We COULD define the parameters in the testng.xml file and then reference those parameters in the source files.

Create a JAVA test class, say, ParameterizedTest.java and add a test method say parameterizedTest() to the test class. This method takes a STRING as input parameter. Add the annotation @Parameters(“browser”) to this method.

1. // TestNG Interview Questions
2. public class ParameterizedTest {
3. @Test
4. @Parameters("browser")
5. public VOID parameterizedTest(String browser){
6. if(browser.equals("firefox")){
7. System.out.println("Open Firefox Driver");
8. }else if(browser.equals("CHROME")){
9. System.out.println("Open Chrome Driver");
10. }
11. }
12. }

The parameter would be passed a value from testng.xml, which we will see in the next step.

We could set the parameter using the below syntax in the testng.xml file. 

<parameter name="browser" value="firefox"/>

Here, name attribute represents the parameter name and value represents the value of that parameter.
