iSQI CTAL-ATT Exam - Topic 10 Question 25 Discussion

A developer has implemented a class that calculates if a given date is a leap year. The definitionfor the leap year is given:Every year that is exactly divisible by four is a leap year, except for years that are exactlydivisible 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 anywayYou have already thought about it and started with the first test class; the test class looks like(pseudo JavaScript used here):// LeapYear.spec.jsdescribe('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 correctnessof the class above?
D) First write code that makes this test case pass

iSQI CTAL-ATT Exam - Topic 10 Question 25 Discussion

Actual exam question for iSQI's CTAL-ATT exam
Question #: 25
Topic #: 10
[All CTAL-ATT Questions]

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?

I’m surprised this isn’t more straightforward. Why complicate it?

Nah, I’d go with B. Need to implement the logic first.

I think option A is the best choice. More tests = better coverage!

I think we should focus on making the current test pass before moving on to other cases, just to ensure our base case is solid.

I feel like I saw a similar question where we had to make a test fail first to see if our logic was correct. That could be a good approach.

I'm not entirely sure, but I think we might need to implement the logic for the leap year calculation before adding more tests.

I remember we discussed how important it is to cover all edge cases in our tests, so maybe I should write additional test cases first.

I'm feeling pretty confident about this one. The requirements are clear, and the test case is a good starting point. I think I'll follow the test-driven development approach and write some more comprehensive test cases before diving into the implementation.

This seems pretty straightforward to me. I'll just start by writing the code to make the existing test case pass, and then build out the implementation from there. No need to overcomplicate things.

Okay, I think I've got a good strategy here. I'll start by writing a test case that checks for a year that's not a leap year, like 1997. That way I can make sure the implementation is handling all the edge cases correctly.

I'm a bit confused about the requirements here. The question mentions a class that calculates leap years, but I don't see any code for that class. Should I start by writing the implementation first, or focus on the test cases?

Hmm, this looks like a good opportunity to practice test-driven development. I think I'll start by writing some more test cases to cover the different scenarios for leap years, like years divisible by 100 and 400.

Option B looks promising, as it includes the "interfaces" and "interface" components in the URI, which seem relevant to the question.

This seems like a pretty straightforward customer success question. I think the key is to focus on what the next logical step would be after the customer has finalized their solution planning and is about to deploy.

Hmm, I'm a bit unsure about this one. There are a few different Prisma Cloud documentation options mentioned. I'll need to carefully review each one to determine which one is most relevant for the specific task of querying user permissions.
