How can I test a help开发者_如何学运维er method living in app/helpers/application_helper.rb?
I have this code in my file test/unit/helpers/application_helper_test.rb
require 'test_helper'
class ApplicationHelperTest < ActionView::TestCase
test "category" do
assert categories_collection
end
end
But I get this error "NameError: undefined local variable or method `categories_collection'"
Try this:
require File.dirname(__FILE__) + '/../test_helper'
require 'application_helper'
class ApplicationHelperTest < Test::Unit::TestCase
include ApplicationHelper
def "category" do
assert categories_collection
end
end
