Mutation testing is an established fault-based testing technique. It operates by seeding faults
into the programs under test and asking developers to write tests that reveal these faults …

Blockchain technologies have had a rather disruptive impact on many sectors of the
contemporary society. The establishment of virtual currencies is probably the most …

Applying mutation testing to test subtle program changes, such as program patches or other
small-scale code modifications, requires using mutants that capture the delta of the altered …

Context: When software evolves, opportunities for introducing faults appear. Therefore, it is
important to test the evolved program behaviors during each evolution cycle. However, while …

To effectively test program changes using mutation testing, one needs to use mutants that
are relevant to the altered program behaviours. In view of this, we introduce MuDelta, an …

Mutation testing is a powerful test adequacy assessment technique that can guarantee the
deployment of deeply scrutinized and more reliable Smart Contract code. However …

Mutation analysis is a powerful dynamic approach that has many applications, such as
measuring the quality of test suites or automatically locating faults. However, the inherent …

Mutation testing is a powerful test adequacy assessment technique that can guarantee the
deployment of more reliable Smart Contract code. Developers add new features, fix bugs …

Test amplification makes systematic changes to existing, manually written tests to provide
tests complementary to an automated test suite. We consider developer-centric test …

Mutation testing drives the creation and improvement of test cases by evaluating their ability
to identify synthetic faults. Over the past decades, the technique has gained popularity in …
