Automated Testing Using Selenium Webdriver and TestNG

Hello  all, Welcome back. So this blog is with regard to automated testing using Selenium Web driver and TestNG.
Before talking about the the procedure of performing the testing functionalities I'll explain you in  a nutshell on what automated testing is

As the name suggests Automated testing is the testing done without manually entering data, without the direct involvement of a user, performed with a testing tool. Here virtual users are created.

Wikipedia says "In software testing, test automation is the use of special software (separate from the software being tested) to control the execution of tests and the comparison of actual outcomes with predicted outcomes."

So coming back to our testing procedure...

Out intention- To test the functionalities of www.gov.lk website.

What do we use?

• An IDE (Eclipse/NetBeans etc.)- I use Netbeans here(should have installed JDK as well)
• Selenium WebDriver
• TestNG                                                                                                                                           

One small question before starting..so why do we need TestNG other than Selenium Webdriver here?
Because TestNg can generate reports(in a readable format as shown below) based on our Selenium test results. Web driver has no native mechanism for generating reports.

So let's start.

Prior requirement-
You have to download the following files and folders from the site http://www.seleniumhq.org/download/

• selenium-server-standalone-2.53.1.jar
• selenium-java-2.53.1.jar >> A
• selenium-java-2.53.1.-srcs.jar>>B
• selenium-java-2.53.1 (folder)>>C 

First of all create a project in your IDE. I've choosen the name FirstTestNG.

Then, since we are hoping to test the script with TestNG and in order to create an empty test case create a TestNG class. For that,
Right click on Source Packages>>New>>Other>>Unit Test>>TestNG Test  Case>>Give the class name you prefer>>Click Finish

Here I've given the name MyFirst.

Then import the files that we have downloaded previously. For that,
Right click libraries>>Add JAR/Folder... and import the files.
I've named the folders and files as A,B,C for the convenience. A,B,C  are in one zip folder. Extract it and import A and B separately.Next, Zip the "C" folder again and import it.

Now you're done with importing all the files.
Now let's see the test scenarios  that we will try on.

• The language functionality
• The search functionality
• Select  ‘Reservation of Seats in Trains’ services and verify the site is loading properly.

So now lets move on to the code......

@Test

    String actualWelcomeTitle = driver.getTitle();
    System.out.println(actualWelcomeTitle);
    String portalWelcomeTitle = "Government of Sri Lanka - Welcome";
   
    Assert.assertEquals(portalWelcomeTitle, actualWelcomeTitle);
   
    driver.findElement(By.linkText("English")).click();  //Checking the language selection functionality
    System.out.println("Successfully selected English language");
   
    driver.findElement(By.id("mainSearch")).sendKeys("Train");  //Verification of search functionality
    System.out.println("Successfully typed Train");
   
    driver.findElement(By.id("mainSearch")).sendKeys(Keys.ENTER);
    Thread.sleep(10000);
   
    driver.switchTo().frame("contentFrame");
   
    if(driver.findElement(By.xpath("//a[contains(text(),'Reservation of Seats in Trains')]")).isDisplayed()){//Checking the link Reservation of seats in trains
       
    driver.findElement(By.xpath("//a[contains(text(),'Reservation of Seats in Trains')]")).click();         System.out.println("Successfully clicked reservation of seats in trains");
   
    Thread.sleep(8000);
    Set<String> allWindows = driver.getWindowHandles();
   
    String newWindow = allWindows.iterator().next();
    driver.switchTo().window(newWindow);
    System.out.println(driver.getTitle());
   
    Thread.sleep(3000);
   
    driver.close();
    }
    }
@AfterMethod
public void tearDownMethod() throws Exception {
    driver.quit();
}
}


The phrases marked in red are TestNG annotations.
You can find more on TestNG annotations through the below link.

After typing the code run the test file using TestNG. For that right click on the code and click test File.
If the test ran successfully a test report as shown below will be generated.

 The below table shows the test cases for the above 3 tests which we have run using TestNG.
