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
