TOCSYC - Testing of Critical System Characteristics (KKS)



Start date:


End date:


The TOCSYC research environment will combine five Swedish groups in software testing research to advance the knowledge of testing critical characteristics of complex embedded systems. The overall goal of TOCSYC is to enable and support cost-effective testing for critical characteristics in embedded systems by providing Swedish industry with new and improved tools and techniques for efficient and effective testing as well as the decision-support procedures necessary to select the right testing tools or techniques for their context.

In order to meet this goal, TOCSYC has identified four objectives that impose key research challenges:

  • develop feasible testing techniques that address characteristics, such as performance efficiency, robustness, and testability which all are critical to complex embedded systems,
  • determine the cost effectiveness of different test techniques, 
  • automation of complex testing activities, for example generate and prioritize test cases and determine verdicts of test executions, and 
  • establish ways to assess and increase testability of software under test 

TOCSYC will advance research in software testing by developing and combining techniques for model-, search- and mutation-based testing in order to target performance efficiency and robustness aspects. Static analysis techniques will be developed to support testing by e.g., model-extraction. Testability issues will be targeted in order to further support testing of performance efficiency and robustness.
