I'm trying to build some unit tests for testing my Rails helpers, but I can never remember how to access them. Annoying. Suggestions?

推荐答案

在rails 3中，您可以执行此操作(实际上这是生成器创建的):

In rails 3 you can do this (and in fact it's what the generator creates):

require 'test_helper'

class YourHelperTest < ActionView::TestCase
  test "should work" do
    assert_equal "result", your_helper_method
  end
end

当然， Matt Darby的rspec变体也可以在Rails 3中使用

And of course the rspec variant by Matt Darby works in rails 3 too
