Selenium中常常会出现的问题

//因为Selenium默认的是firefox浏览器

import org.openqa.selenium.ie.InternetExplorerDriver;import org.openqa.selenium.By;import org.openqa.selenium.WebDriver;import org.openqa.selenium.WebElement;public class Project1Class {    public static void main(String[] args) {        WebDriver driver = new InternetExplorerDriver();      }    }

Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.ie.driver system property; for more information, see https://github.com/SeleniumHQ/selenium/wiki/InternetExplorerDriver. The latest version can be downloaded from http://selenium-release.storage.googleapis.com/index.html

应该改为：需要设置相应的浏览器的位置等等属性。

import org.openqa.selenium.ie.InternetExplorerDriver;import org.openqa.selenium.By;import org.openqa.selenium.WebDriver;import org.openqa.selenium.WebElement;public class Project1Class {    public static void main(String[] args) {        System.setProperty("webdriver.ie.driver", "C:\\Program Files\\Internet Explorer\\iexplore.exe");          WebDriver driver = new InternetExplorerDriver();      }    }

google浏览器也会发同样的错误，也是同样的解决方法：
eg：代码

import org.openqa.selenium.ie.InternetExplorerDriver;import org.openqa.selenium.By;import org.openqa.selenium.WebDriver;import org.openqa.selenium.WebElement;import org.openqa.selenium.chrome.ChromeDriver;public class Project1Class {    public static void main(String[] args) {         System.setProperty("webdriver.chrome.driver", "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");          WebDriver driver = new ChromeDriver();      }    }

好像如果需要进行绘画的话，需要下载相应版本的插件。

同样的范式也解决了opera浏览器的放，
需要修改的地方是：

第一个参数：

System.setProperty("webdriver.chrome.driver", "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
增加，webdriver.chrome.driver" 中的chrome名字改为相应的浏览器名字，
第二个参数：

修改浏览器的路径

但是同样出现一个问题而还没有解决的：

（浏览器不能够进行运行）
