Issue in acceptance test while redirecting to another page

Question

I am writing an acceptance test to check on clicking a button it gets redirected to another page(carts page), but I am getting an error while trying to do the same.

my code is:-

gift_cards_controller.rb

class GiftCardsController < ApplicationController
  before_filter :get_order_and_shipment, only: [:create]

  def create
    super do |format|
      if resource.errors.messages.any?
        format.html { render :new }
      else
        format.html { redirect_to carts_path }
      end
    end
  end
end

acceptance spec :-

gift_card_spec.rb

require 'spec_helper'

include Warden::Test::Helpers
Warden.test_mode!

describe 'Gift Card', type: :feature do
  before(:all) do
    Address.delete_all
  end

  it 'redirects to cart page' do
    user    = create(:user)
    login_as(user, scope: :user)
    address = create(:address, name: 'ABC',
                      street: 'PQR',
                      postal_code: '12345',
                      state_or_region: 'XYZ',
                      phone_number: '123-456-7890',
                      city: 'LMN',
                      user: user)

    add_str = 'ABC, PQR, LMN, XYZ, 12345'
    visit new_gift_card_path
    page.should_not have_content('Please add address before creating a gift card')
    page.should have_button('create gift card')
    fill_in 'gift_card_name',    with: 'Gift Card'
    fill_in 'gift_card_value',   with: 1000.99
    fill_in 'gift_card_message', with: "This is A Gift Card"
    option = first('#gift_card_address_list option').text
    expect(option).to eq(add_str)

    click_button 'create gift card'
    expect(page.current_url).to eq(carts_url)
    page.should have_content('ORDER SUMMARY')
  end
end

error:-

Gift Card
  redirects to cart page (FAILED - 1)

Failures:

  1) Gift Card redirects to cart page
     Failure/Error: expect(page.current_url).to eq(carts_url)

       expected: "http://www.example.com/cart"
            got: "http://www.example.com/gift_cards/new?gift_card[code]=75C4FC&gift_card[name]=Gift+Card&gift_card[value]=1000.99&gift_card[message]=This+is+A+Gift+Card&commit=create+gift+card"

[Edit]

On execution of click_button 'create gift card' line in the rspec, the control does not enter the create method in the controller. Because of which I am unable to check resourse.errors.messages.any?

            = f.input :code,input_html: {value: GiftCard.generate_code}, required: true
            = f.input :name,  label: 'Gift Card Name/Caption', required: false
            = f.input :value, label: 'Amount'
            = f.input :address_list, collection: current_user.addresses,
              label_method: :get_address_string, include_blank: false
            = f.input :message, as: :text, required: false

Answer 1

Seems your form is incorrect.

= simple_form_for :gift_card, url: gift_cards_path, method: :post do |f|
  %form
    %fieldset
      .form-inputs

1. remove the %form element
2. Use REST convention simple_form_for @gift_card do |f|

Answer 2

Based on the controller code you shared, it appears that either it's failing your before_filter or resource.errors.messages.any? was truthy and you rendered the new view rather than redirecting to carts_path. Without any other code, there's not much else to tell.
