RK: write an example of constructor in automation testing

AI: Here is an example of a constructor in automation testing using the Selenium WebDriver:

public class TestClass {
    private WebDriver driver;

    public TestClass() {
        // Set the system property for the driver executable path
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver.exe");

        // Create a new instance of the Chrome driver
        driver = new ChromeDriver();

        // Maximize the browser window
        driver.manage().window().maximize();
    }
    
    // Other test methods would go here, such as test cases
    public void testMethod1() {
        // Test steps using the driver
    }

    public void testMethod2() {
        // Test steps using the driver
    }
}

The constructor is the method that is called when an object of the class is created. In this example, the constructor sets the system property for the chrome driver executable, creates a new instance of the Chrome driver, and maximizes the browser window. This is done so that whenever an object of the TestClass is created, the Chrome browser will be launched and maximized, so that the tests can be executed.

This example is using ChromeDriver but you can use other drivers like Firefox, Edge, etc.

It’s important to note that this is just a basic example, you would need to adjust the code according to your test needs, and to consult the Selenium documentation for more information on how to use the WebDriver and constructors.
