Matthias made the following comments based on a personal project of his:

I don't really have enough spare time to make a nice release of SymUnit, still I think it might be useful for you to receive the input I mentioned when we met the last time. So here we go:

1) As from UIQ 3.1 you could also use the SVG, however the mbm would be backward compatible to 3.0:
CAPTION_AND_ICON_INFO
{
caption = "SymbianOSUnit";
number_of_icons = 3;
icon_file = "\\Resource\\Apps\\SymbianOSUnit.svg";
}
2) For this kind of testing you definitely do not want to have the fancy memory checking/freeing mechanism and therefore you should
remove (this will also cause the memory size-checking to return the wrong non-useful value).
// STATICLIBRARY qikalloc.lib
// LIBRARY qikallocdll.lib

3) I think a namespace should be ended by a semicolon
namespace TestUtils
{

TBool WaitForActiveSchedulerStopL( TInt aTimeoutSeconds );
enum TThreadWaitOption { EWaitForExit, ENoWaitForExit };
void RunInSeparateThreadL( const TCallBack& aFunctionToRun, TThreadWaitOption aWaitForExit = EWaitForExit );
}

4) Ease your life by changing the small testgen.bat script. What's wrong in including ALL header files? Thereby you do not need to edit the script anymore
