Java Selenium Pararel測試案例正在運行

Question

無法並行運行TC。 我設置了在testng.xml文件中運行的並行TC。 它打開4個瀏覽器實例，但測試用例失敗。 看起來它僅創建了一個瀏覽器會話實例（或類似的實例），因此它嘗試在一個實例中進行所有4個測試。

如何修改我的設置以成功並行運行TC？

我已經通過以下方式設置了驅動程序：

package MainSettings;

import Pages.StartPage;
//import TrackReporting.CaptureScreenShotOnFailureListener;
import TrackReporting.LoggingEventListener;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.events.EventFiringWebDriver;
import org.openqa.selenium.support.events.WebDriverEventListener;
import org.testng.annotations.*;

/**
 * Created by serhii.kaihorodov on 1/4/2016.
 */
//@Listeners(CaptureScreenShotOnFailureListener.class)
public class Settings {
    protected static WebDriver driver;
    protected String baseURL = "https://www.ukr.net";
    private static final WebDriverEventListener eventListener = new LoggingEventListener();
    protected StartPage mainPage;

    @BeforeMethod
    public void setUp()
    {
        System.setProperty("webdriver.chrome.driver", "D:\\Programming\\Java Automation\\ukr.net_test_cases-master\\chromedriver.exe");
//        driver = new EventFiringWebDriver(new FirefoxDriver()).register(eventListener);
        driver = new EventFiringWebDriver(new ChromeDriver()).register(eventListener);
        getDriver().get(baseURL);
        mainPage = new StartPage();
        driver.manage().window().maximize();
    }

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

    public static WebDriver getDriver()
    {
        return driver;
    }
}

我的testng.xml文件如下：

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name="My_auto_test" verbose="2" parallel="methods" thread-count="4">

    <test name="ukr.net">
        <classes>
            <class name="TestCases.TestCases_block_1"/>
        </classes>
    </test>

</suite>

我的幾個測試用例是：

package TestCases;

import MainSettings.Settings;
import org.testng.annotations.Test;

import java.io.IOException;

/**

 */
public class TestCases_block_1
{
    public class TestCases extends Settings
    {
        @Test (priority=0)
        public void login()
        {
            mainPage.login("kay444415@ukr.net", "06011988");
        }

        @Test (priority=0)
        public void sinoptik_link_is_present1()
        {
            mainPage.login("kay444415@ukr.net", "06011988").sinoptik_link_is_present();
        }

        @Test (priority=0)
        public void autosale_link_is_present1()
        {
            mainPage.login("kay444415@ukr.net", "06011988").autosale_link_is_present();
        }
  }

考慮使用線程安全變量，也許所有線程都使用相同的WebDriver實例進行所有測試，這就是崩潰的原因。 嘗試像這樣聲明變量：

在您的父類中，您應該有類似這樣的內容，以便您可以存儲WebDriver的多個實例

private Map<String, ThreadLocal> drivers = new HashMap<String, ThreadLocal>(); 

然后在TestCase類中，您應該有一種安全的方法來存儲WebDriver對象（java.lang.ThreadLocal為我們提供了WebDriver的線程安全包裝器。）

ThreadLocal<WebDriver> threadedDriver = new ThreadLocal<WebDriver>();
threadedDriver.set(/* method returning instance of WebDriver*/);

drivers.put(testName, threadedDriver); //so it can be saved in memory
WebDriver driver = drivers.get(testName).get(); //this is how you get the object for regular use

希望能幫助到你！
