Little Kata in java to practise easily the implementation of Adapter pattern
We have an application where you can create a song or a fly lesson from Birds Canary and Sparrow.
We need to add new “birds” a Bat, MagicPotato and Duck , but this classes can not be modify and they do not have the methods necessary to use our existing implantation.
You need to use the Adapter Pattern to find a solution.
You have two different projects
AdapterPatternBefore Base code of the KATA
AdapterPatternAfter Solution of the Kata
Eager to learn!!
Test that show how you can create a song
@Test
public void make_ALL_Birds_create_a_Melody() {
Bird isCaptain = new Sparrow();
Bird canary = new Canary();
String song = canary.sing()+" "+isCaptain.sing();
Melody melody = new Melody(song);
Melody melodyExpected = new Melody("Melodious PIO PIO Chirp Chirp");
melody.printMelody();
assertEquals(melodyExpected.melody,melody.melody);
}
Test that show how you can create a Fly Lesson
@Test
public void make_ALL_birds_teach_Flylessons(){
Bird isCaptain = new Sparrow();
Bird canary = new Canary();
String lesson =canary.fly()+" "+isCaptain.fly();
FlyTime flylesson = new FlyTime(lesson);
FlyTime flyLessonExpected = new FlyTime("Flying like a canary Flying to steal your Bread");
flylesson.printFlyLessons();
assertEquals(flyLessonExpected.flyLesson,flylesson.flyLesson);
}
