Selenium Grid允许你在多台机器的多个浏览器上并行的进行测试，即分布式测试。
通常，以下两种情况会需要使用Selenium Grid：
- 通常多个浏览器的兼容性测试，即在不同浏览器或不同操作系统的浏览器中进行测试
-
测试用例较多时，可以通过分布式测试减少测试执行时间

1、下载selenium-server-standalone-3.11.0.jar
https://selenium-release.storage.googleapis.com/index.html?path=3.11/
2、启动hub
java -jar selenium-server-standalone-3.11.0.jar -role hub
3、启动node
java -Dwebdriver.chrome.driver="D:\\drivers\\chromedriver.exe" -Dwebdriver.ie.driver="D:\\drivers\\MicrosoftWebDriver.exe" -Dwebdriver.gecko.driver="D:\\drivers\\geckodriver.exe" -jar selenium-server-standalone-3.11.0.jar -role node -port 5555 -hub http://192.168.0.153:4444/grid/register
java -Dwebdriver.chrome.driver="D:\\drivers\\chromedriver.exe" -Dwebdriver.ie.driver="D:\\drivers\\MicrosoftWebDriver.exe" -Dwebdriver.gecko.driver="D:\\drivers\\geckodriver.exe" -jar selenium-server-standalone-3.11.0.jar -role node -port 5556 -hub http://192.168.0.153:4444/grid/register
java -Dwebdriver.chrome.driver="D:\\drivers\\chromedriver.exe" -Dwebdriver.ie.driver="D:\\drivers\\MicrosoftWebDriver.exe" -Dwebdriver.gecko.driver="D:\\drivers\\geckodriver.exe" -jar selenium-server-standalone-3.11.0.jar -role node -port 5557 -hub http://192.168.0.153:4444/grid/register

4、访问grid的console页面

5、testng.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>
<suite name="Suite" parallel="classes" thread-count="3">
<test name="allTest">
<classes>
<class name="com.yzc.mysystem.test.RemoteFirefoxTest"/>
<class name="com.yzc.mysystem.test.RemoteChromeTest"/>
<class name="com.yzc.mysystem.test.RemoteInternetExplorerTest"/>
</classes>
</test>
</suite>
6、远程操纵火狐浏览器的Java代码
package com.yzc.mysystem.test;
import static org.testng.Assert.assertEquals;
import java.net.URL;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.Test;
public class RemoteFirefoxTest {
@Test
public void f() throws Exception {
DesiredCapabilities capability = DesiredCapabilities.firefox();
capability.setBrowserName("firefox");
capability.setPlatform(Platform.WINDOWS);
//capability.setVersion("61");
//System.setProperty("webdriver.gecko.driver","D:\\Python27\\geckodriver.exe");
WebDriver driver = new RemoteWebDriver(new URL("http://192.168.0.153:5555/wd/hub"), capability);
//打开必应搜索网站
driver.get("http://www.bing.com");
//获取关键字的输入框
WebElement inputBox = driver.findElement(By.id("sb_form_q"));
//输入搜索关键字
inputBox.sendKeys("赵薇");
//获取搜索的按钮
WebElement searchButton = driver.findElement(By.id("sb_form_go"));
//点击搜索
//searchButton.click();
searchButton.sendKeys(Keys.ENTER);
//
Thread.sleep(3000);
//获取服务器返回的搜索结果页面的html源码
String html = driver.getPageSource();
//验证结果
//assertEquals(html.contains("万家文化（现为祥源文化）收购案的失败"),true);
assertEquals(html.contains("黄有龙"),true);
//等待3秒钟
Thread.sleep(3000);
//关闭火狐浏览器
driver.quit();
}
}
7、远程操纵Chrome浏览器的Java代码
package com.yzc.mysystem.test;
import static org.testng.Assert.assertEquals;
import java.net.URL;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.Test;
public class RemoteChromeTest {
@Test
public void f() throws Exception {
DesiredCapabilities capability = DesiredCapabilities.chrome();
capability.setBrowserName("chrome");
capability.setPlatform(Platform.WINDOWS);
//capability.setVersion("61");
//System.setProperty("webdriver.gecko.driver","D:\\Python27\\geckodriver.exe");
WebDriver driver = new RemoteWebDriver(new URL("http://192.168.0.153:5555/wd/hub"), capability);
//打开必应搜索网站
driver.get("http://www.bing.com");
//获取关键字的输入框
WebElement inputBox = driver.findElement(By.id("sb_form_q"));
//输入搜索关键字
inputBox.sendKeys("赵薇");
//获取搜索的按钮
WebElement searchButton = driver.findElement(By.id("sb_form_go"));
//点击搜索
//searchButton.click();
searchButton.sendKeys(Keys.ENTER);
//
Thread.sleep(3000);
//获取服务器返回的搜索结果页面的html源码
String html = driver.getPageSource();
//验证结果
//assertEquals(html.contains("万家文化（现为祥源文化）收购案的失败"),true);
assertEquals(html.contains("黄有龙"),true);
//等待3秒钟
Thread.sleep(3000);
//关闭浏览器
driver.quit();
}
}
8、远程操纵IE浏览器的Java代码
package com.yzc.mysystem.test;
import static org.testng.Assert.assertEquals;
import java.net.URL;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.Test;
public class RemoteInternetExplorerTest {
@Test
public void f() throws Exception {
DesiredCapabilities capability = DesiredCapabilities.internetExplorer();
capability.setBrowserName("internet explorer");
capability.setPlatform(Platform.WINDOWS);
//capability.setVersion("61");
//System.setProperty("webdriver.gecko.driver","D:\\Python27\\geckodriver.exe");
WebDriver driver = new RemoteWebDriver(new URL("http://192.168.0.153:5555/wd/hub"), capability);
//打开必应搜索网站
driver.get("http://www.bing.com");
//获取关键字的输入框

//点击搜索
//searchButton.click();
searchButton.sendKeys(Keys.ENTER);
//
Thread.sleep(3000);
//获取服务器返回的搜索结果页面的html源码
String html = driver.getPageSource();
//验证结果
//assertEquals(html.contains("万家文化（现为祥源文化）收购案的失败"),true);
assertEquals(html.contains("黄有龙"),true);
//等待3秒钟
Thread.sleep(3000);
//关闭浏览器
driver.quit();
}
