Adding test cases for:
=====================
0- writing a testcase for native method
1- code handle kardan reflection ro tamiz konam va masalan to yek class be esm reflection manager bezaram
3- reflection api ha baiad hengam error va exception ham raftar mamul ro dashte bashand
4- inke result invocation ha ham az tarigh holder gerefte beshe


Execution trace fragmentation
---------------------------------
1- comment kardan va tamiz kardan code
2- neveshtan yek class bara model kardan behtar execution trace k flatten nashode
3- neveshtan code inke vaghti execution trace yek method analyze mishe bara method haye nested ham execution trace shun ro analyz kone
4- gereftan bug inke reflection haye nested ro dorost analyz kone
