Note- Include those methods in testng.xml which you want to execute.


For ex- inside com.CC.scripts.Login class there are 100 test cases but you want to execute only 3 methods- at_loginValid, at_loginBlank and at_loginInValid. In that case you can edit your xml as below-

<suite name=”Suite” parallel=”none”>
<test name=”Test”>
<classes>
<class name=”com.CC.scripts.Login”>
<methods>
<include name=”at_loginValid”></include>
<include name=”at_loginInValid”></include>
<include name=”at_loginBlank”></include>
</methods>
</class>
</classes> 
</test> 
</suite>

Login class- Here hello method will not execute by using above testng.xml

package com.CC.scripts;
import org.testng.annotations.Test;

public class Login {
@Test
public void at_loginValid(){
System.out.println(“at_loginValid”);
}
@Test
public void at_loginInValid(){
System.out.println(“at_loginInValid”);
}
@Test
public void at_loginBlank(){
System.out.println(“at_loginBlank”);
}
@Test
public void hello(){
System.out.println(“hello”);
}
}
