Question

我想将EventFiringWebDriver与RemoteWebDriver一起使用，因为我们正在使用硒网格，对于WebDriver，我的代码可以正常工作，但是当我尝试将EventFiringWebDriver转换为RemoteWebDriver时，运行时出现异常。

java.lang.ClassCastException: org.openqa.selenium.support.events.EventFiringWebDriver cannot be cast to org.openqa.selenium.remote.RemoteWebDriver

请帮助。

Answer 1

EventFiringWebDriver不是RemoteWebDriver的子类，因此您不能直接对其进行强制转换。在极少数情况下，您可能需要直接使用RemoteWebDriver，但是如果您需要事件触发包装程序正在使用的驱动程序实例，则可以执行以下操作：

// Note: Assume eventDriver is a valid EventFiringWebDriver instance
// Further note: Yes, it's possible to consolidate the below into fewer lines,
// but each step is shown here for clarity.
WrapsDriver wrapperAccess = (WrapsDriver)eventDriver;
WebDriver driver = wrapperAccess.getWrappedDriver();

// If you really, really need a RemoteWebDriver instance here, you can do this
RemoteWebDriver remoteDriver = (RemoteWebDriver)driver;

Answer 2

Sometimes we need concrete implementation, for example:

To have sessionID : ((RemoteWebDriver) webdriver).getSessionId()
To upload a file : ((RemoteWebDriver) webdriver).setFileDetector()

Answer 3

尝试

 ((RemoteWebDriver) ((EventFiringWebDriver) this.browserContext.getDriver()).getWrappedDriver());

Answer 4

对我有用（kotlin）

val driver = (getWebDriver() as EventFiringWebDriver).wrappedDriver as RemoteWebDriver
val sessionId = driver.sessionId.toString()

注意：我添加了类似的监听器

@BeforeEach
    fun beforeEach() {
        WebDriverRunner.addListener(Highlighter())
    }

将EventFiringWebDriver与RemoteWQebDriver结合使用
