Question 2 (5 points):
The following Java method processes an employee's salary, calculating bonuses and deductions based on years of service, basic salary, and performance rating. Your task is to design test cases using JUnit to validate this method. Apply equivalence partitioning and boundary value analysis for the input parameters. Additionally, ensure that your test cases cover all four branches of the code for 100% code coverage.

Sample JUnit Test Class for Completion
The following is a partially written JUnit test class for the EmployeeSalary Test method. Students are tasked with completing this class by adding the required test cases to achieve full equivalence partitioning, boundary value analysis, and branch coverage for the calculateSalary method.
