Simple Calculator chunk 1 - Parsing Text

Goal

Using Test Driven Development, create a Parse class that will break down a simple 2-term calculator expression.

  1. Prove you can extract the terms of the expression.
  2. Prove you can extract the operation embedded in the expression.
  3. Ensure you have examples of GOOD and BAD input and have the class throw an exception where there are error.

Hints

  • Your expression should work with and without spaces.
  • The use of Regular Expressions is not required.
