Abstract: An electronic arrangement for analyzing a model-based testing scenario relating to a system under test (SUT), includes a model handler entity for obtaining and managing model data indicative of a model intended to exhibit the behavior of the SUT, a test plan handler entity for obtaining and managing test plan data indicative of a number of test cases relating to the model and expected outcome thereof, a test execution log handler entity for obtaining and managing test execution log data indicative of the execution of the test cases by the test executor and/or SUT, a communications log handler entity for obtaining and managing communications log data indicative of message traffic between the test executor entity and SUT, and an analyzer entity for detecting a number of failures and their causes in the model-based testing scenario on the basis of model, test plan, test execution log and communications log data.
