annotation that doesn't return Object[][]
or Iterator<Object>
. If another type is returned, TestNG throws an exception.
Example:
public class TestNgTest {
@DataProvider(name = "Languages")
List<String> getData() {
return List.of("Java", "Kotlin");
}
@Test(dataProvider = "Languages")
public void testData(String language) {
System.out.println(language);
}
}
