+ Class: COomTestHarness
+
+ Method: Case
+
+ Description: 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.
+
+ Parameters: const TInt aCaseNumber :in: Test case number
+
+ Return Values: const TCaseInfo Struct containing case name & function
+
+ Errors/Exceptions: None
+
+ Status: Proposal
+

+ * 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
+ * OOMHard.cpp file and to OOMHard.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
