Rails- Testing Devise. reset password.Opening link in mail

I'm trying to test the devise feature for reseting a password, but I'm having some issues trying to test the link in the mail and visiting the page that is linked to.

I've tried unsuccessfully 2 ways to do it:

1)

scenario "User resets his password" do
  user2 = FactoryGirl.create(
  :user, reset_password_token: "new_password",
)

  visit new_user_password_path
  fill_in "Email", with: user2.email
  click_on "Send me reset password instructions"

  open_email(user2.email)
  click_first_link_in_email
  expect(page).to have_content("Reset your password")

end

If I do this I get the error:

Failure/Error: click_first_link_in_email

 ActionController::RoutingError:
   No route matches [GET] "/1999/xhtml'"

2)

scenario "User resets his password" do
  user2 = FactoryGirl.create( :user, reset_password_token: "new_password" )
  visit edit_user_password_path(reset_password_token:   
  expect(page).to have_content("Reset your password")
  end

If I do this it takes me to the initial page saying:

  "You can't access this page without coming from a password reset email"
