Test case generation is among the most labour-intensive tasks in software testing. It also has
a strong impact on the effectiveness and efficiency of software testing. For these reasons, it …

Symbolic PathFinder (SPF) is a software analysis tool that combines symbolic execution with
model checking for automated test case generation and error detection in Java bytecode …

Writing accurate numerical software is hard because of many sources of unavoidable
uncertainties, including finite numerical precision of implementations. We present a …

Roundoff errors cannot be avoided when implementing numerical programs with finite
precision. The ability to reason about rounding is especially important if one wants to …

Search-based testing can automatically generate unit test suites for object oriented code, but
may struggle to generate specific values necessary to cover difficult parts of the code …

Analyzing performance and understanding the potential best-case, worst-case and
distribution of program execution times are very important software engineering tasks. There …

We investigate the use of coverage-guided fuzzing as a means of proving satisfiability of
SMT formulas over finite variable domains, with specific application to floating-point …

Symbolic execution is a well-known program analysis technique for testing software, which
makes intensive use of constraint solvers. Recent support for floating-point constraint solving …

Abstract The Satisfiability Modulo Theory (SMT) problem over floating-point arithmetic is a
major hurdle in applying SMT techniques to real-world floating-point code. Solving floating …

In industry, software testing and coverage-based metrics are the predominant techniques to
check correctness of software. This paper addresses automatic unit test generation for …
