This change refactors the test procedure for TerminationPoint options.
Functionality is added to perform "update" tests for the TerminationPoint
options field. The existing test case for Create, Read & Delete of
TerminationPoint options is consolidated with the new update test procedure
resulting in one test containing 16 test cases for full CRUD coverage.
