Selenium WebDriver RuntimeException:Process refused to die after 10 seconds, and couldn't taskkill it: Unable to find executable for: taskkill
提问by Grishma Oswal
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);
}
}
}
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:
这是一个 testNG 测试用例，它在 driver.quit() 处抛出运行时异常。测试成功通过，但测试完成后浏览器没有关闭

I had the same runTimeException, running webdriver on IE 11 and using TestNG.
我有同样的runTimeException，在 IE 11 上运行 webdriver 并使用 TestNG。
As a workaround I used a try catchin the @AfterSuite and killed the background process :
作为一种解决方法，我try catch在@AfterSuite 中使用了 a并终止了后台进程：
public void closeBrowser()
{
try
{
driver.close();
Runtime.getRuntime().exec("taskkill /F /IM IEDriverServer.exe");
}
catch (Exception anException)
{
anException.printStackTrace();
}
}
Works as expected so far...
到目前为止按预期工作......

driver.quit();causes the problem. If you use driver.close();this exception will not be thrown, and the browser will be closed properly.
driver.quit();导致问题。如果使用driver.close();这个异常不会抛出，并且浏览器会正常关闭。

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.
taskkill 是一个标准的 Windows 实用程序。Selenium 找不到它的事实意味着环境变量 PATH 不包括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。
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.
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 以应用此环境更改。

this quit() problem only on MS IE. my workaround with IEDriver.exe and selenium remotewebdriver is:
这个退出（）问题仅在 MS IE 上。我使用 IEDriver.exe 和 selenium remotewebdriver 的解决方法是：
quit() //close tested window
quit() //quit ie browser
quit() //关闭测试窗口
quit() //退出ie浏览器

Adding to @Alexeianswer, as the path C:\Windows\system32is alreadyadded to Windows Path, restartingmy eclipse with Admin privilegesworked for me in Windows 10 OS.
添加到@Alexei答案，因为路径C:\Windows\system32是已经加入Windows Path，重新开始我的日食带Admin privileges在为我工作Windows 10 OS。
