    15 // Overview:

    16 // Test methods of CCirBuffer and CCirBuf template class.

    17 // API Information:

    18 // CCirBuffer, CCirBuf.

    19 // Details:

    20 // - Create a circular buffer, add integers to the circular buffer and check that 

    21 // they are added as specified.

    22 // - Verify Remove and Add work as expected.

    23 // - Check that all the added objects are removed.

    24 // - Create a circular buffer, add concrete data type object one, many at a time to the 

    25 // circular buffer and check that they are added as specified.

    26 // - Remove the concrete data type object one, many at a time from the circular buffer

    27 // and check that they are removed as expected.

    28 // - Check that all the added objects are removed.

    29 // - Create a circular buffer, add 8-bit unsigned character object one, many at a time

    30 // to the circular buffer and check that they are added as specified.

    31 // - Remove multiple 8-bit unsigned character objects from the circular buffer and 

    32 // check the added and removed objects are same.

    33 // - Create a circular buffer of unsigned integers, add single, multiple objects to the 

    34 // buffer and check that they are added as specified.

    35 // - Remove multiple objects from the circular buffer and check the added and removed 

    36 // objects are same.

    37 // - Create a circular buffer, add multiple signed integer objects to it, remove 

    38 // the objects and verify that the added objects are removed.

    39 // - Create a circular buffer, add integers to the circular buffer and check that 

    40 // they are added as specified.

    41 // - Verify Remove works as expected.

    42 // - Test whether the heap has been corrupted by all the tests.
