1. Understanding Parameterization in TestNG

- Introduction:

  • Explanation:

- 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 }
