// test.h: Base class for all tests
// This class encapsulates base functionality used by all tests. Some
// of this is fairly trivial (the test name, for example). One of the
// most important nontrivial functions is the use of the constructor
// to build a linked list of test objects; this eliminates the need to
// maintain a separate table of tests. This class also provides a
// flag for determining if a test has been run, which allows tests to
// invoke one another and make use of previous results without forcing
// tests to run multiple times. Finally, it provides a basic
// framework for recording a vector of results (which typically will
// vary depending on the drawing surface configuration or the
// particular type of drawing surface used).
// It is possible to derive test classes directly from this class.
// Most people will find it more convenient to use the BaseTest
// template class. See tbase.h for more information.
