ExecuteException：进程在ChromeDriver Chrome Selenium和TestNG Suite出现错误时退出

Question

当我通过TestNG xml执行TestNG套件时，我观察到以下错误。

测试最初在10-12个测试中顺利运行，但后来失败，出现上述错误消息。我希望这是一些问题与配置版本，但我不能找到它。

@BeforeMethod
public void initializetest() {
        System.setProperty("webdriver.chrome.driver", "C:\\Downloads\\ChromeDriverLatest\\chromedriver.exe");
        driver =new ChromeDriver();
        wait = new WebDriverWait(driver,10);

    }

    @AfterMethod
    public void endTest() throws IOException, Exception {
        File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
            FileUtils.copyFile(scrFile, new File("c:\\SeleniumScreenshots\\" + count +".jpg"));
            count++;
        Thread.sleep(5000);

        driver=null;
    }

下面的测试类示例：

@DataProvider(name="editAccDetails")
    public Object[][] logincreds(){
        Object[][] data = new Object[1][2];
        data[0][0] = "test";
        data[0][1] = "test";
        return data;
    }


    @Test(priority=1, dataProvider="editAccDetails")
    public void Details(String UsernameDP, String PasswordDP) throws Exception {
            Login TS1 = new Login(driver,wait);
            TS1.test(UsernameDP, PasswordDP);
            HomePage TS2 = new HomePage(driver,wait);
            TS2.test();
            AccountPages TS3 = new AccountPages(driver,wait);
            TS3.Details();

    }

Answer 1

@科维德，嗨。让我们尝试一步一步地调试它：

>

1)将selenium server更新至最新版本

2）确保您也使用最新的chromedriver

希望对你有帮助，尊敬的尤金

====================UPD 2019/03/02除了上面提供的明确版本控制@debanjanb外^^,我建议以以下方式重新编写代码：

改进#1驱动程序init（我已经用适当的配置分离了这个方法；我个人使用的是selenium GRID，但您可以继续使用代码中使用的Chromedriver，我认为这是习惯问题）：

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;
}

如果您需要执行驱动程序重新启动操作-您可以使用驱动程序init，并将driver.close()包装在try-catch块中

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

<?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 --> 

因此，如果您发现有许多进程，要在WIN中杀死它们，您可以调用以下命令：

Taskkill /T /F /IM chromedriver.exe

因此，考虑到在每个测试方法之后您每次都要“杀死”chrome进程，您可能还会在after方法中杀死任何chromedriver进程（这里解释了如何执行封装在java代码中的cmd）。

希望最后能有所帮助：）问候你，尤金
