/** When adding new tests try to follow the test execute path currently taken by existing tests.

A typical test case follows this logic flow though the code:

doTestStepL() is called, where the required clock admin is set, which in turn causes the admin notification function
OnSettingUpdateEvent() to be called, from which the test starts (some tests will end here also).

Then from OnSettingUpdateEvent() a async operation is fired, which results in the RunL() being called, from here the test will
come to a end or continue with a further cycle of RunL().

During the test CheckForTestHalt() will be called to determine is the test has finished, which done as a result of
the correct test flags being set.
