TestNG Annotations

What are Annotations?

• Meta-tags which provides information to the test methods.

Why do we need to use it?

• To maintain a structured, readable , user-friendly testcases

When to use annotation?

• To control the execution order and behaviour of the test methods.

Annotations

Available annotations in Testng are:

• @BeforeSuite
• @BeforeTests
• @BeforeClass
• @BeforeMethod
• @Test
• @AfterMethod
• @AfterClass
• @AfterTest
• @AfterSuite
• @DataProvider

Annotations

• Annotation Hierarchy

• @BeforeSuite

  • @BeforeTests
    • @BeforeClass
      • @BeforeMethod
        • @Test
      • @AfterMethod
    • @AfterClass
  • @AfterTest

• @AfterSuite

@BeforeAll

• @Before->All the @Before annotations will be running before the testcases and are used
  to setup the pre-conditions

@AfterAll

• @After→ All the @After annotations will be running after the testcases and are used to
  setup the post-conditions

Annotations

• Suite →represents one xml file

@BeforeSuite:

• Configured to run the method once before all the tests in the suite -following which all other
  annotation will execute

@AfterSuite:

• Method will run after the all other annotations defined for the testcases.

@BeforeTest:

• Configured to run the method once before each (test modules) .

@AfterTest:

• Method will run for after every (test modules) is executed .

@BeforeTest:

• Configured to run the method once before each (test modules) .This annotation is typically used to
  set up resources that will be used by all test methods in the suite.

@AfterTest:

• Method will run for after every (test modules) is executed .

@BeforeClass:

• Configured to run the method once before all in the test. This annotation is typically used to set
  up resources that will be used by all test methods in the suite.

@AfterClass:

• Configured to run the method after every in the test. This annotation is typically used to set up
  resources that will be used by all test methods in the suite

@BeforeMethod:

• Configured to run the method once before each @Test method.

Example:

    @BeforeMethod
    public void preCondition() {
        EdgeDriver driver = new EdgeDriver();
    }

@AfterMethod

• Configured to run the method after each @Test method.
• Example:

    @AfterMethod
    public void postCondition() {
        driver.close();
    }

Classroom Activity (Breakout)

• Step:1 Create a class as BaseClass
• Step:2 Move all the common steps to common class (remove those steps in testcases)
• Step:3 @BeforeMethod and @AfterMethod annotation to define the preCondition and
  postCondition Methods
• Step:4 Extend the base class to leads classe
