=================

TestStringClass
|
|
|
|
This is a fairly rigorous test of the str class's functionality.
|
|
Because of the fairly global and subtle ramifications of a bug occuring
|
|
in this class, it should be run after any changes to the class.
|
|
Add more tests as functionality is changed. Tests should include
|
|
any possible bounds violation and NULL data tests.
