As an experienced tutor in automation testing registered on UrbanPro.com, I'll guide you through the techniques for reusing the same WebDriver instance across different tests in TestNG, enhancing test efficiency and resource utilization.

Reusing WebDriver Instance in TestNG

1. Understanding TestNG Parallel Execution

a. Parallel Execution Modes
  • TestNG supports parallel test execution modes, including methods, tests, and suites.
  • Parallel execution can be configured in the TestNG XML file.

2. WebDriver as a Shared Resource

a. Singleton Design Pattern
  • Implement a Singleton design pattern for the WebDriver instance.
    • Ensures only one instance of WebDriver is created and shared across multiple tests.
b. ThreadLocal for WebDriver
  • Use ThreadLocal to store the WebDriver instance.
    • ThreadLocal allows each test thread to have its own WebDriver instance, preventing interference between parallel executions.

3. Sample Code for Reusing WebDriver

a. Singleton Implementation
java
public class WebDriverSingleton { private static WebDriver driver; private WebDriverSingleton() { // Private constructor to prevent instantiation } public static WebDriver getDriver() { if (driver == null) { // Initialize WebDriver (e.g., ChromeDriver, FirefoxDriver) // Example: driver = new ChromeDriver(); } return driver; } }
b. TestNG Test Class
java
public class MyTest { WebDriver driver; @BeforeClass public void setUp() { // Retrieve WebDriver instance from Singleton driver = WebDriverSingleton.getDriver(); } @Test public void test1() { // Test logic using the shared WebDriver instance } @Test public void test2() { // Test logic using the shared WebDriver instance } @AfterClass public void tearDown() { // No WebDriver quit/close to keep the instance available for other tests } }
