这里采用的是Selenium3.7版本，首先介绍的是在Windows环境下运行的；

总结下注意事项：

1，设置各个浏览器的Driver路径

System.setProperty("","");

2，创建一个浏览器对象

WebDriver driver = new xxx();

1. 驱动IE浏览器

IE浏览器的驱动有32位和64位，两个版本，建议使用32的IEdriver，因为64位的IE driver 跑起来实在太慢了。

注意IE的保护模式，在各个状态下，全部禁用。如下截图，4个模式下，保护模式全部 不勾选 。

 package base;

 import java.util.concurrent.TimeUnit;

 import org.openqa.selenium.WebDriver;

 import org.openqa.selenium.ie.InternetExplorerDriver;

 public class TestIEDriver {

     public static void main(String args[]) throws InterruptedException {

         System.setProperty("webdriver.ie.driver", ".\\Tools\\IEDriverServer.exe");

         WebDriver driver = new InternetExplorerDriver();

         driver.manage().window().maximize();

         driver.get("http://www.baidu.com");

         String s = driver.getTitle();

         System.out.print(s);

         driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

         Thread.sleep(1000);

         driver.close();

     }

 }

2. 驱动Chrome浏览器

 package base;

 import java.util.Arrays;

 import java.util.concurrent.TimeUnit;

 import org.openqa.selenium.WebDriver;

 import org.openqa.selenium.chrome.ChromeDriver;

 import org.openqa.selenium.chrome.ChromeOptions;

 import org.openqa.selenium.remote.DesiredCapabilities;

 public class TestChromeDriver {

     public static void main(String args[]) throws InterruptedException {

         System.setProperty("webdriver.chrome.driver", ".\\Tools\\chromedriver.exe");

         ChromeOptions options = new ChromeOptions();

         DesiredCapabilities capabilities = DesiredCapabilities.chrome();

         capabilities.setCapability("chrome.switches", Arrays.asList("--start-maximized"));

         options.addArguments("--test-type", "--start-maximized");

         WebDriver driver = new ChromeDriver(options);

         driver.get("http://www.baidu.com");

         driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

         Thread.sleep(1000);

         driver.close();

     }

 }

3. 驱动火狐FireFox浏览器

 package base;

 import java.util.concurrent.TimeUnit;

 import org.openqa.selenium.WebDriver;

 import org.openqa.selenium.firefox.FirefoxDriver;

 public class TestFireFoxDriver {

     public static void main(String args[]) throws InterruptedException {

         System.setProperty("webdriver.Firefox.driver", ".\\Tools\\geckodriver.exe");

         WebDriver driver = new FirefoxDriver();

         driver.manage().window().maximize();

         driver.get("http://www.baidu.com");

         String s = driver.getTitle();

         System.out.print(s);

         driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

         Thread.sleep(1000);

         driver.close();

     }

 }

常见的错误汇总

1. org.openqa.selenium.remote.SessionNotFoundException: Unexpected error launching Internet Explorer. Browser zoom level was set to 75%. It should be set to 100% (WARNING: The server did not provide any stacktrace information)

ie浏览器显示百分比，需要调节到100%

2. org.openqa.selenium.ElementNotVisibleException: The point at which the driver is attempting to click on the element was not scrolled into the viewport. (WARNING: The server did not provide any stacktrace information)

不同设备，窗口大小问题，页面没有显示全，需要向下滚动

3.org.openqa.selenium.SessionNotCreatedException: session not created exception: Chrome version must be >= 66.0.3359.0

Chrome浏览器驱动版本不匹配的问题，需要查询目前chrome版本，下载匹配的驱动

4.No such Element Exception
元素定位的方式有误，原因：页面源码改动
原因：元素还不是可用的状态
原因：出现弹窗
