Much of recent software-engineering research has investigated the naturalness of code, the
fact that code, in small code snippets, is repetitive and can be predicted using statistical …

Context: Automated fault localisation aims to assist developers in the task of identifying the
root cause of the fault by narrowing down the space of likely fault locations. Simulating …

Mutation testing is a powerful technique for assessing and improving test suite quality that
artificially introduces bugs and checks whether the test suites catch them. However, it is also …

Regression testing---rerunning tests on each code version to detect newly-broken
functionality---is important and widely practiced. But, regression testing is costly due to the …

Mutation testing is vital for ensuring software quality. However, the presence of equivalent
mutants is known to introduce redundant cost and bias issues, hindering the effectiveness of …

Context: Mutation testing is a powerful method used in software testing for various activities,
such as guidance for test case generation and test suite quality assessment. However, a …

The question of how to generate high-utility mutations, to be used for testing purposes, forms
a key challenge in mutation testing literature.% Existing approaches rely either on human …

In software testing, the quality of the test suite plays a very important role for not only the
effectiveness of the testing but also the quality assurance of software. Mutation testing is …

As a key phase in software testing and debugging, fault localization can significantly
influence the efficiency of fixing software faults. Among the various techniques, Mutation …

Approaches predicting the results of mutation testing by machine learning have been
proposed to reduce the cost of mutation testing. The predictive approaches based on PIE …
