Add new unit-tests for modules

[msmith-ccom]

Issue: Portions of the code base are not covered by either unit-tests nor example test scripts [#15 ]. To shift back towards a test driven development cycle, the coverage of the current code base must be increased

Objective: Write new unit-tests for modules not currently covered within the test directory or issue 15.

Tasks:

• Identify portions of the code base not covered
• Write unit-tests for uncovered modules
