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 Firefoxfirefox.exe" -role webdriver -hub http://10.30.12.110:4444/grid/register -browser browserName=firefox -port 7777
(Dwebdriver.firefox.bin="E:Mozilla Firefoxfirefox.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,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 Firefoxfirefox.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浏览器可以,所以需要把上面火狐的设置改成IE的可以了!不到万不得已还是不建议使用这种方法进行性能测试!
