How do TestNG annotations work? How do they differ from JUnit?

As an experienced tutor in automation testing registered on UrbanPro.com, I'll explain how TestNG annotations work and highlight the differences between TestNG and JUnit annotations. Understanding annotations is crucial for effective test case design and execution in the automation testing field. TestNG Annotations: How They Work 1. Introduction to TestNG Annotations a. Purpose: TestNG annotations are markers used to indicate the methods that will be run as tests, perform setup and teardown actions, and control the test execution flow. 2. Common TestNG Annotations a. 1. @Test: Purpose: Identifies a method as a test case. Example: java @Test public void yourTestMethod() { // Test logic goes here } b. 2. @BeforeMethod and @AfterMethod: Purpose: Execute setup and teardown actions before and after each test method. Example: java @BeforeMethod public void setUp() { // Setup actions } @AfterMethod public void tearDown() { // Teardown actions } c. 3. @BeforeClass and @AfterClass: Purpose: Execute setup and teardown actions once before and after all test methods in a class. Example: java @BeforeClass public void classSetup() { // Setup actions for the entire class } @AfterClass public void classTearDown() { // Teardown actions for the entire class } 3. Differences from JUnit Annotations a. 1. Flexible Configuration: TestNG: Provides more configuration options, allowing flexible test suite setup. JUnit: Limited configuration options compared to TestNG. b. 2. Parallel Execution: TestNG: Built-in support for parallel execution of tests. JUnit: Limited parallel execution capabilities. c. 3. Dependency Management: TestNG: Allows defining dependencies between test methods. JUnit: Limited support for defining and managing dependencies. Online Coaching on UrbanPro.com 1.
