NEW QUESTION 22
You are working as a .module tester* (syn. unit tester, component tester) in an automotive project for the development of a control unit for an electric window. During white-box lest design, you come atomic requirements: B1 AND (B2 OR B3). The task for you is to design test cases according to the principle of the modified condition/decision testing (MOOC). You have already designed three test cases:
1) B1 = TRUE, B2 = TRUE, B3 = FALSE
2) B1 = TRUE, B2 = FALSE, B3 = TRUE
3) B1 = FALSE, B2 = TRU, B3 = FALSE
Which of the following test cases is necessary to achieve 100% modified condition/decision coverage?
- A. B1 = FALSE, B2 = FALSE, B3 = FALSE
- B. B1 = FALSE, B2 = FALSE, B3 = TRUE
- C. B1= TRUE, B2 = TRUE. B3 = TRUE
- D. B1 = TRUE, B2 = FALSE, B3 = FALSE
Answer: C
Explanation:
Explanation
To achieve 100% condition/decision coverage, all possible combinations of the three Boolean variables B1, B2, and B3 must be tested. The three test cases provided only cover three of the eight possible combinations.
The fourth test case, C, covers the remaining combination of B1 = TRUE, B2 = TRUE. B3 = TRUE, ensuring 100% coverage.

NEW QUESTION 25
Which statement regarding the test levels In a test environment is true?
- A. For component tests, St and MiL test environments are suitable
- B. The correct classification of the test levels has no died influence on the safety relevance of the test object (with regard to ISO 26262).
- C. For load and stress tests. MIL and HiL test environments are suitable
- D. For integration tests SiL Mil and HiL test environments are suitable
Answer: A
Explanation:
Explanation
Component tests are done in SiL and MiL test environments because they allow the tester to observe the behavior of individual components of the system in isolation. This is important for ensuring that all components of the system work correctly and as expected.
NEW QUESTION 26
Which of the statements regarding traceability in Automotive SPICES®3.x is true?
- A. A1:N relation exists; for example If a test case is tested with the help of several requirements and is therefore linked to several requirements
- B. The linking of a requirement, a derived test case and the associated test implementation provides the base for a complete testability.
- C. With complete tractably It Is possible to trace test cases to their requirements and test cases which have been executed to their corresponding results.
- D. The linking of requirements, test cases and test togs provides traceability and enables the desired verification of test cases for test case coverage
Answer: C
Explanation:
Explanation
According to Automotive SPICES® 3.x, traceability is the ability to trace the relationship between two or more elements of the system. This includes traceability between requirements, test cases, test logs, and test results. With complete traceability, it is possible to trace test cases to their corresponding requirements and trace test cases which have been executed back to their corresponding results. This ensures that the system meets the requirements and that all tests have been carried out correctly and consistently.
NEW QUESTION 27
Which statement regarding the operating conditions and comparison of test environments is true?
- A. 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.
- B. The costs for debugging are higher for a Si test environment than for a MiL test environment.
- C. To lest m a MIL test environment, a full system specification is necessary.
- D. The proximity to reality in a MiL test environment is higher than In a SI test environment
Answer: A
Explanation:
Explanation
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. In MIL and SIL, the test object and the environment model must be defined in detail in order to create an accurate simulation of the real-world environment, so the test basis must include detailed information about the system and its components. In HIL, the test environment is more removed from reality, so the test basis does not need to be as detailed.
NEW QUESTION 28
Which constraints does a SiL test environment have?
- A. Numerous internal signals of the test object can be stimulated or observed.
- B. The test execution can be paused anytime for further analyses.
- C. In the SiL environment the simulation time is generally shorter than the real time.
- D. Electric error scenarios can be tested early.
Answer: D
NEW QUESTION 29
Which of the following options describes a relevant aspect of the design of a test environment for software-ln-the-loop (SIL)?
- A. A wrapper is used as part of the testing with Software-in-the-Loop (SiL)
- B. Software-m-the-Loop (SL) needs an Interface to the real vehicle or prototype.
- C. For Software-in-the-Loop (SIL). usually no specific hardware is used
- D. With Software4rMhe-loop (SI), the tested software is implemented m a real control unit,
Answer: B
Explanation:
Explanation
This is because the tested software must be implemented in the real control unit, and the interface is necessary to ensure communication between the software and the real vehicle or prototype.
NEW QUESTION 30
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. 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.
- D. 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.
Answer: A
Explanation:
Explanation
A closed-loop system is a type of control system in which the output of the system is used to regulate the input of the system. In this example, the output is the windscreen wiper activity, which is monitored and used to regulate the input, which is the activation of the ram sensor.

- B. Objective dimension
- C. Capability dimension
- D. Time dimension
Answer: C
Explanation:
Explanation
In principle, automotive SPICE® has two dimensions: the and the process capability dimension. The processes in the process dimension are based on the ISO 12207 that has been extended and modified with automotive-specific additions.
https://industryforum.co.uk/resources/automotive-spice-by-vda/#:~:text=Scope%20of%20Automotive%20SPICE The Capability dimension is defined in Automotive SPICE®. Automotive SPICE® is a model for the assessment and evaluation of software process capability in the automotive industry. The Capability dimension provides a description of the capability level of the software process, which is determined by the process capability maturity level (CMM) and the process capability level (PCL). The Capability dimension includes aspects such as the definition of processes, the availability of resources, the measurement and analysis of processes, and the improvement of processes.
