Use the AddKeyValuePair member function to specify the information you want to store in the key.
void TSampleObjectBaseTest::CopyInfo(TDictionaryOf<TStandardText,TText>& infoDict) const
{
TTest::CopyInfo;
TAllocationHeap heap(&infoDict);
// You can define your own keywords
static const TStandardText kSampleTestInformationKey("Sample Info");
// Developer defined key
infoDict.AddKeyValuePair(new(heap) TStandardText(kSampleTestInformationKey), new(heap) TStandardText(
"This is the way to add your test information"));
