org.openqa.selenium.SessionNotCreatedException：无法创建新会话。 （原始错误：请求新会话但其中一个正在进行中） [英] org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: Requested a new session but one was in progress)

问题描述

我正在使用Appium 1.4.8 for iOS。我已经使用xcode在模拟器中构建代码，并成功启动了服务器以及Appium Inspector。但是在运行我的代码时会抛出以下错误。

I am using Appium 1.4.8 for iOS . I have build the code in simulator using xcode and successfully able to launch the server as well as Appium Inspector. But while running my code it is throwing the below error.

我的功能是
@BeforeMethod
public void setUp（）抛出MalformedURLException {

My capabilities are @BeforeMethod public void setUp() throws MalformedURLException{

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("appium-version", "1.0");
capabilities.setCapability("platformName", "iOS");
capabilities.setCapability("platformVersion", "8.4");
capabilities.setCapability("deviceName", "iPad 2");
capabilities.setCapability("app", "/Users/arunhs/Desktop/AppiumReq/SRC/build/Debug-iphonesimulator/ComplianceWire.app");
driver = new AppiumDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);

}

Error is: 
FAILED CONFIGURATION: @BeforeMethod setUp

推荐答案

这是因为前一个会话未正确关闭，并且在测试中抛出异常时会发生这种情况。重新启动appium服务器并尝试它，它应该解决问题。

This happens because the previous session wasn't shutdown properly and it happens when there is exception thrown in your test. Restart the appium server and try it , it should resolve the issue.

或者如果您启动appium作为节点进程，您可以提供选项' - -session-override true'这可以避免这个问题

Alternatively if you starting appium as node process, you can give option '--session-override true' and this would avoid this problem
