Embedded Systems Testing Benchmarks Site


Welcome to the
Embedded Systems Testing Benchmarks Site

This site has been created on 2011-05-23 and will be continuously updated and maintained by the research team AGBS - operating systems and distributed systems at the University of Bremen, Department of Mathematics and Computer Science FB3.


The Embedded Systems Testing Benchmarks Site will provide benchmarks for automated model-based testing (MBT) tools. A suggestion how to structure these benchmarks has been published in

Basically, the components of a MBT benchmark are

  • a formal model from where automated test cases and test data should be derived,
  • a test suite that has been generated by means of a reference tool and
  • benchmark evaluation data associated with the tool and the test suite.
As suggested by the authors in [1; Section 4], benchmarks for model-based testing should be structured into two sub-classes.
  • Test strength benchmarks investigate the error detection capabilities of concrete test cases and test data generated by MBT tools.
  • Test generation benchmarks input formal specification of test cases (symbolic test cases according to the terminology used in [1]) and measure the time needed to generate concrete test data.
The first benchmark is provided by the researchers listed above; it also serves as an example of how other contributions should be structured.


  • Turn Indicator Model Rev. 1.6 (last update: 2014-04-17)
    This model is currently used by Daimler for system tests of functionality related to the turn indicator lights. An introductory overview over the model is given in [1] above; more detailed explanations are contained in the model itself, in the form of notes.
  • Model Based Testing from Controlled Natural Language Requirements (last update: 2013-09-16)
    These benchmarks are currently elaborated here to present extensive material for model-based testing against (controlled) natural language (CNL) requirements: specifications written in natural language style are parsed and evaluated with respect to their behavioural semantics. From this evaluation a formal model is created in an automated way, so that the principles, algorithms and tools of model-based testing can be applied to create test cases and test oracles verifying systems directly against their requirements. The purpose of this approach is to allow for application of model-based testing in early phases of a project, where detailed formal test models - e.g. like the one made available above - are still under construction.

    The material on CNL testing currently made available complements the article Model Based Testing from Controlled Natural Language Requirements submitted by the authors Gustavo Carvalho, Flavia Barros, Florian Lapschies, Uwe Schulze, and Jan Peleska to the FTSCS 2013, Second International Workshop on Formal Techniques for Safety-Critical Systems.

  • Ceiling Speed Monitoring Model Rev. 1.0 (last update: 2014-05-11)
    The ceiling speed monitoring model is a functionality of the European Vital Computer EVC, the on board controller that is described in the public European Train Control System ETCS specification. The ceiling speed monitoring is a part of the speed and distance monitoring function that ensures “... the supervision of the speed of the train versus its position, in order to assure that the train remains within the given speed and distance limits.” [UNISIG. ERTMS/ETCS SystemRequirements Specification, Chapter 3,sec. 13.1.1]. This particular sub-function supervises the observance of the maximal speed allowed according to the current most restrictive speed profile (MRSP).
