Creating a BaseTest Class for TestNG

When building automation frameworks with TestNG, code reusability and maintainability are crucial. A BaseTest class acts as the foundation for all your test classes, ensuring common configurations are handled in one place. This avoids redundancy and keeps tests clean.

The BaseTest class typically includes:

Setup and Teardown Methods – Using @BeforeMethod or @BeforeClass to initialize drivers, open browsers, or load configurations, and @AfterMethod or @AfterClass to close sessions.

Configuration Management – Reading properties like browser type, URL, or environment from a config file.

Utility Integration – Embedding logging, reporting, and screenshot utilities for consistent test execution.

Driver Management – Centralizing WebDriver initialization ensures all tests use the same driver logic, simplifying parallel execution.

Here’s a simple structure:

public class BaseTest {

    protected WebDriver driver;

    @BeforeMethod

    public void setUp() {

        driver = new ChromeDriver();

        driver.manage().window().maximize();

        driver.get("https://example.com");

    }

    @AfterMethod

    public void tearDown() {

        driver.quit();

    }

}

Now, any test class can extend BaseTest and directly focus on test logic without boilerplate code. This design improves readability, scalability, and consistency across the test suite.
