Capybara sign in/up helpers for use with Cucumber. Uses FactoryGirl to get sign up attributes, and to create a user for signing in.

module SignInHelpers
  def sign_up_as(user_type, form_params={})
    attributes = FactoryGirl.attributes_for(user_type).merge(form_params)
    destory_user(attributes[:email])

    within("#new_user") do
      fill_in "Name", :with => attributes[:name]
      fill_in "Email", :with => attributes[:email]
      fill_in "Password", :with => attributes[:password]
      fill_in "Password confirmation", :with => attributes[:password_confirmation]
    end
    click_button "Sign up"
    # return attributes[:email]
  end

    user = FactoryGirl.create(user_type, create_params)

    visit '/'
    fill_in "Username or Email", :with => form_params[:email] || user.email
    fill_in "Password", :with => form_params[:password] || user.password
    click_button "Sign in"

    sign_in_as(:user, params, email: "[email protected]")
  end

  def destory_user(email)
    user = User.where(email: email).first
    user.destroy unless user.nil?
