.SYNOPSIS
|
|
Verifies the Module 06 challenge solutions.
|
|
|
|
.DESCRIPTION
|
|
Checks that all three reset scenarios have been completed correctly:
|
|
- soft-reset: Commit reset but changes remain staged
|
|
- mixed-reset: Commits reset and changes unstaged
|
|
- hard-reset: Everything reset and discarded
