// Description:

// e32test\buffer\t_buf.cpp

// Overview:

// Test methods of the TBuf16, TBuf8, TBuf template class.

// API Information:

// TBuf16, TBuf8, TBuf.

// Details :

// - Create some 16 bit modifiable descriptors, 8 bit modifiable descriptors

// of fixed length, Build-independent modifiable descriptors, initialize 

// with different strings and check for

// - Comparison operators,

// - Property access methods,

// - Fill & swap methods,

// - Conversion methods,

// - Comparison methods,

// - Pattern Matching methods,

// - Pattern Locating methods,

// - Copying methods, 

// - Find, FindC, FindF methods,

// - Repeat, Trim, TrimLeft, TrimRight, Insert, Delete, Left,

// Right, Mid methods,

// - Formatting methods,

// - Replace methods are as expected.

// - Construct some descriptors with buffer length, string and buffer reference and

// verify that they are created successfully.

// - Test assignment operators and comparison operators for different descriptors.

// - Initialize some descriptors and check descriptors' maximum length, length and 

// size are as expected. 

// - Check Fill and Swap methods are as expected.

// - Test Fold, Collate, LowerCase, UpperCase methods are as expected.

// - Test Comparison methods are as expected.

// - Test pattern matching for simple string, wild cards with collated comparison. Verify that the 

// return value is KErrNotFound when pattern doesn't match.

// - Check Locating methods by searching character in forward and backward direction and 

// verify the return value is KErrNotFound when unavailable character is searched.

// - Check copying strings and converting those into lower and upper case strings are

// as expected.

// - Check Find methods by searching string and verify the return value is KErrNotFound when 

// unavailable string is searched.

// - Check Repeat, Trim, Insert and Delete methods are as expected.

// - Check the formatting operations are as expected.

// - Check integer to decimal character representation is as expected.

// - Check integer to character representation with different number system is as expected.

// - Check string formatting with variable parameter list is as expected

// - Check Replace method by replacing string at different places in a string is as expected.

// - Check the conversion of real numbers, extended precision real numbers into string

// format is as expected.

// - Check Format and FormatList methods are as expected.

// - Check Format of TReal is as expected.

// - Check the non-leaving and leaving descriptors overflow handlers are as expected. 

// Platforms/Drives/Compatibility:

// All 

// Assumptions/Requirement/Pre-requisites:

// Failures and causes:
