Parameterized Boundary Testing Reference

Multiple Boundary Cases

Off-By-One Testing

  })
  void shouldValidateRangeBoundaries(int value, boolean expected) {
    boolean inRange = value >= 0 && value <= 100;
    assertThat(inRange).isEqualTo(expected);
  }

  @Test
  void shouldHandleArrayIndexOffByOne() {
    int[] array = {1, 2, 3};

    assertThat(array.length).isEqualTo(3);
    assertThat(array[0]).isEqualTo(1);
    assertThat(array[array.length - 1]).isEqualTo(3);
  }
