org.openqa.selenium.SessionNotCreatedException：无法创build新的会话。 （原始错误：请求新的会话，但正在进行中）
我正在使用Appium 1.4.8 for iOS。 我已经使用xcode在模拟器中构build了代码，并成功地启动了服务器以及Appium Inspector。 但是，当运行我的代码是抛出以下错误。
我的能力是@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 org.openqa.selenium.SessionNotCreatedException: A new session could not be created.

发生这种情况是因为之前的会话没有正常closures，而且在testing中出现exception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。
或者，如果将appium作为节点进程启动，则可以select'--session-override true' ，这样可以避免这个问题
以下是为我工作。 我正在通过连接Android设备进行testing。 请根据您的需要进行更改并申请，现在这个工作。
DesiredCapabilities capabilities = new DesiredCapabilities().android(); capabilities.setCapability("no",true); capabilities.setCapability("newCommandTimeout", 100000); capabilities.setCapability("noReset", true); capabilities.setCapability(CapabilityType.BROWSER_NAME, ""); capabilities.setCapability(CapabilityType.VERSION, "4.4.2"); capabilities.setCapability("deviceName", "Galaxy nexus"); capabilities.setCapability("app", application.getAbsolutePath()); capabilities.setCapability("automationName", "selendroid"); capabilities.setCapability("noRest", true); driver = new AndroidDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
如果在appium应用程序，然后selectOverride Existing Sessionscheckbox下的设置 –
在function中添加deviceName有帮助。 在日志中，我可以找出丢失的东西。
