th The 20 anniversary of the IFIP WG6. 1 Joint International Conference
on Fonna! Methods for Distributed Systems and Communication Protocols
(FORTE XIII / PSTV XX) was celebrated by the year 2000 edition of the
Conference, which was held for the first time in Italy, at Pisa, October
10-13, 2000. In devising the subtitle for this special edition --'Fonna!
Methods- Implementation Under Test' --we wanted to convey two main
concepts that, in our opinion, are reflected in the contents of this
book. First, the early, pioneering phases in the development of Formal
Methods (FM's), with their conflicts between evangelistic and agnostic
attitudes, with their over- optimistic applications to toy examples and
over-skeptical views about scalability to industrial cases, with their
misconceptions and myths . . ., all this is essentially over. Many FM's
have successfully reached their maturity, having been 'implemented' into
concrete development practice: a number of papers in this book report
about successful experiences in specifYing and verifYing real
distributed systems and protocols. Second, one of the several myths
about FM's - the fact that their adoption would eventually eliminate the
need for testing - is still quite far from becoming a reality, and,
again, this book indicates that testing theory and applications are
still remarkably healthy. A total of 63 papers have been submitted to
FORTEIPSTV 2000, out of which the Programme Committee has selected 22
for presentation at the Conference and inclusion in the Proceedings.
