TestNG Method Overriding: Earlier, we have seen how we can achieve method overloading in a TestNG class, and similarly, in this post, we are going to see how we can make method overriding in a testNG class.
As we all know about method overriding is nothing but creating a method in child class which is already a similar method in the parent class is called method overriding. If you want to know the complete post about this, you can use this method overriding the link.
TestNG Method Overriding Example
So let us discuss how we can achieve method overriding in Java:
First Creat a superclass like below:
package InheritanceInTestNG;
import org.testng.annotations.Test;
public class SuperTestNgClass
{
@Test
public void superTestNgMethod()
{
System.out.println(“Super testng method”);
}
@Test
public void superTestNgAnotherMethod()
{
System.out.println(“Super testng Another method”);
}
}Create another child class like below:
package InheritanceInTestNG;
import org.testng.annotations.Test;
public class SubTestNGClass extends SuperTestNgClass
{
// Overriding super class testng methods
@Test
public void superTestNgMethod()
{
System.out.println("Super testng method overrriden in sub class");
}
// Method of sub class
@Test
public void subTestNgMethod()
{
System.out.println("Sub testng method");
}
}Now create a testng.xml file for the child class and run that. If you take a look at the output, then you will find out that it will execute all the methods of child class with the overridden method.
In our earlier discussion, we have seen that TestNG prioritizes and executes the test cases if we run separately both super and subclasses. But if we override, then all methods of subclass with the overridden method will be executed, but the parent method of superclass will be ignored.
