Coding challenge Sales Taxes solution in NetCore 3.1

Description of solution

• Was used swagger UI to test differents inputs
• Was used repository pattern emulating the use of DB with EF in memory
• Was created an unit test for the input of challenge and 3 tests more

Important

• I assumed that all product must have an unique code, so if one code is used more that onces, the system get the max price of boths to calculate the tax
• The departmentId property must exist in system, so the first step is run Endpoint of Departments that get the information from DB.
