    13 // Description:
    14 // e32test\buffer\t_varray.cpp
    15 // Overview:
    16 // Test variable record length array classes.
    17 // API Information:
    18 // CArrayVarFlat, CArrayVarSeg.
    19 // Details:
    20 // - Create an array of variable length text using a flat dynamic & segmented
    21 // buffer and verify that:
    22 // - number of elements held in the array is 0.
    23 // - array is compressed and reset as expected.
    24 // - the elements of the array are sorted as expected.
    25 // - insertion of a text character into the array at specified position 
    26 // and length of the array is as expected.
    27 // - return value is 0 when available element is searched using sequential 
    28 // search technique within the array.
    29 // - removal of first element from the array is successful.
    30 // - number of elements held in the array is 1 after appending a single 
    31 // element at the end of empty array.
    32 // - insertion of a single element with specified key is successful.
    33 // - the element is found when searched using binary search technique
    34 // - KErrAlreadyExists is returned if an element is inserted with the same 
    35 // key already exists within the array.
    36 // - Create an array of variable length text character implemented using a flat 
    37 // dynamic & segmented buffer.
    38 // - append some strings onto the end of the array, check the contents and 
    39 // number of elements held in the array are as expected.
    40 // - insert some strings and verify that the change in the content of array 
    41 // and number of elements held in the array are as expected.
    42 // - remove a single, multiple elements from the array and verify that the 
    43 // Delete method is as expected.
    44 // - Create an array of variable length text character contained within a flat 
    45 // dynamic & segmented buffer.
    46 // - append some strings of specified length onto the end of the array, compress 
    47 // the array and verify that the number of elements held in the array is as specified.
    48 // - insert a string at specified location, check the contents and reset the array.
    49 // - append some strings at the end, insert some strings at specified position, 
    50 // compress the array and verify that content, number of strings in the array 
    51 // are as expected.
    52 // - test that the number of elements and contents of the array are sorted as expected.
    53 // - verify the correct position of the element and return value is zero when 
    54 // an element is found using binary, sequential search technique and nonzero 
    55 // if not present in the array.
    56 // - insert some strings at the specified location and check that correct position
    57 // is returned when searched using binary search technique.
    58 // - Create an array of variable length integer contained within a flat dynamic &
    59 // segmented buffer.
    60 // - insert some elements with same key which is already present within the array 
    61 // and check that KErrAlreadyExists is returned. 
    62 // - Test whether the heap has been corrupted by all the tests.
