nosuchwindowexception selenium with phantomjs java

Question

我使用无头panthom浏览器使用phantomjs驱动程序与selenium自动化应用程序.(selenium java version 3.5.2和phantomjs.exe)

我有一个场景,我将填写表格并提交它,然后浏览器关闭,关闭浏览器后,我重新使用驱动程序引用来获取URL.当我使用带有selenium 2.47.0的firefox驱动程序时,它运行良好.

现在我切换到selenium phontamjsdriver和phantombrowser.这里当我调用driver.get(url);在浏览器关闭后,它抛出nosuchwindowexception,说窗口关闭或不活动.但是,相同的代码正在使用firefox驱动程序

例:

driver.get(url);// first time works  
submitForm(driver);//browser window gets closed.  
driver.get(url); 

最后一行是抛出异常:

nosuchwindowexception(selenium java with 3.5.2 version and phantomjs.exe). 

但与firefoxbrowser与selenium 2.4.7配合得很好.

Answer 1

首先，当您从Selenium v​​2.47.0迁移到Selenium v​​3.5.2时，值得一提的是，Selenium 3.x的可用性已经发生了很多变化。现在Selenium-WebDriver是W3C 推荐候选者，并且符合WebDriver W3C 编辑草案

没有这样的窗口异常

\n\n

NoSuchWindowException类扩展NotFoundException并在尝试时主要抛出：

\n\n

WebDriver.switchTo().window(String windowName);\n

现在，有关您的用例、相关HTML和代码块的更多详细信息将为我们提供更多关于出了什么问题的想法。也许 的定义submitForm(driver)是解决你的问题的关键。

最佳实践

\n\n

您可以遵循以下一些最佳实践来避免NoSuchWindowException：

\n\n

\n
• 始终将父窗口句柄存储在变量中，以便您可以根据通常需要遍历回父窗口。
\n
• 在调用之前，driver.switchTo().window(windowHandle);始终将WebDriverwait与ExpectedConditions方法结合使用numberOfWindowsToBe(int)。
\n
• 一旦您与ExpectedConditions方法结合调用driver.switchTo().window(windowHandle);诱导WebDriverWait来等待页面加载完成，以便在新打开的窗口上继续您的测试步骤。titleContains(java.lang.String title)
\n
• 要切换回父窗口，请使用先前存储的windowhandle。
\n

• 以下是演示窗口/选项卡处理的示例代码块：

  \n\n

  package demo;\n\nimport java.util.Set;\n\nimport org.openqa.selenium.JavascriptExecutor;\nimport org.openqa.selenium.WebDriver;\nimport org.openqa.selenium.firefox.FirefoxDriver;\nimport org.openqa.selenium.support.ui.ExpectedConditions;\nimport org.openqa.selenium.support.ui.WebDriverWait;\n\npublic class WINDOW_HANDLE_ITERATE_Firefox \n{\n    public static void main(String[] args) throws Exception \n    {\n        System.setProperty("webdriver.gecko.driver", "C:\\\\Utility\\\\BrowserDrivers\\\\geckodriver.exe");\n        WebDriver driver =  new FirefoxDriver();\n        driver.get("http://www.google.com");\n        String parent_window = driver.getWindowHandle();\n        System.out.println("Parent Window Handle is: "+driver.getWindowHandle());\n        System.out.println("Page Title is: "+driver.getTitle());\n        ((JavascriptExecutor) driver).executeScript("window.open(\'http://facebook.com/\');");\n        new WebDriverWait(driver,10).until(ExpectedConditions.numberOfWindowsToBe(2));\n        Set<String> allWindows_1 = driver.getWindowHandles();\n        System.out.println("Total Windows: "+allWindows_1.size());\n        for(String hand1:allWindows_1)\n        if(!parent_window.equals(hand1))\n        {\n            driver.switchTo().window(hand1);\n            new WebDriverWait(driver,10).until(ExpectedConditions.titleContains("Facebook"));\n            String first_child_window = driver.getWindowHandle();\n            System.out.println("First Child Window Handle is: "+first_child_window);\n            System.out.println("First Child Window Page Title is: "+driver.getTitle());\n            driver.close();\n        }\n        driver.switchTo().window(parent_window);\n        System.out.println("Current Window Handle is : "+driver.getWindowHandle()+ " which is same as "+parent_window +", which is the parent window handle" );\n        driver.quit();\n    }\n}\n
