An Infrastructure for Mutation-based Evaluation of Testing Strategies

Software testing is an active field of research aimed at improving the quality of real-world software. Test suites, which are composed of test cases, are used to test software. Test cases are selected according to a testing strategy or test case selection criterion. New testing strategies and test case selection… Read more

Development of a Web-based Combinatorial Testing Framework

Combinatorial testing is a black-box testing approach that derives test cases from a model defined by the tester. This approach generates test inputs such that each combination, of n values from different parameters, is at least covered by one test case. Thereby, the size n of the combinations can be… Read more

Constructing Input Parameter Models from Sample Data

Black-box testing is nowadays unavoidable, especially when it comes to system or acceptance testing. The main problem in testing a function or system “completely” is the fact that testing the large number of possible input value combinations is practically unfeasible. One successful strategy to reduce the number of test cases… Read more

Generating Error-Constraints for Combinatorial Robustness Testing

Robustness constitutes an important characteristic of software components and systems. To evaluate this feature, the testing of negative scenarios is essential. Triggering error handling, however, might terminate the system under test before testing all values and value combinations of a negative test case. As a result, faults might remain undetected… Read more

Development of an Automated Combinatorial Testing Framework

Combinatorial testing is a sophisticated testing technique to reduce the amount of testing that would be necessary for exhaustive testing while still providing a similar value. It does so by specifying the coverage criterion, that all t combinations of input values of a system should be covered by a test… Read more

Usage-based Discovery of a Fragmentation for a Distributed Database

Fragmentation is an important aspect of the design of a distributed database (DDB). Many approaches exploit knowledge about the applications that are using the database (DB) to find the perfect split of the DB. Finding a fragmentation where this knowledge is not at hand can be difficult. However, if the… Read more

Framework for the technical layer in behavior-driven development

Framework for the technical layer in behavior-driven development Abstract Automated end-to-end tests allow to check the correct functioning of web applications but introduce effort for developing and maintaining the tests. The effort is increased when a core software is tailored to customer needs resulting in multiple variations. The scenario-based testing… Read more

Developing an Operator Framework for Kubernetes

Operators are a concept that allow the integration of application specific knowledge into Kubernetes. An operator extends the Kubernetes API by creating a custom resource and it’s implementation in form of a custom controller. The operator needs to be notified on changes of API objects in order to adjust the… Read more

State of the Art in Defensive Programming

Software is now important in almost all areas of society and is used by almost everyone everywhere. Dependence on software and the need for developers to secure their code is increasing very rapidly in times of growing cybersecurity threats. Errors can have serious consequences, which is why software needs to… Read more

Industrial IoT: Edge Device App Store & Digital Twins

Manufacturing companies need to be more efficient, productive and achieve new environmental standards while still providing low-cost products with regard to the competition. A digital production enables large-scale productivity gains, but also requires large amounts of data. As production environments are inherently heterogeneous it is often not easy to record… Read more
