On January, 11th 2017, our group member Xiaowei Wang successfully defended his PhD thesis. In the last years, Xiaowei worked on a new concept for reliability assessment and engineering of cloud systems. In contrast to related work, his concept is able to measure individual cloud component reliabilities and, based on this, to derive an assessment for the whole cloud system. His work showed, that his estimations are as good as measuring the reliability of the whole system at once. But his approach may also support predictions of the reliability of a cloud system after changes, which is left for future work.

There will be no office hours of Prof. Grabowski on 05. January 2017. In urgent cases, please contact studiendekan [at] informatik [dot] uni-goettingen [dot] de or studienberatung [at] informatik [dot] uni-goettingen [dot] de.

Our group member Patrick Harms took part in the competition "Verständliche Wissenschaft" organized by the Helmholtz-Zentrum Geesthacht, Centre for Materials and Costal Research. During this event, 8 researchers who finished their PhD in 2014 or 2015 presented their thesis topics in a way that is understandable for the broader public. Patrick became second best in the competition and we congratulate him for that. Further infos are available here.

We are happy to announce that our paper Are there any Unit Tests? An Empirical Study on Unit Testing in Open Source Python Projects  was accepted at the 10th International Conference on Software Testing, Verification and Validation (ICST 2017). The paper presents an empirical study on open source python projects to determine to what extent developers use unit tests in their development, and in what ways. The conclusions from the study are that while developers think they are developing a lot of unit tests, they are not actually doing so, and in fact, most projects have very few unit tests. Furthermore it shows, that mocking does not have much of an influence on the number of unit tests.
