The Analysis, Testing, Slicing, Search and Transformation (ATeSST) group, which is jointly led by Mark Harman and Rob Hierons, focuses on formal elements of Software Engineering that contribute to the development of robust, efficient, reliable, and correct systems. The work considers the use of formal analysis in:

The work of the ATeSST group is funded, in part, by grants from DaimlerChrysler AG, the EPSRC and the Leverhulme Trust.


Group members

The ATeSST group is linked to the VASTT group.

Projects

GUided Slicing and Targeted Transformation (GUSTT)

GUSTT is an EPSRC funded project concerned with algorithms and applications of amorphous slicing. More details are available on the GUSTT page.

Formal Methods and Testing (FORTEST)

FORTEST is an EPSRC funded network that is investigating the relationships between formal (and semi-formal) methods and software testing. FORTEST considers a number of problems such as the (automatic) generation of efficient and effective tests from a formal or semi-formal specification and approaches that combine testing and proof. More details are available on the FORTEST page.

Software Engineering using Metaheuristic Innovative Algorithms (SEMINAL)

This EPSRC funded network aims to apply search techniques, such as genetic algorithms, simulated annealing and tabu search to problems typically encountered in the domain of software engineering. More details may be found on the SEMINAL web page.

Testability Transformation (TeTra)

TeTra is an EPSRC funded project that aims to improve software testability using transformations. The transformations to be used are novel because they need not preserve traditional notion of equivalence. In the conventional sense they are not therefore meaning preserving transformations. However, they are adequate test set preserving. The approach is also novel because the transformations are not an end but a means to an end; once the test data is generated, the transformed program can be discarded. A few details are available on the TeTra page.

Testability Transformation

Evolutionary testing is hard in the presence of side effects, unstructuredness and flag variables. This project aims to investigate ways in which program transformation can overcome these barriers to evolutionary program testing. The Testability Transformation project, funded by Daimler, led to the TeTra project, funded by the EPSRC.

Testing State Based Systems (TESTBASE)

TESTBASE, which is funded by the Leverhulme Trust, will investigate ways of rewriting state-based specifications in to aid testing. In particular, it considers the problem of transforming a state-based specification in order to simplify the problem of finding a set of feasible paths that, between them, satisfy some test criterion.

Vada

Vada is funded by DaimlerChrysler. Evolutionary testing effectiveness is reduced by large search spaces. Some variables which are apparently members of the search space, because they are input variables, do not contribute to the computation under test. Variable Dependence can identify these variables. This project aims to implement a dependence-based tool, Vada, for search-space reduction.
