Grouping Test Methods | TestNG

Test Methods are annotated with @Test;  These methods can be grouped and executed separately using TestNG framework.  The methods can also be executed based on the priority.

Please find a Test Suite with real-time implementation as given below,

public class classname{
private WebDriver driver;
private String baseUrl;  
  
  @BeforeTest(groups = { "Group1", "Group2" })
  public void setUp() throws Exception {
    driver = new FirefoxDriver();
    baseUrl = "http://www.justdial.com";
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
  }
  
  @Test(groups = { "Group1" }, priority=3)
  public void test1() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G1a");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G1a");
  }

  @Test(groups = { "Group1" }, priority=2)
  public void test2() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G1b");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G1b");
  }
  
  @Test(groups = { "Group2" })
  public void test3() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G2a");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G2a");
  }
  
  @Test(groups = { "Group1" }, priority=1)
  public void test4() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G1c");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G1c");
  }
  
  @Test(groups = { "Group2" })
  public void test5() throws Exception {
    driver.get(baseUrl + "/");
    driver.findElement(By.id("what")).sendKeys("G2b");
    driver.findElement(By.id("where")).sendKeys("Chennai");
    System.out.println("I am G2b");
  }

  @AfterTest(groups = { "Group1", "Group2" })
  public void tearDown() throws Exception {
    driver.quit();    
  }

HTMLUnitDriver Extra cover

HTMLUnitDriver is the fastest implementation of WebDriver. It is a java based implementation of a Web Browser without a GUI. For any language binding (other than java) the Selenium Server is required to use this driver. It supports JavaScript. JavaScript engine used by the HTMLUnit (Rhino) is different from other popular browsers. Testing JavaScript using HTMLUnit differ significantly with results.

Note:
Download the latest Selenium drivers[2.35 or above];  Older versions of Selenium won't work.

Handle Transparent Proxy 

HtmlUnitDriver driver = new HtmlUnitDriver();    
driver.setProxy("xxx.xxx.xxx.xxx", port);    //  set proxy for handling Transparent Proxy
driver.setJavascriptEnabled(true);    //  enable JavaScript [this emulate IE's js by default]


Emulate popular Browser's JS

HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.FIREFOX_17);
driver.setJavascriptEnabled(true);


Emulate specific Browser's JS using Capabilities

#1
DesiredCapabilities capabilities = DesiredCapabilities.htmlUnit();
driver = new HtmlUnitDriver(capabilities);
#2
DesiredCapabilities capabilities = DesiredCapabilities.firefox();  
capabilities.setBrowserName("Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0");
capabilities.setVersion("24.0");
driver = new HtmlUnitDriver(capabilities);
