摘要
The invention relates to an operational test device and a method of executing an operational test for a test system which can assume a number of operating states. A test case generator (TCG) is provided for generating a number of test cases which are sent via a test device interface (INT) to the system under test (SUT). A test state model of the test system is ascertained by a test state model generator (TSTM-G) from information on the hardware configuration of the test system (SUT), information on the possible operating states of the test system (SUT), information on the test commands necessary for bringing about changes in operating state within the test system (SUT), and from traffic values which indicate transitional probabilities ascertained in the test system's real application for the operating states. Test commands are generated on the basis of a Monte-Carlo simulation of this test state model. The operational test device is particularly suitable for use with a Petri net state model for testing a telephone network or in particular a mobile telephone network, such as a GSM network, e.g. for interrupting connection lines therein.
