下拉菜單並切換到Selenium Webdriver中的新窗口在Firefox中不起作用

[英]Dropdown Menu and switch to new Window in Selenium Webdriver not working in Firefox

 原文  2014-12-17 07:08:30  3   1    java/ javascript/ eclipse/ firefox/ selenium

問題描述

我試圖通過我在www.salesforce.com上的開發人員登錄信息來自動化一些網頁，例如創建案例，創建客戶和聯系人。 我正在將Mozilla Firefox 34.0.5以及Eclipse Luna和Java用於Selenium WebDriver自動化。 我還使用JExcel API從硬盤中的excel文件讀取數據。 系統規格為Windows7 Ultimate 32位。

我的自動化代碼在Google Chrome上運行正常，但是在Firefox中，網頁上的某些字段（例如下拉菜單框，彈出窗口和將控件切換到新的彈出窗口）不起作用。 我沒有找到任何解決此問題的方法。 我無法理解硒命令失敗的原因：“ selectByVisibleText（String）”。

  1. 顯示下拉菜單列表，並突出顯示指定的選項，但隨后單擊/選擇操作被中止，並選擇了默認值。

  2. 在彈出窗口中，硒命令：“ driver.switchTo（）。window（windowhandle）”不起作用。 將打開新的彈出窗口並生成了窗口句柄，但顯示的錯誤是“無法找到窗口{window Handle String}”。

我無法弄清楚為什么它無法通過窗口句柄找到該窗口並不能在firefox中切換到它（如果在其他瀏覽器中可以正常工作的原因）？

以下是我的完整代碼 

public class PoiExcelCase {

    WebDriver driver;
    FileInputStream fis;
    HSSFWorkbook wb;
    HSSFSheet sh;

    @BeforeTest
    public void login() throws BiffException, IOException

        driver = new FirefoxDriver();
        //System.setProperty("webdriver.chrome.driver", "D:/chromedriver_win32/chromedriver.exe");
        //driver = new ChromeDriver();

        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
        fis = new FileInputStream(new File("D:/Salesforce.xls"));
        wb = new HSSFWorkbook(fis);
        sh = wb.getSheet("Sheet1");
        driver.navigate().to("http://www.salesforce.com/in/?ir=1");
        driver.findElement(By.xpath(".//*[@id='button-login']")).click();
        driver.findElement(By.xpath(".//*[@id='username']")).sendKeys(sh.getRow(1).getCell(0).getStringCellValue());

請在線找到我的答案：

1-顯示下拉菜單列表，並且突出顯示了指定的選項，但是單擊/選擇操作被中止，並且選擇了默認值。

您首先單擊了下拉菜單，然后嘗試選擇不需要的項目。 只需創建"Select class"對象並使用selectByVisibleText("text to be selected")完成以下操作（ 僅摘錄自代碼，並根據需要進行了修改 ） 

        we = driver.findElement(By.xpath(".//*[@id='cas7']"));
        se = new Select(we);
        se.selectByVisibleText(sh.getRow(2).getCell(5).getStringCellValue());

2-在彈出窗口中，硒命令：“ driver.switchTo（）。window（windowhandle）”不起作用。 將打開新的彈出窗口並生成了窗口句柄，但顯示的錯誤是“無法找到窗口{window Handle String}”。

首先獲取主窗口句柄，然后單擊帶來新窗口句柄的元素，然后使用以下代碼切換到新窗口（ 同樣，我剛剛修改了代碼摘錄 ） 

        String mainwindow = driver.getWindowHandle();        
        driver.findElement(By.xpath(".//*[@id='cas3_lkwgt']/img")).click();//Assuming clicking on this element brings out the new window

        Set<String> s = driver.getWindowHandles(); 
        Iterator<String> ite = s.iterator(); 
        while(ite.hasNext()) 
        { 
            String popup = ite.next(); 
            if(!popup.equalsIgnoreCase(mainwindow)){ 
                driver.switchTo().window(popup); 
                break;
              }
        }
