3 Testing with TPT 1 Test modeling 2 Test execution 3 Assessment + Reporting???? assessment description test results Tester Test modeling fully automated Test assessment Test documentation scenario description data logs platform specific TPT Virtual Machine Platform adapter Test execution 3

4 Motivation Testing control systems requires special features. Folie 4

5 What makes automotive testing special? Feature 1: Tests must be portable and reusable between the integration levels and technologies. Modeling Coding / Code Generation Target MC Integration ECU Integration Car Integration Functional refinement Objective: Test refinement, instead of test rewriting! Folie 5

6 What makes automotive testing special? System under Test Feature 2: Tests must handle signals, parameters, and diagnosis in a simple way. Stimulation Data tables, recorded data, parameter sets Test Case Behavior Folie 6

7 What makes automotive testing special? System under Test Feature 2: 3: Tests Tests must must be able handle to react signals, to system behavior parameters, online and (closed-loop diagnosistests). in a simple way. Stimulation Test Case Behavior Observations Data Expressive tables, closed-loop recorded data, test parameter models sets Folie 7

8 What makes automotive testing special? System under Test ECU Feature 4: Tests must be real-time enabled. Real time! Stimulation Real time! Test Case Behavior Observations Folie 8

9 What makes automotive testing special? System under Test ECU Feature 5: Tests must handle data from different sources. Stimulation Test Case Behavior Observations MCD-3 Folie 9

10 What makes automotive testing special? System under Test ECU Feature 6: Test results should be evaluated automatically based on the requirements. Stimulation Test Case Behavior Observations??? Folie 10
