NEW QUESTION 35
A developer has implemented a class that calculates if a given date is a leap year. The definition for the leap year is given:
Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400.
– divisible by 4
– but not by 100
– years divisible by 400 are leap anyway
You have already thought about it and started with the first test class; the test class looks like (pseudo JavaScript used here):
// LeapYear.spec.js
describe(‘Leap year calculator’, () => {
it(‘should consider 1996 as leap’, () => {
expect(LeapYear.isLeap(1996)).toBe(true);
});
});
What would now be your next step to proceed as efficient as possible, to validate the correctness of the class above?
