Refactoring detection is crucial for a variety of applications and tasks:(i) empirical studies
about code evolution,(ii) tools for library API migration,(iii) code reviews and change …

Although testing effort estimation is a very important task in software project management, it
is rarely described in the literature. There are many difficulties in finding any useful methods …

Understanding the root cause of a defect is critical to isolating and repairing buggy behavior.
We present Causal Testing, a new method of root-cause analysis that relies on the theory of …

Regression test selection (RTS) aims to speed up regression testing by rerunning only tests
that are affected by code changes. RTS can be performed using static or dynamic analysis …

Regression test selection (RTS) speeds up regression testing by only re-running tests that
might be affected by code changes. Ideal RTS safely selects all affected tests and precisely …

Regression testing is an important part of the software development process but suffers from
the presence of flaky tests. Flaky tests are tests that can nondeterministically pass or fail …

Incremental and parallel builds are crucial features of modern build systems. Parallelism
enables fast builds by running independent tasks simultaneously, while incrementality saves …

Crowdtesting has become an effective alternative to traditional testing, especially for mobile
applications. However, crowdtesting is hard to manage in nature. Given the complexity of …

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 …

Regression testing is an essential software maintenance activity before the release of a new
version implementing a bug fix or a new feature. A regression test selection (RTS) technique …
