一、启动浏览器

Selenium API :

https://seleniumhq.github.io/selenium/docs/api/java/index.html

1、启动Firefox浏览器

。准备工作

• 下载firefox驱动geckodriver（注意浏览器的版本）

https://github.com/mozilla/geckodriver/releases

• 火狐浏览器的版本

http://ftp.mozilla.org/pub/firefox/releases/

package cn.test;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class OpenBrower_Firefox {
    private WebDriver driver;

    @Before
    public void setUp() {
        System.setProperty("webdriver.gecko.driver", "libs/geckodriver.exe");
        driver = new FirefoxDriver();
    }
    @After
    public void tearDown() {
        driver.quit();
    }
    @Test
    public void openBrower() throws Exception {
        driver.get("https://www.baidu.com/");       
        Thread.sleep(2000);
        driver.findElement(By.id("kw")).clear();
        driver.findElement(By.id("kw")).sendKeys("你好");
        Thread.sleep(2000);
        driver.findElement(By.id("su")).click();
        Thread.sleep(2000);
        
    }
}

。启动本地机的Firefox配置

因为WebDriver启动firefox时是启动一个全新的浏览器，我们又想用到自己下载的插件，就可以使用如下的方法启动本地机的profile配置，也就是说我们先设置好需要用到的插件到firefox里面，然后启动WebDriver，就可以直接使用了。

• 设置firefox的profile

Win+R---输入firefox.exe -p----回车

可以自己常见配置文件

• 代码如下

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.firefox.ProfilesIni;

public class OpenBrower_Firefox {
    private WebDriver driver;

    @Before
    public void setUp() {
        
        ProfilesIni pi=new ProfilesIni();
        FirefoxProfile profile=pi.getProfile("selenium");
        System.setProperty("webdriver.gecko.driver", "libs/geckodriver.exe");
        FirefoxOptions options=new FirefoxOptions();
        options.setProfile(profile); 
        driver = new FirefoxDriver(options);
    }
    @After
    public void tearDown() {
        driver.quit();
    }
    @Test
    public void openBrower() throws Exception {
        driver.get("https://www.baidu.com/");       
        Thread.sleep(2000);
        driver.findElement(By.id("kw")).clear();
        driver.findElement(By.id("kw")).sendKeys("你好");
        Thread.sleep(2000);
        driver.findElement(By.id("su")).click();
        Thread.sleep(2000);
        
    }
}

2、启动Chrome浏览器

。Chrome浏览器的驱动下载地址

http://chromedriver.storage.googleapis.com/index.html

public class OpenBrower_Chrome {
    private WebDriver driver;
    @Before
    public void setUp() {
        System.setProperty("webdriver.chrome.driver", "libs\\chromedriver.exe");
        driver=new ChromeDriver();
    }
    @Test
    public void testOpen() throws Exception {
        driver.get("https://www.baidu.com/");
        Thread.sleep(2000);
        driver.findElement(By.id("kw")).sendKeys("八戒");
        Thread.sleep(2000);
        driver.findElement(By.id("su")).click();
        Thread.sleep(2000);
        
    }
    @After
    public void tearDown() {
        driver.close();
    }
}

3、启动IE浏览器

。IE浏览器的驱动下载地址

https://selenium-release.storage.googleapis.com/index.html

。配置IE浏览器的Internet选项

• 工具-Internet选项-安全
• 2、在Internet，本地Internet，受信任的站点，受限制的站点中去掉《启用保护模式》复选中的“√”

• 3、点击“确定”，即可

public class OpenBrower_IE {
    private WebDriver driver;

    @Before
    public void setUp() {
        System.setProperty("webdriver.ie.driver", "libs\\IEDriverServer.exe");
        driver = new InternetExplorerDriver();
        System.out.println("@Before");
    }

    @After
    public void tearDown() {
        driver.quit();
        System.out.println("@After");
    }

    @Test
    public void testDemo() throws Exception {

        driver.get("https://www.baidu.com/");
        Thread.sleep(2000);
        driver.findElement(By.id("kw")).sendKeys("八戒");
        Thread.sleep(2000);
        driver.findElement(By.id("su")).click();
        Thread.sleep(2000);

        System.out.println("@Test");
    }

    @Test
    public void testDemo2() throws Exception {

        driver.get("https://www.baidu.com/");
        Thread.sleep(2000);
        driver.findElement(By.id("kw")).sendKeys("八戒");
        Thread.sleep(2000);
        driver.findElement(By.id("su")).click();
        Thread.sleep(2000);

        System.out.println("@Test");
    }
}

• 如果不设置IE的话，会出现如下错误

org.openqa.selenium.NoSuchWindowException: Unable to find element on
