Orthodox

Description

The template Orthodox (see Figure C-9) is a subclass of TestCase. When specialized for a class, it tests the class for “orthodoxy,” represented by the following conditions:

• The class has a default (no argument) constructor

• The class has equality (==) and inequality (!=) operators

• The class has an assignment (=) operator

• The class has a negation (!) operator

• The class has a copy constructor

The test verifies not only that ClassUnderTest has these operations, but also that the operations’ semantics are correct. For example, double negation should result in equality.

The main purpose of Orthodox is to serve as a working example of a templated test case.

Orthodox belongs to the namespace CppUnit. It is declared and implemented in extensions/Orthodox.h.
