Week1/day1/ex8 - maxNum

[jotapero]

Exercise is not explicit, example function and summary don't explain what the tests intend. Program wants a function that takes maximum of 3 numbers, but tests compare only the highest of the 3 arguments.

void main() {
  group('maxNum', () {
    for (int i = 0; i < 50; i++) {
      Random rnd = new Random();
      int first = -100 + rnd.nextInt(200);
      int second = -100 + rnd.nextInt(200);
      int third = -100 + rnd.nextInt(200);

// this test checks for the maximum value on the list

      test('maxNum(${first}, ${second}, ${third})', () {
        expect(student.maxNum(first, second, third),
            equals([first, second, third].reduce(max)));
      });
    }
  });
}

What is the purpose of the exercise?

[sakenism]

The purpose was to let students know about ternary operators, and their existence in dart. It is not super necessary concept, but we wanted them to know about it.
