Guiding device usage: This App makes it a Snap

If you are a parent you might desire to be aware of what your children are doing on their electronic devices, so that you can provide guidance to help them develop good habits. In that, you would not be alone: "Surveys, including by the Pew Research Center, have found that two-thirds of parents check their children’s digital footprints..."*

Let me cut to the chase.

The assumptions are the details of external factors that influence a unit's operation. It is important to call out the external assumptions to keep those distinct from the functionality of the unit itself. If a developer tries to write a unit test without modeling the assumptions, when they attempt to exercise the unit of code, they will also be exercising other cod…
