Parameterizing Tests with a Data Provider

While suite parameters are useful for simple parameterization, they are not sufficient for creating data-driven tests with multiple test data values and reading data from external files, such as property files, CSV, Excel, or databases. In this case, we can use a Data Provider to supply the values need to test. A Data Provider is a method defined in the test class that returns an array of array of objects.  This method is annotated with the @DataProvider annotation. 

Let's modify the preceding test to use the Data Provider. Instead of using a single searchWord, we will now use three combinations of searchWords and expected items counts returned by the search. We will add a new method, named provider(), in the SearchTest class, as shown in following code, before the @BeforeMethod annotation:

public class SearchTest {

    WebDriver driver;

@DataProvider(name = "searchWords")
public Object[][] provider() {
return new Object[][]{
