10 * Orthodox performs a simple set of tests on an arbitary
11 * class to make sure that it supports at least the
12 * following operations:
13 *
14 * default construction - constructor
15 * equality/inequality - operator== && operator!=
16 * assignment - operator=
17 * negation - operator!
18 * safe passage - copy construction
19 *
20 * If operations for each of these are not declared
21 * the template will not instantiate. If it does
22 * instantiate, tests are performed to make sure
23 * that the operations have correct semantics.
24 *
25 * Adding an orthodox test to a suite is very
26 * easy:
27 *
28 * public: Test *suite () {
29 * TestSuite *suiteOfTests = new TestSuite;
30 * suiteOfTests->addTest (new ComplexNumberTest ("testAdd");
31 * suiteOfTests->addTest (new TestCaller<Orthodox<Complex> > ());
32 * return suiteOfTests;
33 * }
34 *
35 * Templated test cases be very useful when you are want to
36 * make sure that a group of classes have the same form.
37 *
38 * see TestSuite
