Understanding TestNG Annotations:

Overview:

• TestNG annotations are markers that convey information to the TestNG framework, guiding the execution and behavior of test methods and classes.
• Annotations are crucial for configuring test methods, setting up preconditions, and influencing the flow of test execution.

Key TestNG Annotations:

1. @Test:

   • Identifies a method as a test method, indicating that TestNG should consider it during test execution.

2. @BeforeSuite:

   • Denotes a method that should run before all tests in a suite, providing a setup at the suite level.

3. @AfterSuite:

   • Marks a method that should run after all tests in a suite, allowing cleanup or finalization activities.

4. @BeforeTest:

   • Specifies a method that runs before any test method belonging to a <test> tag in the TestNG XML file.

5. @AfterTest:

   • Indicates a method that runs after all test methods belonging to a <test> tag in the TestNG XML file.

6. @BeforeClass:

   • Designates a method that runs before the first test method in the current class, enabling class-level setup.

7. @AfterClass:

   • Designates a method that runs after the last test method in the current class, facilitating class-level cleanup.

8. @BeforeMethod:

   • Specifies a method that runs before each test method, allowing method-specific setup.

9. @AfterMethod:

   • Denotes a method that runs after each test method, enabling method-specific cleanup.

10. @DataProvider:

    • Indicates that the annotated method supplies data for one or more test methods, facilitating data-driven testing.

11. @Parameters:

    • Enables the passing of parameters to test methods, enhancing test parameterization.

12. @Listeners:

    • Incorporates listeners to track test execution events, such as test start, failure, and success.

13. @Factory:

    • Enables the creation of a test class instance for each set of parameters, supporting dynamic test creation.

Integration in Automation Testing Coaching:
