36 – TestNG Testing Framework for Selenium

Selenium Class 36 – TestNG Testing Framework for Selenium

1) Introduction to TestNG Testing Framework
2) Install TestNG and write first TestNG program
3) Create multiple Test cases and run
4) TestNG Annotations
5) Execute multiple Programs / Classes using XML
6) Grouping Test Cases
7) Data driven testing using @DataProvider Annotation
8) Parallel Test Execution

In Selenium using Java, there are two Testing Frameworks available,
i) JUnit
ii) TestNG,

Note:
Java – JUnit, TestNG
C#.NET – NUnit
PHP – Behat+Mink
Ruby – Repect, Test:Unit,
Python – PyUnit, Py:Test

1) Introduction to TestNG Testing Framework

• TestNG Testing Framework was designed to simplify a broad range of testing needs from Unit Testing to System Testing….
• Initially developed for Unit Testing, now used for all levels of Testing
• TestNG is open source software, where NG stands for next Generation
• TestNG inspired by JUnit and NUnit and introduced some new functionalities

Advantages of TestNG for Selenium:

• TestNG Annotations are easy to create Test Cases
• Test cases can be grouped and prioritized more easily
• Executes multiple programs/Classes using XML
• Parallel Testing
• Generates Test Reports
  Etc…

2) Install TestNG and write first TestNG program

Navigation to install TestNG on Eclipse IDE,

In Eclipse IDE,

• Help Menu,
• Select “install New Software”
• Click “Add”
• Enter name as “TestNG”
• Enter URL as “http://beust.com/eclipse/
• Click OK
  Then “TestNG” will be populated,
• Select “TestNG”
• Next
• Next
• accept the agreement
• Finish

Write TestNG program/Test Case

a) Manual Test case

Test Case name: Verify page Title (Google)

Test Steps:
i) Launch the Browser
ii) Navigate to Google Home page (https://www.google.com/)

Expected Result:
“Google”

Verification Point:
Capture the Page Title and compare with expected

Test Data/Input:
NA

TestNG Test Case:

i) main method is not used in TestNG programs
ii) TestNG programs contain methods only that contain Annotations
iii) If we don’t write @Test Annotation then the method won’t be executed

public class VerifyTitle {
WebDriver driver;
@Test
public void verifyTitle(){
System.setProperty(“webdriver.chrome.driver”, “E:/chromedriver.exe”);
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get(“https://www.google.com/”);
String pageTitle = driver.getTitle();

/if (pageTitle.equals(“Google2”)){ System.out.println(“Google Application was Launched – Passed”); } else { System.out.println(“Google Application was Not Launched – Failed”); }/
Assert.assertEquals(“Google”, pageTitle);
}
@AfterMethod
public void closeBrowser(){
driver.close();
}
}
