Name
TestDecorator
Description
The class
TestDecorator
(see Figure C-19) allows
the functionality of a Test to be extended without
subclassing it. TestDecorator implements the
Test interface and thus can be run like any other
Test. When constructed, it takes a reference to
another Test that it
“decorates,” or wraps. A
TestDecorator modifies the decorated
Test by performing other operations before or
after running it.
The classes RepeatedTest and
TestSetUp are subclasses of
TestDecorator and provide practical examples of
its usage. The base implementation of
TestDecorator simply is a wrapper for a
Test and does not change its operation.
TestDecorator belongs to the namespace
CppUnit. It is declared and implemented in
extensions/TestDecorator.h.
