我如何在Ruby中使用硒？

Question

我用Firefox Selenium做了一些測試，然後將它導出到Ruby。儘管測試在Firefox中運行良好，但我在Ruby中運行相同的套件時遇到了問題。

我試圖運行他們有的示例程序之一，我也得到了同樣的連接拒絕錯誤。這是我嘗試運行google_test套件時遇到的錯誤。

tellingsen$ ruby google_test.rb

Answer 1

我在論壇上搜索了幾個小時並通過谷歌找到了它。

我需要做的是讓硒服務器運行它。我能夠從這個網站下載http://seleniumhq.org/download/（當前：Selenium RC 2010年2月23日1.0.3）。

從那裏我打開了一個新的終端，做

cd Downloads/selenium-remote-control-1.0.3/selenium-server-1.0.3 
java -jar selenium-server.jar 

然後跑到我的紅寶石生成的腳本與另一個終端窗口

ruby google_test.rb 

和它的工作！

Answer 2

這是硒的webdriver例如，對於簡單的谷歌搜索 另存爲google_search.rb

require "selenium-webdriver" 
require "test/unit" 

class GoogleSearch < Test::Unit::TestCase 
    def setup 
    @driver = Selenium::WebDriver.for :firefox 
    @base_url = "http://www.google.com/" 
    @driver.manage.timeouts.implicit_wait = 30 
    @verification_errors = [] 
    end 
    def teardown 
    @driver.quit 
    assert_equal [], @verification_errors 
    end 
    def test_google_search 
    @driver.get(@base_url) 
    @driver.find_element(:name, "q").clear 
    @driver.find_element(:name, "q").send_keys "Thiyagarajan Veluchamy" 
    @driver.find_element(:name, "btnK").click 
    end 
    def element_present?(how, what) 
    @driver.find_element(how, what) 
    true 
    rescue Selenium::WebDriver::Error::NoSuchElementError 
    false 
    end 
    def verify(&blk) 
    yield 
    rescue Test::Unit::AssertionFailedError => ex 
    @verification_errors << ex 
    end 
end 

$紅寶石google_search.rb

Answer 3

這裏是腳本的一個更簡單的版本：

require "selenium-webdriver" 

@driver = Selenium::WebDriver.for :chrome 
@base_url = "http://www.google.com/" 

@driver.get(@base_url) 
@driver.find_element(:name, "q").send_keys "Stack Overflow" 

@driver對象上的可用方法可在此處找到：http://selenium.googlecode.com/svn/trunk/docs/api/rb/Selenium/WebDriver/Driver.html

find_element可讓您訪問Element類。可以在這裏找到Element類的方法： http://selenium.googlecode.com/svn/trunk/docs/api/rb/Selenium/WebDriver/Element.html
