Selenium & Webdriver 远程测试和多线程并发测试

Selenium & Webdriver 远程测试和多线程并发测试

  Selenium Webdriver自动化测试,初学者可以使用selenium ide录制脚本,然后生成java程序导入eclipse中调试运行!当然录制出来的东西回放不一定能成功,还需要手工去修改;selenium自动化测试工具,但是特殊情况下也可以用来测试性能;先来介绍一下selenium 如何启动远程pc上的浏览器进行测试!

启动远程pc浏览器之前,需要下载selenium-server-standalone-2.40.0.jar,

1、主机端cmd下运行命令:
java -jar selenium-server-standalone-2.40.0.jar -role hub

2、远程pc机cmd下运行命令:
java -jar selenium-server-standalone-2.40.0.jar -Dwebdriver.firefox.bin="E:\Mozilla Firefox\firefox.exe" -role  webdriver -hub http://10.30.12.110:4444/grid/register -browser browserName=firefox -port 7777

(Dwebdriver.firefox.bin="E:\Mozilla Firefox\firefox.exe是远程pc机浏览器安装路径;http://10.30.12.110:4444是主机地址和hub端口;节点端口7777不能和主机端口重复)

实例代码如下:

import java.io.File;
import java.net.URL;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.openqa.selenium.By;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.Platform;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.annotations.Test;

import net.sourceforge.htmlunit.corejs.javascript.tools.debugger.Main;

public class TestLogin  implements Runnable {  
    public static final SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSS");
@Test
    public void run() {
        System.out.println(Thread.currentThread().getId()+sf.format(new Date()));

DesiredCapabilities capability = DesiredCapabilities.firefox();
//      capability.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,true);
        //设置用来匹配node中要使用的浏览器
        capability.setBrowserName("firefox");
        capability.setVersion("24");
        capability.setPlatform(Platform.WINDOWS);
        
        WebDriver driver = null;
        String baseUrl = "http://XX.XX.XX.XX:9080/cas/login";
        //设置本地驱动,如果你实例化Driver的时候是"WebDriver driver = new InternetExplorerDriver(capability)"这种方式,就必须设置
        //System.setProperty("webdriver.ie.driver","D:\\IEDriverServer.exe");
        
        try{
            //本地启动浏览器
//            driver = new FirefoxDriver(capability);
            //远程启动浏览器
            driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),capability);
            System.out.println(Thread.currentThread().getId()+"访问网页开始时间:"+sf.format(new Date()));
            
              driver.get(baseUrl);
              //打开网页
              try {
                  //等待页面打开,超时设置10秒                  
                  WebElement loginAccount = new WebDriverWait(driver, 10).until(new ExpectedCondition<WebElement>() {
                      public WebElement apply(WebDriver d) {
                          return d.findElement(By.id("loginAccount"));
                   }
               });
                  if(null==loginAccount){
                    System.out.println(Thread.currentThread().getId()+" Timeout !!!");
                   driver.quit();
                   Thread.currentThread().interrupt();
                }else{
                    System.out.println(Thread.currentThread().getId()+"访问网页结束时间:"+sf.format(new Date()));
                    loginAccount.clear();                     
                   loginAccount.sendKeys("username");                    
                   WebElement loginPassword = driver.findElement(By.id("loginPassword"));
                   loginPassword.clear();
                   loginPassword.sendKeys("password");
                    WebElement area = driver.findElement(By.cssSelector("area"));
                   System.out.println(Thread.currentThread().getId()+"登录开始时间:"+sf.format(new Date()));
                   area.click();
                   try {
                    //等待登录成功,超时设置10秒                         
                    WebElement quxiao = new WebDriverWait(driver, 10).until(new ExpectedCondition<WebElement>() {
                        public WebElement apply(WebDriver d) {
                            return  d.findElement(By.xpath(".//*[@class='x-btn-mc']/em/button[text()='取消']"));
                           }
                       });
                    if(null==quxiao){
                            System.out.println(Thread.currentThread().getId()+" Loign  Timeout !!!");
                           driver.quit();
                           Thread.currentThread().interrupt();
                        }else{
                           System.out.println(Thread.currentThread().getId()+"登录成功时间:"+sf.format(new Date()));
                           System.out.println(Thread.currentThread().getId()+"点击取消时间:"+sf.format(new Date()));
                           quxiao.click();
                        
                       }
                } catch (Exception e) {
                       System.out.println(Thread.currentThread().getId()+" Loign Error !!!");
                       e.printStackTrace();
                       driver.quit();
                       Thread.currentThread().interrupt();
                   }
               }
              }
            catch (Exception e) {
                System.out.println(Thread.currentThread().getId()+" Visit Error !!!");
               e.printStackTrace();
               driver.quit();
               Thread.currentThread().interrupt();
            }
        }catch (Exception e) {
           e.printStackTrace();
           driver.quit();
        }finally{
            if(null!=driver){
                driver.quit();
            }
        }
    }

如果先要做远程多线程并发测试,将上面的代码new出了很多实例并且启动他们,启动selenium server也需要多加几个参数:

1、主机端cmd下运行命令:

java -jar selenium-server-standalone-2.40.0.jar -role hub -maxSession 40 -port 4444

(maxSession 设置最大连接数)

2、远程pc机cmd下运行命令:

java -jar selenium-server-standalone-2.40.0.jar -Dwebdriver.firefox.bin="E:\Mozilla Firefox\firefox.exe" -role node -hub http://127.0.0.1:4444/grid/register -maxSession 20 -browser "browserName=firefox,version=24,platform=WINDOWS,maxInstances=20" -port 5555

(maxInstances是同时运行浏览器的数量)

不过在我实际使用过程中火狐浏览器是无法同时实现并发的,但是IE浏览器就可以,所以需要把上面火狐的设置改成IE的就可以了!不到万不得已还是不建议使用这种方法进行性能测试!
