### Question:
FizzBuzz { public String anserFor(int number) { String answer = ""; if(isDivisibleBy(number,3)){ answer += "Fizz"; } if(isDivisibleBy(number, 5)){ answer += "Buzz"; } return answer.isEmpty() ? String.valueOf(number) : answer; }  String anserFor(int number);  }### Answer:
@Test public void shouldAnswerBuzzFor5() throws Exception { Assert.assertEquals(fizzBuzz.anserFor(5), "Buzz"); }
@Test public void shouldAnswerFizzFor6() throws Exception { Assert.assertEquals(fizzBuzz.anserFor(6), "Fizz"); }
@Test public void shouldAnswerBuzzFor10() throws Exception { Assert.assertEquals(fizzBuzz.anserFor(10), "Buzz"); }
@Test public void shouldAnswerFizzBuzzFor15() throws Exception { Assert.assertEquals(fizzBuzz.anserFor(15), "FizzBuzz"); }
@Test public void shouldAnswerFizzBuzzFor16() throws Exception { Assert.assertEquals(fizzBuzz.anserFor(16), "16"); }
@Test public void shouldAnswer1For1() throws Exception { Assert.assertEquals(fizzBuzz.anserFor(1), "1"); }
@Test public void shouldAnswer2For2() throws Exception { Assert.assertEquals(fizzBuzz.anserFor(2), "2"); }
@Test public void shouldAnswerFizzFor3() throws Exception { Assert.assertEquals(fizzBuzz.anserFor(3), "Fizz"); }
