The adoption of agile approaches has put an increased emphasis on testing, resulting in
extensive test suites. These suites include a large number of tests, in which developers …

Testing involves examining the behaviour of a system in order to discover potential faults.
Given an input for a system, the challenge of distinguishing the corresponding desired …

To find defects in software, one needs test cases that execute the software systematically,
and oracles that assess the correctness of the observed behavior when running these test …

Context As a result of automated software testing, large amounts of software test code
(script) are usually developed by software teams. Automated test scripts provide many …

Rather than tediously writing unit tests manually, tools can be used to generate them
automatically-sometimes even resulting in higher code coverage than manual testing. But …

To assess the quality of test suites, mutation analysis seeds artificial defects (mutations) into
programs; a non-detected mutation indicates a weakness in the test suite. We present an …

Context: One of the critical phases in the software development life cycle is software testing.
Testing helps with identifying potential bugs and reducing maintenance costs. The goal of …

Automated generate-and-validate program repair techniques (G&V techniques) suffer from
generating many overfitted patches due to in-capabilities of test cases. Such overfitted …

Unit testing could be used to validate the correctness of basic units of the software system
under test. To reduce manual efforts in conducting unit testing, the research community has …

Refactorings are behavior-preserving program transformations that improve the design of a
program. Refactoring engines are tools that automate the application of refactorings: first the …
