// Description:

// e32test\buffer\t_bflat.cpp

// Overview:

// Test all aspects of the CBufFlat class.

// API Information:

// CBufFlat.

// Details:

// - Test all the operations of the class and see if methods are implemented -- 

// including NewL, Reset, Size, Set Reserve, InsertL, Delete, Ptr, Read, Write and Compress.

// - Test CBufFlat constructor is as expected.

// - Insert data into the flat storage dynamic buffer and verify that InsertL method

// is as expected.

// - Delete all data in buffer using Reset() method  and check size is zero.

// - Test Ptr, Free, Size, Backptr and SetReserveL methods work as expected.

// - Insert data into the buffer, delete some data from the beginning, middle, end and

// check for data is as expected. 

// - Verify the data in the buffer before and after Compress and Read methods is as expected.

// Platforms/Drives/Compatibility:

// All 

// Assumptions/Requirement/Pre-requisites:

// Failures and causes:

// Base Port information:
