7binary / salary

PHP challenge with Symfony4.3: Docker, Entity, Repository, Services, ExpressLanguage, PhpUnit

Technical Challenge

Please, keep in mind OOP, software design patterns, code architecture, tests and accuracy in implementation during developing. Here you need to build an application which can calculate the salary of employees. We need to have an expandable system of bonuses or deductions.

Explanation

• Country Tax for salaries is 20%
• If an employee older than 50 we want to add 7% to his salary
• If an employee has more than 2 kids we want to decrease his Tax by 2%
• If an employee wants to use a company car we need to deduct $500

Situation

• Alice is 26 years old, she has 2 kids and her salary is $6000
• Bob is 52, he is using a company car and his salary is $4000
• Charlie is 36, he has 3 kids, company car and his salary is $5000

CODE

Core logic of calculations are inside services.

• TaxCalculator: /symfony/src/Service/TaxCalculator.php
• SalaryCalculator: /symfony/src/Service/SalaryCalculator.php

Tests to check calculators services.

• TaxCalculatorTest: /symfony/tests/Service/TaxCalculatorTest.php
• SalaryCalculatorTest: /symfony/tests/Service/SalaryCalculator.php
