µTTCN - an approach to continuous signals in TTCN-3
نویسندگان
چکیده
Today, development and implementation of automotive embedded systems is based on a model-based process. A major problem of respective model-based toolchains can be traced back to inadequate testing tools, which often are not standardized, incomplete and cumbersome in usage. Due to these shortcomings, test specifications are neither exchangeable nor reuseable. In this paper, we propose μTTCN for test specifications of continuous embedded systems. μTTCN targets at exchangeable and reuseable test specifications based upon TTCN-3, as well as convenient handling of testcase implementations.

Modeling Property Based Stream Templates with TTCN-3
Test evaluation and test assessment is a time consuming and resource intensive process. More than ever this holds for testing complex systems that emanate continuous or hybrid behavior. In this article we introduce an approach that eases the speci cation of black box tests for hybrid or continuous systems by means of signal properties applied for evaluation. A signal property allows the charact...
متن کاملTesting Embedded Control Systems with TTCN-3 An Overview on TTCN-3 Continuous
TTCN-3 has gained increasing significance in recent years. Originally developed to fit the needs for testing software-based applications and systems in the telecommunication industry, TTCN-3 has shown its applicability to a wide range of other industrial domains in the mean time. TTCN-3 provides platform-independent, universal and powerful concepts to describe tests — especially for discrete, i...
متن کاملReal-time test specification with TTCN-3
In this paper we propose an extension to the third edition of the Tree and Tabular Combined Notation (TTCN-3) to support realtime testing. Our approach is based on the separation of functional and real-time requirements in the test specification. Functional requirements are defined in form of stimuli and expected responses, i.e., in form of functional TTCN-3 test cases, and real-time requiremen...
متن کاملImplementation of TTCN-3 Test Systems using the TRI
This paper discusses the implementation of test systems, which are specified based on TTCN version 3 (TTCN-3). TTCN-3 has recently been standardized by [4] European Telecommunications Standards Institute (ETSI) as a new test specification language beyond protocol testing. TTCN-3 source code however only constitutes the first step in a TTCN-3 test system implementation. A complete test system im...
متن کاملFrom U2TP Models to Executable Tests with TTCN-3 - An Approach to Model Driven Testing
The approach towards system engineering according to Model-Driven Architectures (MDA) with code generation derived from model implies also an increased need for research on automation of the test generation process. This paper presents an approach to derive executable tests from UML 2.0 Testing Profile diagrams automatically. In particular, an approach to derive executable tests within the Test...
