@kovid，嗨。
让我们尝试逐步调试它：
1) 更新 selenium server 到最新版本
2) 确保您也使用 latest chromedriver
您能否也分享一下 testng.XML 套件的组织方式并分享您正在尝试执行的测试代码？
从我看到的异常来看 - 它试图访问浏览器实例，但由于某种原因无法访问。
可能被称为
driver.close();
要么
driver.quit(); 代码中的某处。
关于 testNG 配置 - 您可以查看 framework specs and/or example 表示测试套件的组织方式。
希望对您有所帮助，

==============
UPD 2019/03/02
除了上面提供的显式版本控制 @debanjanB ^^ 之外，我建议通过以下方式重新编写代码：
改进 #1
驱动程序初始化（我已经将此方法与适当的配置分开；我个人使用的是 selenium GRID ，但您可以继续使用您在代码中使用的 Chromedriver，我认为这是一个习惯问题）：
public static WebDriver driverSetUp(WebDriver driver) throws MalformedURLException {
ChromeOptions options = new ChromeOptions();
options.addArguments("-incognito");
DesiredCapabilities capability = DesiredCapabilities.chrome();
capability.setCapability(ChromeOptions.CAPABILITY, options);
//System.setProperty("webdriver.chrome.driver", System.getProperty("user.home")+"/Documents/:Proj_folder:/chromedriver");
System.setProperty("webdriver.chrome.driver", "chromedriver.exe");
capability.setBrowserName("chrome");
capability.setCapability("nativeEvents", true);
LoggingPreferences logs = new LoggingPreferences();
//Javascript console logs from the browser
logs.enable(LogType.BROWSER, Level.WARNING);
logs.enable(LogType.PERFORMANCE, Level.ALL);
capability.setCapability(CapabilityType.LOGGING_PREFS, logs);
String webDriverURL = "http://" + environmentData.getHubIP() + ":" + environmentData.getHubPort() + "/wd/hub";
log.info("creating driver instance on the URL :#### " + webDriverURL);
driver = new RemoteWebDriver(new URL(webDriverURL), capability);
driver.manage().window().maximize();
return driver;}
public static WebDriver driverInit(WebDriver driver, String startingUrl) throws MalformedURLException {
driver = DriverInit.driverSetUp(driver);
driver.get(startingUrl);
return driver;
}
并且如果您需要执行驱动程序重启操作 - 您可以使用包含在 try-catch 块中的 driver.close() 驱动程序初始化
public static WebDriver driverRestart(WebDriver driver, String startingUrl) throws MalformedURLException {
try {
driver.close();
} catch (WebDriverException e) {
log.error("#### oops, seems driver instance have been already closed. Doing re-initialization right now!", e.getMessage(), e);
}
return driverInit(driver, startingUrl);
}
所以 AfterMethod 看起来像（请添加 'alwaysRun=true' 标志）：
@AfterMethod(alwaysRun = true)
public void closeDriverInstance() {
try {
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File(
String.format("c:\SeleniumScreenshots\%s.jpg", count)));
driver.close();
} catch (Exception e) {
log.info(" oops, it seems that driver instance have been already closed.");
}
}
改进 #2
请稍微修改testng XML（请在suite标签中明确添加parallel="false"标签）：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="CustomerPortalTestSuite-SIT2" parallel="false" thread-count="5" verbose="8">
<test name="CustomerPortalTestExecution">
<classes>
<class name="testclasses.CustomerPortalSupportTest"/>
<class name="testclasses.CustomerPortalAccountTest"/>
<class name="testclasses.CustomerPortalBillingTest"/>
<class name="testclasses.CustomerPortalHomeTest"/>
</classes>
</test> <!-- Test -->
</suite> <!-- Suite -->
改进 #3（假设）
如果那没有帮助。根据经验，如果对于某些测试 chrome 实例启动并多次关闭并重新启动 - 你可能仍然有一堆
chromedriver.exe 进程（挂在您的系统中并阻止新的 chrome 驱动程序处理启动）
所以如果你发现你有很多进程，要在 WIN 中杀死它们 - 你可以调用命令：
Taskkill /T /F /IM chromedriver.exe
所以考虑到你 'kill' 每次你的 chrome 在每个测试方法之后，你还可以在方法之后杀死任何 chrome 驱动程序进程（解释 here 如何执行包裹在 java 代码中的 cmd）。
希望最终有所帮助:)
问候，

这个错误信息...
org.openqa.selenium.WebDriverException: Timed out waiting for driver server to start.
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03'
System info: host: 'PDC2LAP-7173253', ip: '10.170.10.178', os.name: 'Windows 10', os.arch: 'amd64', os.version: '10.0', java.version: '1.8.0_162'
Driver info: driver.version: ChromeDriver
...暗示 ChromeDriver 无法与 WebElement 交互。
您的主要问题是您使用的二进制文件版本之间不兼容，如下所示：
尽管您提到了使用：
- Java版本为java版本“1.8.0_201”
- ChromeDriver 2.43.600210
Tracelogs 说：
java.version: '1.8.0_162'
由于您使用的是 Selenium v3.141.59 组件不兼容。
解决方案
- 将JDK升级到最近的水平JDK 8u201。
- 将 ChromeDriver 升级到当前 ChromeDriver v2.46 级别。
- 保持Chrome版本在Chromev71-73[=47=之间] 水平。 (as per ChromeDriver v2.46 release notes)

所以如果你发现你有很多进程，要在 WIN 中杀死它们 - 你可以调用命令：
Taskkill /T /F /IM chromedriver.exe
所以考虑到你 'kill' 每次你的 chrome 在每个测试方法之后，你还可以在方法之后杀死任何 chrome 驱动程序进程（解释 here 如何执行包裹在 java 代码中的 cmd）。
希望最终有所帮助:) 问候， 尤金
这个错误信息...
org.openqa.selenium.WebDriverException: Timed out waiting for driver server to start.
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:17:03'
System info: host: 'PDC2LAP-7173253', ip: '10.170.10.178', os.name: 'Windows 10', os.arch: 'amd64', os.version: '10.0', java.version: '1.8.0_162'
Driver info: driver.version: ChromeDriver
...暗示 ChromeDriver 无法与 WebElement 交互。
您的主要问题是您使用的二进制文件版本之间不兼容，如下所示：
尽管您提到了使用：
- Java版本为java版本“1.8.0_201”
- ChromeDriver 2.43.600210
Tracelogs 说：
java.version: '1.8.0_162'
由于您使用的是 Selenium v3.141.59 组件不兼容。
解决方案
- 将JDK升级到最近的水平JDK 8u201。
- 将 ChromeDriver 升级到当前 ChromeDriver v2.46 级别。
- 保持Chrome版本在Chromev71-73[=47=之间] 水平。 (as per ChromeDriver v2.46 release notes)
