Empirical research on concurrent software testing: A systematic mapping study.

Background: Concurrent software testing is a costly and difficult task, especially due to the exponential increase in the test sequences caused by non-determinism. Such an issue has motivated researchers to develop testing techniques that select a subset of the input domain that has a high probability of revealing faults. Academics and industrial practitioners rarely use most concurrent software testing techniques because of the lack of data about their applicability. Empirical evidence can provide an important scientific basis for the strengths and weaknesses of each technique to help researchers and practitioners choose concurrent testing techniques appropriate for their environments.
