Question

我正在使用带有testng的selenium网格进行分布式测试。我想在chrome和IE浏览器上运行远程机器上的测试。但是测试在这两个浏览器上都失败了。在Firefox上运行测试时，运行成功。

以下是用于初始化浏览器的代码：

DesiredCapabilities cap = new DesiredCapabilities();
cap.setBrowserName("chrome");
cap.setPlatform(Platform.WINDOWS);
driver = new RemoteWebDriver(new URL(URL),cap);
driver.get(myURL);

浏览器已成功初始化。找到元素和发送键时测试失败。找到元素的代码是：

driver.findElement(By.xpath(Xpath_Username)).sendKeys("abc");

我使用我的机器作为集线器而另一台机器作为节点。使用以下命令将节点连接到集线器：

java -jar selenium-server-standalone-2.47.1.jar -role webdriver -hub http://*myip*:4444/grid/register -port 8989 -browser browserName="chrome",version=ANY,platform=VISTA,maxInstances=5 -Dwebdriver.chrome.driver=D:\chromedriver.exe -browser browserName="internet explorer",version=ANY,platform=VISTA,maxInstances=2 -Dwebdriver.ie.driver=D:\IEDriverServer.exe

我正在不同的机器和浏览器上使用testng并行执行测试。测试的输出：

请提供任何解决方案。

Answer 1

通过添加以下代码解决了这个问题：

cap.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);

此外，必须在Internet Explorer中启用保护模式，并且所有区域都应该相同。

Answer 2

element = findElement（By.xpath（“// * input [@ id ='login'”））;

Selenium测试在远程机器上失败，因为chrome和驱动程序
