Hi Anup,

Thank you so much for the review and for fixing these issues.

Now the documentation should be updated as well, correspondingly with 
the updates you made: currently, 'writing_tests.md' doc specifies the 
wrong Makefile variable name for the tests (libsbitests-... instead of 
libsbi-...). I'll fix it and send the patch today.

Kind regards,
