DataProvider without name attribute

In such cases by default it will take method name as a dataprovider name for name attribite.

Lets create Java class

package testngexp;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

publicclassdpwithoutname {
@Test(dataProvider="getLogindata")
publicvoid TestMethod(String username,String pwd){
System.out.println("Logged in User Name-->"+username);
System.out.println("Logged in Passwrod-->"+pwd);
}
@DataProvider
public Object[][] getLogindata(){
returnnew Object[][]{
{"rana","ranajani"},
{"rja","jani"},
{"kabali","linga"}
};
}
}

TestNG.xml

<testname="Test1">

</classes>
</test><!-- Test -->

Results


Here, we are not given any name for @DataProvider, in such cases we will use method name as a dataprovider name(ex: getLogindata)
