Call Super Anti-pattern

The Call Super anti-pattern shows up occasionally in object oriented code.


Any time an inherited class overrides a method and is required to call super() first, that is a case of this anti-pattern. It is not a good idea to require something else being called first.

public class TestCase

 public void setup() {
   doStuff();
 }

public class TestCaseOne extends TestCase

 public void handle() {
   super.setup();
   setupForTCOne();
 }
