一、在Eclipse中安装TestNG
1、打开eclipse-->help-->Install New Software-->Add,输入Name和Location后，点击OK。
TestNG官方下载地址：http://testng.org/doc/download.html
2、然后选中TestNG，单击Next安装
3、安装好TestNG后重启eclipse查看是否安装好，Help-->About Eclipse-->Installation Details，如图：
二、使用TestNG来运行单个测试案例：
1、新建TestHelloWorldTestNG.java类，目录结构如下：
2、测试代码：
1 package com.selenium;
2
3 import org.openqa.selenium.By;
4 import org.openqa.selenium.WebDriver;
5 import org.openqa.selenium.WebElement;
6 import org.openqa.selenium.firefox.*;
7 import org.testng.annotations.*;
8 import org.testng.Assert;
9
10
11 public class TestHelloWorldTestNG {
12
13 WebDriver driver;
14 @Test
15 public void helloWorld() throws Exception {
16 //如果火狐浏览器没有默认安装在C盘，需要制定其路径
17 //System.setProperty("webdriver.firefox.bin", "D:/Program Files/Mozilla firefox/firefox.exe");
18 driver = new FirefoxDriver();
19 driver.get("http://www.baidu.com/");
20
21 driver.manage().window().maximize();
22
23 WebElement txtbox = driver.findElement(By.name("wd"));
24 txtbox.sendKeys("Glen");
25
26 WebElement btn = driver.findElement(By.id("su"));
27 btn.click();
28
29 String expectedTitle = "Glen_百度搜索";
30 String actualTitle = driver.getTitle();
31
32 Assert.assertEquals(actualTitle,expectedTitle);
33 }
34
35 @AfterTest
36 public void tearDown(){
37 driver.quit();
38 }
39
40 }
3、然后右键Run As-->TestNG Test,运行结果如下：
[TestNG] Running:
C:\Users\Administrator\AppData\Local\Temp\testng-eclipse-332204777\testng-customsuite.xml PASSED: helloWorld ===============================================

[TestNG] Time taken by org.testng.reporters.XMLReporter@cdedfd: 11 ms
[TestNG] Time taken by org.testng.reporters.SuiteHTMLReporter@13caecd: 22 ms
三、使用TestNG来运行多个测试案例：
1、增加一个失败的测试类TestHelloWorldTestNG_Fail.java：
1 package com.selenium;
2
3 import org.openqa.selenium.By;
4 import org.openqa.selenium.WebDriver;
5 import org.openqa.selenium.WebElement;
6 import org.openqa.selenium.firefox.*;
7 import org.testng.annotations.*;
8 import org.testng.Assert;
9
10
11 public class TestHelloWorldTestNG_Fail {
12
13 WebDriver driver;
14 @Test
15 public void helloWorld() throws Exception {
16 //如果火狐浏览器没有默认安装在C盘，需要制定其路径
17 //System.setProperty("webdriver.firefox.bin", "D:/Program Files/Mozilla firefox/firefox.exe");
18 driver = new FirefoxDriver();
19 driver.get("http://www.baidu.com/");
20
21 driver.manage().window().maximize();
22
23 WebElement txtbox = driver.findElement(By.name("wd"));
24 txtbox.sendKeys("Glen");
25
26 WebElement btn = driver.findElement(By.id("su"));
27 btn.click();
28
29 String expectedTitle = "Glen_百度";
30 String actualTitle = driver.getTitle();
31
32 Assert.assertEquals(actualTitle,expectedTitle);
33 }
34
35 @AfterTest
36 public void tearDown(){
37 driver.quit();
38 }
39
40 }
2、在项目下新建一个Suite.xml文件：
<suite name="seleniumcn.cn.demo">
<test name="test_seleniumcn" >
<classes>
<class name="com.selenium.TestHelloWorldTestNG"/>
<class name="com.selenium.TestHelloWorldTestNG_Fail"/>
</classes>
</test>
</suite>
3、目录结构：
4、右键Suite.xml文件，Run As->TestNG Suite,如此就会运行suite.xml文件中所有的案例。
[TestNG] Running:
F:\workspace\WebDriverDemo\Suite.xml ===============================================
seleniumcn.cn.demo
Total tests run: 2, Failures: 1, Skips: 0
===============================================
5、右键WebDriverDemo刷新项目，目录中会新增加一个test.output文件夹，打开 index.html可以看一个简单的报告。
