我想使用PhantomJS webdriver使用Selenium自動下載我的Google外帶數據。我開發了Selenium IDE Firefox插件中的操作,並使用npm包selenium-html-js-converter將測試用例的HTML輸出轉換爲JS。我的選擇是在Mozilla Firefox 45.0.2完美的工作,但如果使用轉換版本,它失敗,出現以下消息:硒與幻影JS失敗,但在火狐工作

Error: Failure in Selenium command "click("//tbody[@data-id=drive]/tr/td/div/", "")": [elementByXPath("//tbody[@data-id=drive]/tr/td/div/")] Error response status: 32, , InvalidSelector - Argument was an invalid selector (e.g. XPath/CSS). 

這是我想從這個外賣排除某些谷歌應用程序的一部分。我手動構建所有選擇器,因爲我不想依賴元素的類和ID,因爲這些元素是由某個構建工具自動生成的,並且可以隨時更改。

I read in this post引號可能是一個問題,但評估仍然失敗,沒有引號。我還嘗試將我的Firefox用戶代理更改爲PhantomJS正在使用的用戶代理(Mozilla/5.0 (Unknown; Linux x86_64) AppleWebKit/538.1 (KHTML, like Gecko) PhantomJS/2.1.1 Safari/538.1),以確保網站輸出相同,但仍能正常工作。但是我不知道如何更改Selenium中的用戶代理字符串。

我的硒核心代碼如下所示(我省略了自動生成的輔助功能,以保持它的整潔):

"use strict"; 
/* jslint node: true */ 

var assert = require('assert'); 

var browser, element, currentCommand = '', 
    options = { 
     timeout: 30000, 
     retries: 0, 
     screenshotFolder: 'screenshots/test_minimal_takeout_mobile_html', 
     baseUrl: 'https://accounts.google.com/' 
    }; 

module.exports = function testMinimalTakeoutMobileHtml(_browser, _options) { 

    browser = _browser; 
    var acceptNextAlert = true; 
    getRuntimeOptions(_options); 
    try { 
     currentCommand = 'open("/ServiceLogin?passive=1209600&continue=https%3A%2F%2Faccounts.google.com%2FManageAccount#identifier", "")'; 
     browser.get(addBaseUrl("/ServiceLogin?passive=1209600&continue=https%3A%2F%2Faccounts.google.com%2FManageAccount#identifier")); 

     currentCommand = 'type("id=Email", "[email protected]")'; 
     browser.elementById("Email").clear(); 
     browser.elementById("Email").sendKeys("[email protected]"); 

     currentCommand = 'click("id=next", "")'; 
     browser.elementById("next").click(); 

     currentCommand = 'uncheck("id=PersistentCookie", "")'; 
     if (browser.elementById("PersistentCookie").isSelected()) { 
      browser.elementById("PersistentCookie").click(); 
     }; 

     currentCommand = 'type("id=Passwd", "password")'; 
     browser.elementById("Passwd").clear(); 
     browser.elementById("Passwd").sendKeys("password"); 

     currentCommand = 'clickAndWait("id=signIn", "")'; 
     doAndWait(function() { 
      browser.elementById("signIn").click(); 
     }); 

     currentCommand = 'open("https://takeout.google.com/settings/takeout", "")'; 
     browser.get(addBaseUrl("https://takeout.google.com/settings/takeout")); 

     currentCommand = 'click("//tbody[@data-id=\'drive\']/tr/td/div/", "")'; 
     //<<< It fails here >>> 
     browser.elementByXPath("//tbody[@data-id=\'drive\']/tr/td/div/").click(); 

     currentCommand = 'click("//tbody[@data-id=\'chat\']/tr/td/div/", "")'; 
     browser.elementByXPath("//tbody[@data-id=\'chat\']/tr/td/div/").click(); 

     currentCommand = 'click("//tbody[@data-id=\'gmail\']/tr/td/div/", "")'; 
     browser.elementByXPath("//tbody[@data-id=\'gmail\']/tr/td/div/").click(); 

     currentCommand = 'click("//div[@data-state=\'1\']/div[2]/div[2]/div", "")'; 
     browser.elementByXPath("//div[@data-state=\'1\']/div[2]/div[2]/div").click(); 

     currentCommand = 'mouseDown("//div[@data-param=\'destination\']/div[2]/div[@role=\'presentation\']/div[2]", "")'; 
     browser.elementByXPath("//div[@data-param=\'destination\']/div[2]/div[@role=\'presentation\']/div[2]").mouseDown(); 

     currentCommand = 'mouseUp("//div[@data-param=\'destination\']/div[2]/div[@role=\'presentation\']/div[2]", "")'; 
     browser.elementByXPath("//div[@data-param=\'destination\']/div[2]/div[@role=\'presentation\']/div[2]").mouseUp(); 

     currentCommand = 'click("//div[@data-param=\'destination\']/div[2]/div[3]/div[@data-value=\'DRIVE\']", "")'; 
     browser.elementByXPath("//div[@data-param=\'destination\']/div[2]/div[3]/div[@data-value=\'DRIVE\']").click(); 

     currentCommand = 'click("//div[@data-state=\'2\']/div[2]/div[2]/div", "")'; 
     browser.elementByXPath("//div[@data-state=2]/div[2]/div[2]/div").click(); 

    } catch (e) { 
     var failedScreenShot = options.screenshotFolder + '/[email protected]' + currentCommand.replace(/\(.+/, '') + '.png'; 
     try { 
      createFolderPath(options.screenshotFolder); 
      browser.saveScreenshot(failedScreenShot); 
     } catch (e) { 
      e.message = 'Failure in Selenium command "' + currentCommand + '": ' + e.message + ' (Could not save screenshot after failure occured)'; 
      throw e; 
     } 
     e.message = 'Failure in Selenium command "' + currentCommand + '": ' + e.message + ' (Screenshot was saved to ' + failedScreenShot + ')'; 
     throw e; 
    } 

}; 

這是採取在測試失敗時顯示我正確的頁面截圖。

我正在使用NodeJS(5.10.1),PhantomJS(2.1.1)和Selenium(2.53.1)的最新穩定版本。

這裏怎麼回事?

需要引用每個屬性值做出的XPath的Valide:

browser.elementByXPath("//tbody[@data-id='drive']/tr/td/div/").click(); 
+0

屬性值與其中自動生成的代碼和我第一次嘗試它未能報價。但是,我將編輯我的答案以顯示正確的XPath。 – Noir

+1

XPath仍然不正確,您需要刪除報價前的轉義。 –
