TestNG Parameterized Test using @DataProvider

One of the bright feature of TestNG is that to allows pass parameter to test. It can be achieve in two ways...

1. using @DataProvider annotation and

2. with testng.xml

Here is a demonstration how to parameterized test using @DataProvider annotation.

The Data Provider method returns an array of Objects(Objects[][])  where the first dimension's size is the number of times the test method will be invoked and the second dimension size contains an array of objects that must be compatible with the parameter types of the test method.

Thread.sleep(1000);

String actual_PageTitle = driver.getTitle();  //Actual Result

Assert.assertEquals(actual_PageTitle, expected_PageTitle);  //Compare actual with expected result
