并行测试线程获取孤立的 Selenium

Question

我的测试在我的虚拟机上执行。 Chrome首先加载，然后是IE。 IE 完成测试，但 Chrome 成为孤儿。我认为这与连接正确浏览器的线程有关。

我已经尝试了很多小时尝试使用 Selenium/TestNG 设置并行测试的不同方法，结果与我上面描述的相同。

我的目标是让两个浏览器都完成测试。你能帮我么。 请在下面找到我的代码。

public class BaseTestDirectory {
// -------Reference Variables-------------
// ----- Regression Test Cases -----
LoginLogoutPage objBELogin;
HomeNavigationPage obj_navigation;
DirectoryPage obj_directory;
// -------------------------------
protected static WebDriver driver;
protected ExtentTest test;// --parent test
ExtentReports report;
ExtentTest childTest;

@BeforeClass
 @Parameters(value={"browser"})
    public void setUp(String browser) throws InterruptedException, MalformedURLException {
    // --------Extent Report--------
    
    if(browser.equals("Chrome")){ 
        
            report = ExtentManager.getInstance();
            System.setProperty("webdriver.chrome.driver", "C:\\GRID\\chromedriver.exe");

            System.out.println(System.getenv("BUILD_NUMBER"));
            String env = System.getProperty("BUILD_NUMBER");
            
            if (env == null) {
                driver = new RemoteWebDriver(new URL(COMPLETE_NODE_URL), OptionsManager.getChromeOptions());
                driver.get(HOME_PAGE);
                driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
            } else {
                driver = new ChromeDriver();
                driver.get(HOME_PAGE);
                driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
                }
            }
    
    else if (browser.equals("IE")) {
                
                report = ExtentManager.getInstance_IE();
                System.setProperty("webdriver.ie.driver", "C:\\GRID\\IEDriverServer.exe");

                System.out.println(System.getenv("BUILD_NUMBER"));
                String env = System.getProperty("BUILD_NUMBER");
                
                driver = new RemoteWebDriver(new URL(COMPLETE_NODE_URL), OptionsManager.getInternetExplorerOptions());
                driver.get(HOME_PAGE);
                driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
                
            }
    
}

public class OptionsManager {

Answer 1

将 WebDriver 对象初始化为并行测试执行的线程本地：当您决定并行运行 selenium 的测试时，您的 Webdriver 对象应该是线程安全的，即单个对象可以同时与多个线程一起使用不会引起问题。

public class BaseTest {
   //Declare ThreadLocal Driver (ThreadLocalMap) for ThreadSafe Tests
    protected static ThreadLocal<RemoteWebDriver> driver = new ThreadLocal<>();
    public CapabilityFactory capabilityFactory = new CapabilityFactory();

@BeforeMethod
@Parameters(value={"browser"})
public void setup (String browser) throws MalformedURLException {
    //Set Browser to ThreadLocalMap
    driver.set(new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capabilityFactory.getCapabilities(browser)));
}

public WebDriver getDriver() {
    //Get driver from ThreadLocalMap
    return driver.get();
}

@AfterMethod
public void tearDown() {
    getDriver().quit();
}

@AfterClass void terminate () {
    //Remove the ThreadLocalMap element
    driver.remove();
}

}

尝试在下面给出的示例中设计您的基类 公共类 WebDriverFactory {

static WebDriver create(String type) throws IllegalAccessException{
    WebDriver driver;
    
    switch(type) {
      
    case "Firefox":
          driver = new FirefoxDriver();
          break;
    case "Chrome":
          driver = new ChromeDriver();
          break;
    default:
         throw new IllegalAccessException();
    }
    
    return driver;
}

}

 public class BaseClass extends WebDriverFactory  {

public static ThreadLocal<WebDriver> dr = new ThreadLocal<WebDriver>();

@Parameters("browser")
@BeforeMethod
public void beforemethod() throws IllegalAccessException{
    
    WebDriver driver = new WebDriverFactory().create(browser);
    setWebDriver(driver);
    
    
    getWebDriver().manage().window().maximize();
    getWebDriver().manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}


public void setWebDriver(WebDriver driver){
    dr.set(driver);
}


public WebDriver getWebDriver(){
    return dr.get();
}

@AfterMethod
public void aftermethod(){
    getWebDriver().quit();
    dr.set(null);
}

}
