📌 What is a TestNG Annotation?

TestNG Annotations are Java annotations (starting with @) that control how and when your Selenium test methods execute. They define the lifecycle of your test framework including setup, execution, and teardown.

🔧 Exact Use of TestNG Annotations

• ✅ Initialize browser and environment
• ✅ Control test execution order
• ✅ Handle preconditions and post-conditions
• ✅ Group and prioritize test cases
• ✅ Support data-driven testing

💻 Practical Example (Selenium + TestNG)

import org.testng.annotations.*;

public class TestNGFlowDemo {

    @BeforeSuite
    public void setupSuite() {
        System.out.println("BeforeSuite - Setup reports");
    }

    @BeforeClass
    public void launchBrowser() {
        System.out.println("BeforeClass - Launch Browser");
    }

    @BeforeMethod
    public void beforeEachTest() {
        System.out.println("BeforeMethod - Navigate to URL");
    }

    @Test
    public void loginTest() {
        System.out.println("Test - Login Test");
    }

    @AfterMethod
    public void afterEachTest() {
        System.out.println("AfterMethod - Logout");
    }

    @AfterClass
    public void closeBrowser() {
        System.out.println("AfterClass - Close Browser");
    }

    @AfterSuite
    public void teardownSuite() {
        System.out.println("AfterSuite - Generate Report");
    }
