test.ps1

<#
.SYNOPSIS
    Test the solution.
.DESCRIPTION
    Test the solution to verify correctness. This script verifies that:
    - The config.json file is correct
    - The generators project builds successfully
    - The example implementations pass the test suites
    - The refactoring projects stub files pass the test suites
.PARAMETER Exercise
    The slug of the exercise to verify (optional).
.EXAMPLE
    The example below will verify the full solution
    PS C:\> ./test.ps1
.EXAMPLE
    The example below will verify the "acronym" exercise
    PS C:\> ./test.ps1 acronym
