System.out.println("Attribute HREF Value="+attr2);



O/P :

Attribute ID Value= Link1

Attribute HREF Value=http:gmail.com

Data driven testing in TestNG (Using @DataProvider annotaion)

-> @DataProvider annotations in TestNG is important for data driven framework in selenium.

-> @DataProvider Annotation of testng framework provides us a facility of storing and preparing data set In method.

-> Task for @DataProvider Annotation is supplying data for test method. That means we can configure data with in the @DataProvider annotations and use those data inside the @Test methods.

-> @dataprovider method should return an Object[][] with data.

-> we have to create two dimensional array in @DataProvider annotation data to stored the data.



Example:


Bellow given example will retrieve userid and password one by one from @DataProvider annotated method and will feed them In LogIn_Test(String Usedid, String Pass) one by one. Run this example In your eclipse and observe result.



public class Sample_Login {

 WebDriver driver = new FirefoxDriver();


 @BeforeTest
    public void setup() throws Exception {
         driver.manage().window().maximize();
         driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
         driver.get("http://only-testing-blog.blogspot.in/2014/05/login.html");
    }


  @AfterTest
 public void tearDown() throws Exception {
   driver.quit();
     }


 //This method will return two dimensional array.
 //This method behaves as data provider for LogIn_Test method.

 @DataProvider

 public Object[][] LoginCredentials(){

  //Created two dimensional array with 4 rows and 2 columns.
  //4 rows represents test has to run 4 times.
  //2 columns represents 2 data parameters.

 Object[][] Cred = new Object[4][2];

  Cred[0][0] = "UserId1";
  Cred[0][1] = "Pass1";

  Cred[1][0] = "UserId2";
  Cred[1][1] = "Pass2";

  Cred[2][0] = "UserId3";
  Cred[2][1] = "Pass3";

  Cred[3][0] = "UserId4";
  Cred[3][1] = "Pass4";
  return Cred; //Returned Cred
 }



 //Give data provider method name as data provider.
 //Passed 2 string parameters as LoginCredentials() returns 2 parameters In object.

 @Test(dataProvider="LoginCredentials")

 public void LogIn_Test(String Usedid, String Pass){
   driver.findElement(By.xpath("//input[@name='userid']")).clear();
   driver.findElement(By.xpath("//input[@name='pswrd']")).clear();
   driver.findElement(By.xpath("//input[@name='userid']")).sendKeys(Usedid);
   driver.findElement(By.xpath("//input[@name='pswrd']")).sendKeys(Pass);
   driver.findElement(By.xpath("//input[@value='Login']")).click();
   String alrt = driver.switchTo().alert().getText();
   driver.switchTo().alert().accept();
   System.out.println(alrt);
  }
}




testng.xml file to run this example Is as bellow.


<suite name="Simple Suite">
 <test name="Simple Skip Test">
  <classes>
   <class name = "Testng_Pack.Sample_Login"/>
  </classes>
 </test>
</suite>




After run the above code, the user id and password entered one by one in above URL.

Selenium WebDriver Parallel Tests Execution Using TestNG - @Parameters

-> Browser compatibility testing Is most Important thing for any web application and generally you have to perform browser compatibility testing before 1 or 2 days of final release of application. In such a sort time period, you have to verify each Important functionality In every browsers suggested by client.


-> If you will go for running your all webdriver tests In each browsers one by one then It will take too much time to complete your test and you may not complete It before release.

-> In such situation, Running your tests In all required browsers at same time will helps you to save your time efforts.

-> The above situation solved in selenium by using @Parameters annotation in TestNG framework.



Parallelism In TestNG


We can configure our TestNG.xml file in such a way to run our test suite or tests or methods in seperate browsers Is known as parallelism In TestNG.


ParellelTestng.java


package TestNG_Package;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class TestNG_Test1 {

 private  WebDriver driver1=null;

  @BeforeClass
  @Parameters ({"browser"})

  public void setup(String browser)
 {
   if (browser.equals("FFX"))
  {
     System.out.println("Test Starts Running In Firefox Browser.");
     driver1 = new FirefoxDriver(); 
    }
  else if (browser.equals("CRM"))
  {
     System.out.println("Test Starts Running In Google chrome.");
     System.setProperty("webdriver.chrome.driver",  "D:\\chromedriver_win32_2.3\\chromedriver.exe");
     driver1 = new ChromeDriver(); 
   }
   driver1.manage().window().maximize();
   driver1.get("http://only-testing-blog.blogspot.in/2014/05/login.html");
  }


 @AfterClass
 public void closebrowser()
 {
    driver1.quit();
 }


 @Test
 public void MethodOne() {

  String a= "Selenium";
  if(a.equals("Selenium")
   throw new SkipException("Skipped");

  String title = driver1.getTitle();
  System.out.println("title"+title);   
 }



 @Test
 public void MethodTwo() {
  String title = driver1.getTitle();
  System.out.println("title"+title);   
 }


}




testng.xml

<suite name="webDriver" parallel="tests">

 <test name="Test In FireFox" >
    <parameter name="browser" value="FFX" />
    <classes>
      <class name="Testng_Pack.Test_Parallel" />
    </classes>
  </test>

   <test name="Test In Google Chrome" >
    <parameter name="browser" value="CRM"></parameter>
    <classes>
      <class name="Testng_Pack.Test_Parallel"></class>
    </classes>
  </test>

</suite>




From above example we can run same test in both Chrome and FireFox at same time.

From above Testng.xml file

-> parallel="tests" which inside <suite> tag will instruct TestNG to consider method of each <test> tag as seperate Thread. that Means If you wants to run your test In 2 different browsers then you need to create two <test> blocks for each browser Inside testng.xml file.

-> Inside each <test> tag block, define one more tag "parameter" with same name(In both <test> block) but with different values.Its used to pass in ParellelTestng.java method.



From ParellelTestng.java

-> Here we are used @Parameters annotation to pass parameter in method.Values of this parameter will be feed by testng.xml file.

-> If condition will check that value to decide which driver to use for test. This way, example testng.xml file will feed two values(FFX and CRM) In parameter so It will open Firefox and Google chrome browsers and run test In both browsers

How To Skip WebDriver Test In TestNG

We can skip the execution from perticular test by using throw new SkipException() exception. THis is TestNG exception.

Sometimes you need to check some condition like If some condition match then skip test else perform some action In your webdriver test. In this kind of situation, you can use SkipException() exception.


Consider below example




package TestNG_Package;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class TestNG_Test1 {
WebDriver driver1=new FirefoxDriver();
@BeforeMethod
public void OpenBrowser(){
driver1.get("http://google.com");
driver1.manage().window().maximize();
}
@AfterMethod
public void CloseBrowser(){
driver1.quit();
}
@Test
public void MethodOne() {

String a= "Selenium";
if(a.equals("Selenium")
throw new SkipException("Skipped");

String title = driver1.getTitle();
System.out.println("title"+title);   
}



@Test
public void MethodTwo() {
String title = driver1.getTitle();
System.out.println("title"+title);   
}


}



o/p

MethodOne Skipped due to SkipException()
MethodTwo executed


From above example if execution throw SkipExeption() means the rest of the commands inside the method wont get executed. Its skipped from current method and control goes to next method.
