show nothing" do
breadcrumbs.should == ""
end
end
end
end

Something like this:
require File.dirname(__FILE__) + '/../spec_helper'
describe ApplicationHelper do
describe "keycase" do
describe "when no dots" do
before(:each) do
@value = "IBM"
end
it "should convert to lowercase" do
keycase(@value).should == "Ibm"
end
end
end
end
And so on.
