执行黄瓜时未定义的方法

Question

我写了一个黄瓜场景，步骤如下

Scenario: Validate in orders list the order status "Order Creates"
  When I click on the orders button
  And the order "14103795" is visible  
  # Then I can see the screen with the list of orders
  Then I can see the order status "Order Created", the message "Order successfully created", the order date "XXXX", the deliver date "XXXX" or the cancellation date "XXXX".

当我运行 .feature 文件时，它会执行，但是当文件完成运行:

时出现以下错误

undefined method `last' for #<String:0x007ffdba07f5e8> (NoMethodError)

而且，最后一步没有创建步骤骨架。

有人可以帮我解决这个问题吗？

这是步骤定义

When(/^I click on the orders button$/) do
    @orders = Orders.new
    @orders.click_orders
end

When(/^the order "([^"]*)" is visible$/) do |order|
    @orders.locateOrders(order)
end

这是我创建的页面对象中的类

def click_orders
    click_link('Pedidos')
    sleep(4)
end

def locateOrders(order)
    exists = false
    while exists == false
        if page.has_content?(order)
            exists=true
            @order_num=order
            puts 'exists'
        elsif page.has_content?(order) == false
            if page.has_content?("Carregar mais pedidos")
                click_button("Carregar mais pedidos")
                sleep(5)
            else
                fail(ArgumentError.new('Pedido não encontrado'))
            end
        end
    end 
end


def order_verify(order_status)
    sleep(3)
    counter = page.all(:xpath, '//*[@id="sh-content"]/div[1]/div[2]/div').count
    for i in 1..counter.to_i
        puts i
        within(:xpath, '//*[@id="sh-content"]/div[1]/div[2]/div['+i.to_s+']/div'){
            @card_order = find(:xpath, '//*[@id="sh-content"]/div[1]/div[2]/div['+i.to_s+']/div/div[1]/div[1]/span[2]').text
            puts @card_order
        }
        if @card_order == @order_num
            within(:xpath, '//*[@id="sh-content"]/div[1]/div[2]/div['+i.to_s+']/div'){


            }
        end
    end
end

最后一步，将调用 order_verify 方法，当我运行场景时没有生成骨架。

这是我的 env.rb 文件

require 'selenium/webdriver'
require 'rubygems'
require 'rspec'
require 'json'
require 'capybara/cucumber'



include Capybara::DSL
Capybara.default_driver = :chrome
Capybara.register_driver :chrome do |app|
Capybara::Selenium::Driver.new(app, :browser => :chrome)
end

Capybara.default_wait_time = 2

Answer 1

解决了。显然这是 cucumber 版本 2.0.2 的问题。

我刚刚卸载它并安装了 2.0.0 版使用 cucumber-core 1.1.3 并且错误不再发生。它还生成了步骤骨架。

Answer 2

如果您想同时使用最新的 Cucumber 2.0.2 和 capybara 2.5.0，请对您的 'env.rb' 文件进行以下更改。

替换此行：

 include Capybara::DSL

与：

World(Capybara::DSL)

为什么要使用 World()？：只是为了确保您不会篡改全局命名空间，但仍然可以在整个范围内使用该模块的所有功能。

对 env.rb 文件

中的所有 'include' 语句重复此操作

例如Capybara::RSpecMatchers、Test::Unit::Assertions、等等

希望这能解决您的问题，祝您好运！
