    DESCRIPTION

    This file (t_oomharness.cpp) contains all test framework related parts of

    this test module. Actual test cases are implemented in file 

    t_oomharnesscases.cpp.

    COomTestHarness is an example of test module implementation. This example

    uses hard coded test cases (i.e it does not have any test case

    configuration file).

    Example uses function pointers to call test cases. This provides an easy

    method to add new test cases.

    See function Cases in file t_oomharnesscases.cpp for instructions how to

    add new test cases. It is not necessary to modify this file when adding

    new test cases.

    To take this module into use, add following lines to test framework

    initialisation file:

# t_oomharness_stif

[New_Module]

ModuleName= t_oomharness_stif

[End_Module]

    Note: If OOM test case uses STIF Logger, then STIF Logger must be created

    with static buffer size parameter (aStaticBufferSize). Otherwise Logger 

    allocates memory from heap and therefore causes error situations with OOM 

    testing. For more information about STIF Logger construction, see STIF
