TestNG BeforeSuite and AfterSuite

In this article, we will see testNG's annotations beforeSuite and afterSuite.

@BeforeSuite

@BeforeSuite is an annotation used to specify a method that needs to be executed before any test method in the suite.
This method is executed only once per suite.
For example, if you have a suite with multiple test classes, the @BeforeSuite method will be executed only once before the execution of any test method in any of the test classes.

@AfterSuite

@AfterSuite is an annotation used to specify a method that needs to be executed after all the test methods in the suite have been executed.
This method is also executed only once per suite.
For example, if you have a suite with multiple test classes, the @AfterSuite method will be executed only once after the execution of all the test methods in all of the test classes.

Example:

Consider three classes One, Two, and Three.

One:

package week4.day2;

import org.testng.annotations.Test;

public class One {

    @Test
    private void leafVillage() {
        System.out.println("Naruto");
    }

}

Two:

package week4.day2;

import org.testng.annotations.Test;

public class Two {

    @Test
    private void sandVillage() {
        System.out.println("Gara");
    }
}

Three:

package week4.day2;

import org.testng.annotations.AfterSuite;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.Test;

public class Three {

    @BeforeSuite
    private void akatsuki() {
        System.out.println("Itachi");
    }

    @Test
    private void leader() {
        System.out.println("Pain");
    }

    @AfterSuite
    private void mainAntagonist() {
        System.out.println("Madara");
    }

}

Now let us run these three classes with the testng.xml file.

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">  
<suite name="test_suite">  
<test name="One">  
<classes>  
<class name="week4.day2.One"/>  
</classes>  
</test> <!-- Test -->  
<test name="Two">  
<classes>  
<class name="week4.day2.Two"/>  
</classes>  
</test> <!-- Test -->  
<test name="Three">  
<classes>  
<class name="week4.day2.Three"/>  
</classes>  
</test>  
</suite> <!-- Suite -->

We can see here when three classes are run, and the three class has the @before and @after suite.
No matter what, running the methods with the annotation before and after any classes is prioritized.
That is what happened here.
