Given Below is a test module with extended transaction class,
- $test$plusargs ("TEST1") arguments are applied run-time through Makefile e.g +TEST1 with vsim command.
- For TEST2, After building all transactors, we need to assign child/extended transaction handle to transaction handle in Generator Class, so as to create extended transaction using parent/base class handle.
