Selenium grid2+ testng并发式 困惑

1. 启动selenium hub

2. 启动selenium node（假设有2 node）

清单1. testng.xml

清单2： TestDemo.java( Package name: server)

public class TestDemo {

public static WebDriver wd;

private static int sum = 0;

@BeforeClass

public void SetUp(){

long id = Thread.currentThread().getId();

System.out.println("Set Up: "+ Thread.currentThread().getStackTrace()[1].getMethodName()+", Thread# " + id);

}

@AfterClass

public void TearDown(){

long id = Thread.currentThread().getId();

System.out.println("Tear Down: "+ Thread.currentThread().getStackTrace()[1].getMethodName()+", Thread# " + id);

}

@BeforeTest

public void BeforeTest(){

long id = Thread.currentThread().getId();

System.out.println("Test Case: "+ Thread.currentThread().getStackTrace()[1].getMethodName()+", Thread# " + id);

}

@AfterTest

public void AfterTest(){

long id = Thread.currentThread().getId();

System.out.println("Test Case: "+ Thread.currentThread().getStackTrace()[1].getMethodName()+", Thread# " + id);

}

@Test(invocationCount = 15, threadPoolSize = 10)

@Parameters({"seleniumHost", "seleniumPost", "bs"})

public void test022222(String Host, String Port, String browser) throws MalformedURLException, InterruptedException, UnknownHostException{

sum ++;

System.out.println("sum = " + sum);

long id = Thread.currentThread().getId();

System.out.println("Test Case: "+ Thread.currentThread().getStackTrace()[1].getMethodName()+", Thread# " + id);

File file = new File("C:/Program Files (x86)/Internet Explorer/IEDriverServer.exe");

System.setProperty("webdriver.ie.driver", file.getAbsolutePath());

//String hubURL = "http://192.168.1.112:4444/wd/hub";

String hubURL ="http://" +Host + ":" +Port + "/wd/hub" ;

System.out.println( "hubURL = " + hubURL);

DesiredCapabilities aDesiredCap = new DesiredCapabilities();

aDesiredCap.setBrowserName("internet explorer");

aDesiredCap.setVersion("");

aDesiredCap.setPlatform(Platform.WINDOWS);

aDesiredCap.setCapability(InternetExplorerDriver.IGNORE_ZOOM_SETTING, true);

//wd = new InternetExplorerDriver();

wd = new RemoteWebDriver(new URL(hubURL),aDesiredCap);

wd.get("http://www.qq.com");

Thread.sleep(3000);

System.out.println(wd.getCurrentUrl());

wd.quit();

}

}

运行testng.xml

Consle output：

总结现象： case运行invocationCount 次数，最大并发数threadPoolSize ，

这15次，被随机分配到2 node上面运行，但是存在这样的问题： 其中node运行用例的时间很慢，网页请求响应很慢，几乎等不到相应。卡死状态

假设只有一个node，运行15次，响应正常，执行用例15次，正常结束，可是这不是我们想要的并发场景。

selenium grid2真的适合性能测试吗？我突然有这样的困惑？望有人赐教，谢谢。
