TestNG Annotations

Common Annotations

• @Test — marks a method as a test case.
• @BeforeMethod / @AfterMethod — run before/after each test method.
• @BeforeClass / @AfterClass — run once before/after all tests in a class.
• @BeforeSuite / @AfterSuite — run once before/after the entire suite.
• @DataProvider — supplies multiple sets of data to a test method for data-driven testing.

Why Annotations Matter

Annotations let testers precisely control the setup and teardown lifecycle around each test, avoiding repeated boilerplate code.
