Testing the Continuous Behavior of Embedded Systems
نویسنده
چکیده
The test of embedded systems is well-supported by a number of different test methods and tools if the system under test displays a discrete behavior. However, for systems with continuous behavior these approaches are not appropriate. Practical experiences with the test of embedded systems in the automotive industry have revealed that testing the continuous behavior is different from testing discrete systems. In this paper, we discuss the reasons for the specialities of continuous behavior testing and the consequences for practicing testers. In addition, we introduce a new test approach that enables the systematic definition of executable test cases for testing the continuous behavior of automotive embedded systems. This method is already in use in several production-vehicle development projects at DaimlerChrysler and is based on a graphical notation for test cases which is easy to understand but also powerful enough to express complex, fully automated tests as well as reactive tests of continuous behavior.

متن کاملAutomated Testing of Real-Time Tasks
The development of embedded systems is a crucial area of responsibility in industrial practice. Many embedded systems need to meet real-time requirements. This adds a new dimension to the testing of such systems – not only the logical behavior, but also the temporal behavior of these systems requires thorough testing. In comparison with conventional software systems, the testing of embedded sys...
