You have to create an instance of the class ‘testing’. Only that class has the overridden method e.g:

 public class Test : MonoBehaviour
 {
     void Start()
     {
         Debug.Log("Started");

         var testingInstance = new testing();
         testingInstance.test1();
     }
 
     public virtual void test1(){}
 }
 
 public class testing : Test
 {
     public override void test1()
     {
         Debug.Log("Override called");
     }
 }

However, you might not want to have ‘Test’ inherit from Monobehaviour, because it’s not preferable to create instances of monobehaviour classes manually.
