Selenium WebDriver RuntimeException：进程在10秒后拒绝死亡，并且无法执行任务：无法找到可执行文件：taskkill [英] Selenium WebDriver RuntimeException:Process refused to die after 10 seconds, and couldn't taskkill it: Unable to find executable for: taskkill

问题描述

  public class Second {
  private WebDriver driver;
  private boolean acceptNextAlert = true;
  private StringBuffer verificationErrors = new StringBuffer();

  @BeforeClass
  public void beforeClass() {
  driver = new FirefoxDriver();
  driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  driver.manage().window().maximize();
  }


 @Test
  public void testSecond() throws Exception {
  driver.get("url");
  System.out.println("test two");
  Thread.sleep(5000);

 }

 @AfterClass
 public void afterClass() throws Exception{
  driver.quit();
    String verificationErrorString = verificationErrors.toString();
    if (!"".equals(verificationErrorString)) {
      fail(verificationErrorString);
    }
 }
}

这是一个testNG测试案例在driver.quit（）中抛出Runtime Exception。
测试成功通过但测试完成后浏览器未关闭

Stack Trace：

This is a testNG test case which throws Runtime Exception at driver.quit(). test is passed successfully but browser is not closed after test completes
Stack Trace:

我已经将TcpTimedWaitDelay设为30秒。

I have given TcpTimedWaitDelay as 30 seconds.

推荐答案

taskkill是一个标准的Windows实用程序。 Selenium无法找到它的事实意味着环境变量PATH不包含包含标准系统实用程序的目录。对于现代Windows版本，它是C：\ Windows \ system32。

taskkill is a standard Windows utility. The fact that Selenium cannot find it means that the environment variable PATH does not include the directory that contains standard system utilities. It is C:\Windows\system32 for modern Windows versions.

将此目录添加到PATH变量（按照此说明修改PATH变量： http://www.computerhope.com/issues/ch000549.htm ）并重新启动运行Selenium脚本的控制台或IDE应用此环境变化。

Add this directory to the PATH variable (follow this instruction to modify the PATH variable: http://www.computerhope.com/issues/ch000549.htm) and restart the console or IDE where you run Selenium scripts to apply this environment change.
