This book constitutes the proceedings of the 17th International Colloquium on Theoretical Aspects of Computing, ICTAC 2020, which took place during November 30-December 4, 2020. The book deals with challenges in both theoretical aspects of computing and the exploitation of theory through methods and tools for system development.

Testing has steadily become more and more important within the development of software and systems, motivating an increasing amount of research aimed at tryingtosolvebothnewchallengesimposedbytheadvancementinvariousareas of computer science and long-standing problems. Testing has evolved during the last decades from an ad-hoc and under-exposed area of systems development to an important and active research area. The22ndInternationalConferenceonTestingSoftwareandSystems(ICTSS) involved the merger of two traditional and important events which have served the testing community as an important venue for discussing advancements in the area. Those events, namely, TestCom (the IFIP TC 6/WG 6.1 Inter- tional Conference on Testing of Communicating Systems), and FATES (Inter- tional Workshop on Formal Approaches to Testing of Software), together form a large event on testing, validation, and speci?cation of software and systems. They have a long history. TestCom is an IFIP-sponsored series of international conferences,previouslyalsocalledInternationalWorkshoponProtocolTestS- tems(IWPTS)orInternationalWorkshoponTestingofCommunicatingSystems (IWTCS).It is devoted to testing of communicating systems, including testing of communication protocols, services, distributed platforms, and middleware.

This book constitutes the thoroughly refereed post-conferenceproceedings of the 13th Brazilian Symposium on Formal Methods, SBMF2010, held in Natal, Brazil, in November 2010.The 18 revised full papers were carefully reviewed and selected from55 submissions. The papers presented cover a broad range of foundationaland methodological issues in formal methods for the design and analysisof software and hardware systems as well as applications in variousdomains.
