IEDriver總是thows NoSuchElementException異常

Question

瀏覽器：IE11 IEDriver：IEDriverServer_x64_3.3.0 代碼片段：

public class DownloadinIE 
{ 
    long timeout = 1000; 
    public String classname = this.getClass().getSimpleName(); 
    String date = new SimpleDateFormat("yyyy_MM_dd_HH").format(Calendar.getInstance().getTime()).toString(); 
    String downloadPath = \\ur download path; 
    public WebDriver driver; 

    @BeforeMethod 
    public void setup() 
    { 
System.setProperty("webdriver.ie.driver","\\IEDriverServer.exe"); 
     driver = new InternetExplorerDriver(); 
    } 
    @Test 
    public void download() throws InterruptedException 
    { 
     driver.get("https://www.eclipse.org/downloads/?"); 
     Thread.sleep(10000); 
     driver.findElement(By.cssSelector("[title='64 bit Download']")).click(); 
     Thread.sleep(3000); 
     driver.findElement(By.cssSelector(".fa.fa-download")).click(); 
     Thread.sleep(3000); 
     BaseLibrary.verifyFileDownloaded(downloadPath); 
    } 
} 

錯誤信息：如果文件下載完畢

verifyFileDownloaded方法驗證。我的問題是驅動程序沒有從第一個元素單擊直接識別任何對象。此測試在Firefox和Chrome中運行良好。這裏有什麼問題？請提供您的建議。

我的應用程序需要在IE中測試以獲得類似的功能。這就是爲什麼我這樣試圖

Answer 1

請確保您的InternetExplorer =>互聯網選項=>安全所有被禁用或水平低。這幫助了我。
