Checklist

• I reviewed the Contributing Guide.
• I performed a cursory search to see if the bug report is relevant, not redundant, nor in conflict with other tickets.

Describe the bug

• Similar to Remove use of "dummy" in variable names CF#105
  • Redundant use of the word "dummy" in some variables/text in the test code.

All test code variables are 'dummy' variables - no need to label them as such.

Expected behavior
Simplify test code by removing redundant qualifiers.
