java - 无法创建新的远程会话。所需功能 = Capabilities [{ie.ensureCleanSession=true}]，启动 IE 时所需的功能

Question

我已将 IE 驱动程序更新到 3.12.0.0，但它无法正常工作。我收到以下错误消息

代码：

DesiredCapabilities cap = new DesiredCapabilities();
cap.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);
System.setProperty("webdriver.ie.driver", "C:\\iedriver\\IEDriverServer.exe");
WebDriver driver = new InternetExplorerDriver(cap);
driver.manage().window().maximize();
driver.manage().deleteAllCookies();

来自控制台的错误消息

Unable to create new remote session. desired capabilities = Capabilities [{ie.ensureCleanSession=true}], required capabilities = Capabilities [{}]

Answer 1

你快到了。您需要使用MutableCapabilities类中的方法merge()方法将DesiredCapabilities类型的对象合并到InternetExplorerOptions类型的对象中，并通过传递InternetExplorerOptions对象来启动WebDriver和WebClient实例，如下所示：

System.setProperty("webdriver.ie.driver", "C:\\iedriver\\IEDriverServer.exe");
DesiredCapabilities cap = DesiredCapabilities.internetExplorer();
cap.setCapability(InternetExplorerDriver.IE_ENSURE_CLEAN_SESSION, true);
InternetExplorerOptions options = new InternetExplorerOptions()
options.merge(cap);
WebDriver driver = new InternetExplorerDriver(options);
