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

Answer: 
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

```

And of course [the rspec variant by Matt Darby](https://stackoverflow.com/a/441298/1152564) works in rails 3 too
This thread is kind of old, but I thought I'd reply with what I use:

```
# encoding: UTF-8

require 'spec_helper'

describe AuthHelper do

  include AuthHelper # has methods #login and #logout that modify the session

  describe "#login & #logout" do
    it "logs in & out a user" do
      user = User.new :username => "AnnOnymous"

      login user
      expect(session[:user]).to eq(user)

      logout
      expect(session[:user]).to be_nil
    end
  end

end

```
