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();
  }
