i need help fixing my code. assignment: Using a combination of Boundary Analysis and Equivalence Partitions create the set of test cases to test the function:

bool IsLeap$($int year$)$

Which test whether the year is a leap year as per the rule of the Gregorian Calendar.

Name your Test Cases TestMethodX where X is a counter starting from $1.$

Notes:

Using this will generate a test cases for all the boundaries in each partition and their corresponding $+/-1$ for a total of $15$ test cases.

Even though you may implement the function to test your code locally, only submit the test cases to the system. code: using Microsoft.VisualStudio.TestTools.UnitTesting;

using System;

using System.Collections.Generic;

The student's TestMethod$3$ is testing a case where the year is divisible by $100$ but not by $400.$ This is an equivalence partition, but the test is not covering the correct boundary. The student should test a year that is divisible by $100$ and not by $400,$ but is not the first year in a new century.

Your student's code is missing a test case for a year divisible by $100$ but not by $400.$ They should also check if their implementation is correctly handling such years.

Make sure to test all boundary cases and their corresponding $+/-1$ values. Check if the test cases cover all possible scenarios.

The student's code seems to be missing some test cases. Make sure to include test cases for all the boundaries in each partition and their corresponding $+/-1$ for a total of $15$ test cases. Also, check if the student's implementation of the IsLeap function is correct.

The student's test cases are missing some important boundary cases. Consider the year just below the leap year divisible by $4$ and the year just above the year divisible by $100$ but not by $400.$ These cases are not covered in the student's test cases.
