This book constitutes the refereed proceedings of the 7th International Conference on Test and Proofs, TAP 2013, held in Budapest, Hungary, in June 2013, as part of the STAF 2013 Federated Conferences. The 12 revised full papers presented together with one tutorial were carefully reviewed and selected from 24 submissions. The papers are devoted to the synergy of proofs and tests, to the application of techniques from both sides and their combination for the advancement of software quality. The papers are related to the following topics: test generation; model-based testing and mutants; declarative debugging; and tool testing.

This book constitutes the refereed proceedings of the 19th IFIP TC 6/WG 6.1 International Conference on Testing Communicating Systems, TestCom 2007, and the 7th International Workshop on Formal Approaches to Testing of Software, FATES 2007, held in Tallinn, Estonia in June 2007.

The 24 revised full papers presented together with 1 invited talk were carefully reviewed and selected from initially 61 submissions to both events. The papers address all current issues in testing communicating systems and formal approaches in testing of software, ranging from classical telecommunication issues to general software testing. They were presented in 8 multipart sessions coverering automata-based testing, practical experiences, system testing, modular systems, and test quality.
