### Question:
Force implements Direction, Updatable { public void setDirectionMinimum(Direction min) { directionMin = min; } Force();  Force(double fh, double fv);  Force(double fh, double fv, double velocity, double sensibility);  Force(Force force); static Force fromVector(double ox, double oy, double x, double y); void zero(); void setVelocity(double velocity); void setSensibility(double sensibility); void addDirection(double extrp, Direction direction); void addDirection(double extrp, double fh, double fv); void setDirection(Direction direction); void setDirection(double fh, double fv); void setDestination(double fh, double fv); void setDirectionMaximum(Direction max); void setDirectionMinimum(Direction min); double getVelocity(); double getSensibility(); boolean isDecreasingHorizontal(); boolean isIncreasingHorizontal(); @Override void update(double extrp); @Override double getDirectionHorizontal(); @Override double getDirectionVertical(); @Override int hashCode(); @Override boolean equals(Object object); @Override String toString();  }### Answer:
@Test void testSetDirectionMinimum() { final Force force = new Force(1.0, 2.0); force.setDirectionMinimum(new Force(3.0, 4.0)); force.update(1.0); assertForce(3.0, 4.0, 0.0, 0.0, force); }
