The Call Super Anti-pattern

What is the Call Super Anti-pattern

The Call Super anti-pattern shows up occasionally in object oriented code. Any time an inherited class overrides a method but is still required to call super() at some point during the method, then that is a case of this anti-pattern. It is not a good idea to require something else being called at some point during the method.

Examples

public class TestCase
  public void setup() {
    doStuff();
  }
public class TestCaseOne extends TestCase
  public void handle() {
    super.setup();
    extraSetupForTestCaseOne();
  }
