// Test is a base class for all tests.  It provides a command interface for
// running tests (run) as well as a data member for recording the name of 
// the test.
//
// Tests are constructed using the TEST macro.  TEST creates a subclass of
// Test and static instance of that subclass.  If you look at the constructor
// for the Test class, you'll notice that it registers the created object 
// with a global TestRegistry.  These features combine to make test creation
// particularly easy.

// Here is a collection of testing macros that can be used in the 
// bodies of tests.  CHECK tests a boolean expression and records
// a failure if the expression evaluates to false.  CHECK_LONGS_EQUAL
// and CHECK_DOUBLES_EQUAL compare longs and doubles respectively.
//
// To make this an industrial strength test harness, you should
// add equals macros for various low level types as you develop them.
// If, for instance, you have a daterange class, the ability to compare
// them directly and print out their values in the test output is 
// invaluable.
