運行Java Selenium Pararel測試用例

Question

無法並行運行TC。我在testng.xml文件中設置了並行TC。它打開4個瀏覽器實例，但測試用例失敗。看起來它只創建了一個瀏覽器會話實例（或類似的東西），所以它試圖在一個實例中完成所有4個測試。

如何修改我的設置以並行運行TCs？

我已經設置了驅動程序以下列方式：

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>

我的幾個測試案例有：

package TestCases; 

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

import java.io.IOException; 

/** 
* Created by serhii.kaihorodov on 1/4/2016. 
*/ 
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(); 
     } 
    } 

Answer 1

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，這就是爲什麼崩潰。 嘗試聲明的變量是這樣的：

在你的父類，你應該有這樣的事情，所以你可以存儲的webdriver

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

幾個實例然後在TestCase類，你應該有一個安全的方式來存儲該物體的webdriver（java.lang.ThreadLocal中爲我們提供了一個的webdriver線程安全包裝。）

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 

希望它能幫助！
