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();    
  }
