* Description: This file (DemoModule.cpp) contains all test 

* framework related parts of this test module. Actual test cases 

* are implemented in file DemoModuleCases.cpp.

*

* CTestModuleDemo is an example of test module implementation. This example

* uses hard coded test cases (i.e it does not have any test case

* configuration file).

*

* Example uses function pointers to call test cases. This provides an easy

* method to add new test cases.

*

* See function Cases in file DemoModuleCases.cpp for instructions how to

* add new test cases. It is not necessary to modify this file when adding

* new test cases.

*

* To take this module into use, add following lines to test framework

* initialisation file:

*

* # Demo module

* [New_Module]

* ModuleName= DemoModule

* [End_Module]
