Testing $($Verifying System Performance and Accuracy$)$

To ensure the EmployeeManagementSystem operates correctly and manages em$-$ ployee records efficiently as intended, a structured testing process is essential. This process, involving the use of an input file to test the system$$s functionali$-$ ties, ensures comprehensive evaluation.

Testing Procedure

Input File: An input file is provided containing a series of commands de$-$ signed to simulate the different operations the EmployeeManagementSys$-$ tem can perform, such as adding employees, approving leaves, changing employee states, and more.

Execution: The testing should be performed within the main method of your system. By running your system with this input file, the Employ$-$ eeManagementSystem will process each command sequentially, mirroring real$-$world usage scenarios.

Output File: Concurrently, an output file will be generated, containing the results of processing all commands from the input file. This file serves as a tangible record of the system$$s responses to each operation.

Expected Outcomes: The essence of testing lies in comparing the actual output generated by your system against the expected output detailed in the testing documentation. A match between these outputs indicates that the system functions correctly and as expected, affirming its reliability in managing employee records accurately.

Important Note on Bonus Calculation

For the purpose of simplification and to ensure consistency in testing, the bonus percentages for each employee type have been predefined as follows:

$$ Designer: A bonus rate of $0\mathrm{.}10(10\%)$ of their salary.

Developer: A bonus rate of $0\mathrm{.}12(12\%)$ of their salary.

$$ Manager: A bonus rate of $0\mathrm{.}15(15\%)$ of their salary.

When calculating bonuses for each employee type, the system must apply these specific rates. This standardization aids in validating the system$$s functionality, particularly its accuracy in processing financial calculations according to defined criteria.
