TestNG Annotations

Annotations:

TestNG Framework in Selenium Webdriver having different annotations which will be very useful during Framework Development.

@BeforeMethod
@AfterMethod
@Test
@BeforeTest
@AfterTest
@BeforeClass
@AfterClass
@BeforeSuite
@AfterSuite

Before getting into details about annotaions i will show the hierarchy for better understanding.

@BeforeSuite

@BeforeTest

@BeforeClass

@BeforeMethod

@Test

@AfterMethod

@AfterClass

@AfterTest

@AfterSuite

1) @BeforeMethod:

This method is executed before every testcase. suppose we are having 2 testcases then this method will execute one time for Before testcase1 and another time for Before testcase2.

2) @AfterMethod:

Same as Before method but ,This method is executed After every testcase. suppose we are having 2 testcases then this method will execute one time for After testcase1 and another time for After testcase2.

3) @BeforeClass:

This Annotation is executed once per Before class.Suppose we are having 2 tescases in a class then this annotaion will be executed once Before Class.

4) @AfterClass:

Same as Before class but,This Annotation is executed once per After class.Suppose we are having 2 tescases in a class then this annotaion will be executed once After Class.

5) @Test:

This Annotation represents that this is the TestCase.

6) @BeforeTest:

This annotation is executed once Before all Testcase and class.suppose we are having 2 classes then this will execute once Before all the classes.

7) @AfterTest:

This annotation is executed once After all Testcase and class.suppose we are having 2 classes then this will execute once After all the classes.

8) @BeforeSuite:

This annotation is executed FIRST, of all annotations present in all classes.

9) @AfterSuite:

This annotation is executed LAST, of all annotations present in all classes.

Example Program:

public class AnnotExample
{

@BeforeMethod
  public void m1()
  {
System.out.println("Before-Method");
}

@Test
  public void Testcase1()
  {
System.out.println("TEST_CASE1");
  }

@Test
  public void TestCase2()
  {
System.out.println("Test-Case2");
  }

@AfterMethod
  public void m2()
  {
System.out.println("After-Method");
  }

@BeforeClass()
  public void m3()
  {
System.out.println("Before-Class");
  }

@AfterClass()
  public void m4()
  {
System.out.println("After-Class");
  }

@BeforeTest()
  public void m5()
  {
System.out.println("Before-Test");
  }

@AfterTest()
  public void m6()
  {
System.out.println("After-Test");
  }

@BeforeSuite
  public void m7()
  {
System.out.println("Before-Suite");
  }

@AfterSuite
  public void m8()
  {
System.out.println("After-Suite");
  }

}

OUTPUT:

Before-Suite
Before-Test
Before-Class
Before-Method
Test-Case2
After-Method
Before-Method
TEST_CASE1
After-Method
After-Class
After-Test
PASSED: TestCase2
PASSED: Testcase1
