In order for a unit test module to successfully link and execute, it has
to have access to the test module's initialization function.
the module's initialization function is called only once during the execution
of the program, just before the test
module runner is run. By default, the Unit Test
Framework provides a default definition of initialization function.
The only thing you have to do is to instruct the framework in which translation

module as well as the master
test suite. The name to be assigned is specified by the value of the

There is practically no need to ever alter the default behavior of the test module's initialization function. The Unit Test Framework provides superior tools for performing customization tasks:

The default initialization function provided by the framework is defined with the following signature in the global namespace:
