XPS - Roman Numeral Conversion Solution

• I set up a services and common library to exemplify some n-tier architecture and facilitate TDD (which I tried to use for the most part).

• I ensured all aspects were working through tests before finally implementing a Console App to act as the UI.

• I looked online for Roman Numeral "Rules" - I have basic knowledge but needed a strong definition. https://byjus.com/maths/roman-numerals

• The best explanation for the rules was in the examples at the bottom;

• • break any number into its decimal units
• • (i.e. 1s, 10s, 100s, 1000s), convert each of these to a roman numeral and string them together

• Also thought about the parameters of the initial task and good error handing:

• • A number must be between 1 and 2000 (assumed inclusive) and not be a decimals or a negative.

• Room for improvements

• • Some of the test data rows are a bit much
    • Could load large data sets from a file to test against
• • Scalability
    • I'd liked to have put the template .Replace() functions in a loop,
