Selenium IDE腳本在Selenium Webdriver中不起作用

Question

我創建了一些Selenium IDE腳本，然后將這些腳本導出到Java / Junit4 webdriver支持的腳本中，並且僅導出了簡單的webdriver類。 當我運行這些類時，測試用例唯一要做的就是打開正確的URL。 之后，作為登錄測試用例的測試用例根本無法找到userName字段。 我嘗試通過名稱或id都可以工作。 我什至嘗試添加一些方法來等待頁面加載（實際上加載沒有問題）； 我期望按名稱或ID部件至少可以工作，最后一個try塊使用我在網上找到的一種方法來繼續尋找userName字段，但是如果我解決了第一個try塊，則不需要surf。 我嘗試了一些在線資源，這些資源都在stackoverflow或其他論壇上，但有點令人困惑，因為來自IDE的簡單腳本無法輕松工作。

“ fuzoolPageCloseField”是一個加載並單擊腳本的窗口，它具有不同的名稱，但是我看到使用chrome defveloper工具時它具有不同的ID名稱，因此我在webdriver中使用它作為“ splash -something”原始名稱。在IDE中的運作方式。

堆棧跟蹤如下：

由於驅動程序超時，堆棧跟蹤在10秒間隔內帶有NoSuchElementException異常，最后一個異常在line 110(wait.until(new ExpectedCondition<Boolean>() {

ps我還運行了webdriver支持的類，它們也都在同一點失敗了（通過webdriver支持，我的意思是您實例化一個硒對象並使用它來進行測試，但是甚至： selenium.click("id=splash-32856-close-button;");不起作用，至少此si在驅動程序對象中起作用）

提前致謝

Answer 1

在網絡瀏覽器中查看HTML，以查明其為何不起作用。 我懷疑您會發現ID發生了變化，這就是Selenium無法找到它們的原因-因為它們已經不存在了。

Answer 2

我解決了我的問題。 IDE中的腳本可以在IDE中正常工作，在Java / Junit中將其導出時，語句類似於

      driver.findElement(By.id("userName")).clear();
      driver.findElement(By.id("userName")).sendKeys("742817");

但是，我手動調試了它，並確保自己進入了它。 我認為我有一個iframe，這就是驅動程序無法看到該元素的原因。

因此，我搜索了iFrame並成功了。

  WebElement iframeWebelement = driver.findElement(By.xpath("//html/body/form/...../tbody/tr/td/iframe"));
   System.out.println("iframeWebelement : Found ");

  driver.switchTo().frame(iframeWebelement);
   WebElement userNameField = driver.findElement(By.id("userName"));
    System.out.println("userName  : Found ");
        userNameField.sendKeys("myusername");
            System.out.println("userName  : entered data ");

這對我有用。 我不知道iFrame是我需要切換到的東西。

希望這對使用iFrame的人有所幫助。
