在 driver=new ChromeDriver(); 行获取 "InvocationTargetException" 异常；

Question

我正在打开 Chrome 浏览器，并获得了例外 "InvocationTargetException"。几天前代码是运行。这是我的代码

System.setProperty("webdriver.chrome.driver","D:\Automation\chromedriver_win32\chromedriver.exe");
driver=new ChromeDriver();

在 "driver=new ChromeDriver();" 行，我收到 "InvocationTargetException" 异常

Answer 1

InvocationTargetException

InvocationTargetException is a checked exception that wraps an exception thrown by an invoked method or constructor. It is an extra level of abstraction by calling the method with reflection. The reflection layer wraps any exception in an InvocationTargetException. The "target exception" that is provided at construction time and accessed via the getTargetException() method is now known as the cause, and may be accessed via the Throwable.getCause()方法，以及前面提到的"legacy method."

解决方案

最好的方法是解包 InvocationTargetException 中的原因以获得原始异常。

try {

        System.setProperty("webdriver.chrome.driver","D:\Automation\chromedriver_win32\chromedriver.exe");
        WebDriver driver=new ChromeDriver();

} catch (InvocationTargetException e) {
        // the real cause
        e.getCause().printStackTrace();

} catch (Exception e) {
        // generic exception handling
        e.printStackTrace();
}

最佳实践

按照最佳做法遵循以下准则：

将Chrome驱动程序升级到当前ChromeDriver v74.0.3729.6级别。
将 Chrome 版本保持在 Chrome v74 级别。 (as per ChromeDriver v74.0.3729.6 release notes)
以 非 root 用户身份执行您的 @Test。
始终在 tearDown(){} 方法中调用 driver.quit() 以优雅地关闭和销毁 WebDriver 和 Web Client 实例.
