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.
