Which example describes a typical application of a closed-loop system?

• A.The correct reaction of the windscreen wiper is to be tested To do so. the ram sensor Is activated by water on the screen and the windscreen wiping activities are monitored.
• B.A cruise control is to be tested by reaching me target speed In a given time and holding this speed despite outside disturbances. Different driving scenarios are simulated for this.
• C.Activating the hazard warning lights is to be tested To do so. the flashing lights are monitored and the flashing frequency is measured and assessed.
• D.The setting of an error memory entry in the motor control unit Is to be tested To do so, the motor temperature is Increased above the critical limit and afterwards, the subsequent error memory entry will be read and assessed.

Which statement regarding requirements-based testing is true?

• A.Only extensive and delated requirements can be covered completely by the tester.
• B.Requirements-based testing is a testing technique
• C.Requirements-based testing can be combined with other lest practices or testing techniques.
• D.Requirements-based testing can solve issues like complete requirements

Which statement regarding the design of a MIL test environment Is TRUE?

• A.The test environment includes a real time capable computer, which can capture ail relevant signals r time
• B.To execute the tests, the tester needs a computer and the correspond^) simulation software, including the environmental model.
• C.Interface and integration tests are two test types or test levels that can only be applied in a Mil test environment.
• D.In the MIL test environments, the simulation time runs in real time because the software is running on real hardware.

Which statement regarding the operating conditions and comparison of test environments is true?

• A.The proximity to reality in a MiL test environment is higher than In a SI test environment
• B.The costs for debugging are higher for a Si test environment than for a MiL test environment.
• C.As tests for MIL and SIL take place closer to the test object, the test basis must have a higher degree of detail than In HIL.
• D.To lest m a MIL test environment, a full system specification is necessary.

Which of the following options describes a relevant aspect of the design of a test environment for software-ln-the-loop (SIL)?

• A.For Software-in-the-Loop (SIL). usually no specific hardware is used
• B.Software-m-the-Loop (SL) needs an Interface to the real vehicle or prototype.
• C.A wrapper is used as part of the testing with Software-in-the-Loop (SiL)
• D.With Software4rMhe-loop (SI), the tested software is implemented m a real control unit,
