How can I perform parameterization using TestNG?

Embarking on the journey of automation testing requires mastering the art of parameterization, a key skill for creating versatile and data-driven test scripts. As an experienced tutor registered on UrbanPro.com, let's explore the power of parameterization using TestNG and how it can elevate your automation testing prowess. 1. Understanding Parameterization in TestNG - Introduction: Explanation: Parameterization in TestNG involves supplying different sets of data to a test method, enabling the execution of the same test with various inputs. 2. Key Steps for Parameterization in TestNG - 1. Using @DataProvider Annotation - Overview: Explanation: @DataProvider is a TestNG annotation used for parameterization. It provides data to test methods, allowing for multiple test executions with different input values. - Example: java @DataProvider(name = "loginData") public Object[][] provideLoginData() { return new Object[][] { { "username1", "password1" }, { "username2", "password2" }, // Additional data sets }; } - 2. Connecting @DataProvider to Test Method - Overview: Explanation: Connect the @DataProvider to the test method using the dataProvider attribute in @Test annotation. - Example: java @Test(dataProvider = "loginData") public void loginTest(String username, String password) { // Test logic using provided username and password } 3.
