                                                       Junit - Part 2


Test Data management is one of the essential things while doing test automation.We will see how parameterization is done in Junit. Both @RunWith and @ Parameter annotations are used to provide parameter values for the test. @Parameters will return a list and take an Object array as argument.

Parameterization using Junit is explained with the below example.


import java.util.Arrays;
import java.util.Collection;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;

@RunWith(value=Parameterized.class)
public class Test2 
{

private String Firstname,Lastname,Country;

public Test2(String Firstname, String Lastname,String Country)
{

this.Firstname=Firstname;
this.Lastname=Lastname;
this.Country=Country;
}

@Parameters
public static Collection<Object[]> TestData()
{

Object[][] TestData=new Object[][]{ {"sam","samm","Scotland"},{"wayne","rooney","England"},{"robin","van","Holland"}};
return Arrays.asList(TestData);

}


@Test
public void test() 
{
//Consider a scenario where you are testing registration functionality of  a website, by entering details of multiple users 

System.out.println("Parameterized Firstname is:"+Firstname);
System.out.println("Parameterized Lastname is:"+Lastname);

System.out.println("Parameterized country is:"+Country);
                 //Code to Enter Firstname,Lastname,Country and clicking on Register needs to written.
}

}

Running a Test suite that is a set of tests at a time is done in Junit by using @Suite and @RunWith parameters .

import org.junit.runner.RunWith;

import org.junit.runners.Suite;

@RunWith(Suite.class)

@Suite.SuiteClasses({

    Test1.class,

    Test2.class

})

public class TestSuite {

}
