     WebDriverWait wait = new WebDriverWait(driver,30); 

     wait.until(ExpectedConditions.elementToBeClickable(By.id("loginForm:submit"))); 

     driver.findElement(By.id("loginForm:user-name")).clear(); 
     driver.findElement(By.id("loginForm:user-name")).sendKeys("admin"); 

     driver.findElement(By.id("loginForm:user-password")).clear(); 
     driver.findElement(By.id("loginForm:user-password")).sendKeys("admin");

img id ändert sich ständig, das Skript macht scheitern. Beachten Sie, dass diese Ordner dynamisch erstellt werden, da in einer anderen Anwendung Daten erstellt werden.

Bitte stellen Sie eine Technik zur Verfügung, um das Element während jeder Iteration erfolgreich zu identifizieren.

Answer 1

Ich werde versuchen, einige Lösungen in diesem Fall

1. Verwenden FF WebDriver Element Locator https://addons.mozilla.org/en-US/firefox/addon/element-locator-for-webdriv/

2. Rekord Schritt/s mit Selenium IDE und dass das Element Kennung herauszufinden.

Hope diese hilft.

Answer 2

Es sieht aus wie Sie auf alle „Baumknoten“ auf der Seite zu klicken versuchen, so könnten Sie so etwas wie dies versuchen, wo Sie alle Knoten durch ihre Ur-Großeltern div finden:

List<WebElement> ygtvitems = enhancePreviewPage.getDriver().findElements(new By.ByCssSelector("div.ygtvitem")); 
    for (WebElement treeNode : ygtvitems) { 
     treeNode.click(); 
    }
