// CwidecharclassapiBCTest::Case

// Returns a test case by number.

//

// This function contains an array of all available test cases 

// i.e pair of case name and test function. If case specified by parameter

// aCaseNumber is found from array, then that item is returned.

// 

// The reason for this rather complicated function is to specify all the

// test cases only in one place. It is not necessary to understand how

// function pointers to class member functions works when adding new test

// cases. See function body for instructions how to add new test case.

    * To add new test cases, implement new test case function and add new 

    * line to KCases array specify the name of the case and the function 

    * doing the test case

    * In practice, do following

    * 1) Make copy of existing test case function and change its name

    *    and functionality. Note that the function must be added to 

    *    widecharclassapiBCTest.cpp file and to widecharclassapiBCTest.h 

    *    header file.

    *

    * 2) Add entry to following KCases array either by using:

    *

    * 2.1: FUNCENTRY or ENTRY macro

    * ENTRY macro takes two parameters: test case name and test case 

    * function name.

    *

    * FUNCENTRY macro takes only test case function name as a parameter and

    * uses that as a test case name and test case function name.

    *

    * Or

    *

    * 2.2: OOM_FUNCENTRY or OOM_ENTRY macro. Note that these macros are used

    * only with OOM (Out-Of-Memory) testing!

    *

    * OOM_ENTRY macro takes five parameters: test case name, test case 

    * function name, TBool which specifies is method supposed to be run using

    * OOM conditions, TInt value for first heap memory allocation failure and 

    * TInt value for last heap memory allocation failure.

    * 

    * OOM_FUNCENTRY macro takes test case function name as a parameter and uses

    * that as a test case name, TBool which specifies is method supposed to be

    * run using OOM conditions, TInt value for first heap memory allocation 

    * failure and TInt value for last heap memory allocation failure.
