TestNG| Creating the First Case

How to create Test Case using TestNG?

Creating TestCase is simple using TestNG. The main motive to create a Test Case using TestNG is because of it powerful framework and to avoid main() method.

Steps to create a TestNG  Test case

• Ensure TestNG is correctly configured in Eclipse(Install TestNG)
• Import the Package import org.testng.annotations.* in the respective Class
• Use Annotation @ Test to run a particular Test Case
• Run the Program  as TestNG

Running the Program as a TestNG


The below diagram depicts the flow of Running of Test Cases in accordance to Annotations used

Flow of Running the Test NG Cases 

 import java.io.File;  
 import java.io.IOException;  
 import org.apache.commons.io.FileUtils;  
 import org.openqa.selenium.By;  
 import org.openqa.selenium.JavascriptExecutor;  
 import org.openqa.selenium.OutputType;  
 import org.openqa.selenium.TakesScreenshot;  
 import org.openqa.selenium.WebDriver;  
 import org.openqa.selenium.WebElement;  
 import org.openqa.selenium.chrome.ChromeDriver;  
 import org.openqa.selenium.firefox.FirefoxDriver;  
 import org.testng.annotations.*;  
 public class TestNGProgram {  
      public WebDriver driver;  
      @BeforeClass   
      public void setup()  
      {  
           this.driver=new FirefoxDriver();  
      }  
      @AfterClass  
      public void teardown()  
      {  
           this.driver.quit();  
      }  
      @Test  
      public void loadpage()  
      {  
           driver.get("https://www.facebook.com/");  
           String s =driver.getTitle();  
           System.out.println(s);  
      }  
 }  

Notes

1. this is a keyword in Java that can be used to refer current class instance variable hence it used to access the driver variable.
2. Order of execution of above tests annotation is @BeforeClass>@test>@AfterClass
3. There is no need to write main() method
4. Title of facebook page is fetched using getTitle() method
