Pythia: A regression test selection tool based on textual differencing
Regression testing is a commonly used activity whose purpose is to determine whether the modifications made to a software system have introduced new faults. For many large, complex, software systems the retest all strategy is not practical: the resources required to reexecute and verify all available test cases (i.e., time and human effort) are prohibitive. Ad hoc methods are not desirable, as ...
متن کاملOrigin Tracking + + Text Differencing = = Textual Model Differencing
In textual modeling, models are created through an intermediate parsing step which maps textual representations to abstract model structures. Therefore, the identify of elements is not stable across different versions of the same model. Existing model differencing algorithms, therefore, cannot be applied directly because they need to identify model elements across versions. In this paper we pre...
متن کاملSpectral Differencing with a Twist
Spectral collocation methods have become very useful in providing highly accurate solutions to differential equations. A straightforward implementation of these methods involves the use of spectral differentiation matrices. To obtain optimal accuracy these matrices must be computed carefully. We demonstrate that naive algorithms for computing these matrices suffer from severe loss of accuracy d...
متن کاملFunctional Differencing
In nonlinear panel data models, the incidental parameter problem remains a challenge to econometricians. Available solutions are often based on ingenious, modelspecific methods. In this paper, we propose a systematic approach to construct moment restrictions on common parameters that are free from the individual fixed effects. This is done by an orthogonal projection that differences out the un...
متن کاملRT-Selection : A Regression Test Selection Technique Using Textual Differencing and Change Impact Analysis
Regression testing intended to provide confidence that newly introduced changes do not obstruct the behaviours of the existing and unchanged parts of the software. One of simple and basic regression testing techniques is retest-all, but it requires lot of time and cost. The regression test selection technique selects a subset of previous test cases to retest the changed software. It, therefore,...
