Fixed failing test about assert with message

Learned that the assert method is able to have a message about the assertion

[#65851494]
added a fill-in value to get an assert to work.

* This assert used a logic expression to look for equality.

[#65851494]
filled in another blank

* This time learned there are special asserts.  In this case the
  assert was call assert_equals that had two arguments

[#65851494]
Filled in one more blank

* This one still used the assert_equal, and used constants
