Marcos Lordello Chaim obtained BSc (1987), MSc (1991) and PhD (2001) degrees in Electrical Engineering from the State University of Campinas, Campinas, Brazil. From 1990 to 1992, he was assistant professor at São Paulo State University (UNESP), São José do Rio Preto, Brazil. After leaving UNESP, he worked at Embrapa Information Technology where he developed software for the agribusiness domain until 2005. Since then, he is faculty member of the School of Arts, Sciences and Humanities (EACH), University of São Paulo (USP), São Paulo, Brazil. His research interests lies on the following topics: software testing, debugging, and maintenance, software development methods, empirical software engineering, programming languages, and information systems education.

Debugging is the activity responsible for locating and correcting defects generated during the development of programs. It is understood as the corollary of a successful test since it starts from a test that reveals the presence of defects. Because of this relationship between testing and debugging, heuristics were developed to identify pieces of code most likely to contain defects from c…
Software testing is one of the most time-consuming activities performed by programmers. Although effective testing techniques --- such as data-flow testing --- exist, testing is often carried out in "ad hoc" way. One of the problems is the cost to instrument programs in order to determine the coverage of the tests in real settings. In real settings, programs might execute millions of stat…
Data-flow (DF) testing aims at achieving comprehensive structural evaluation of programs. It requires tests that traverse a path in which the definition of a variable and its subsequent use, i.e., a definition-use association (dua), is exercised or covered. However, DF testing has scarcely been adopted in industry because it is considered too costly. We plan to investigate the subsumption…
