Answer: A
Explanation:
Explanation
The International Software Testing Qualifications Board (ISTQB) Certified Tester, Automotive Software Tester (CT-AUT) study guide states that the following test levels are equivalent: component test (CTFL), software unit test (ISO 26262.6-9) and software component verification (ASPICE. SVYE.4). ISO 26262 and ASPICE both use the term 'system' to refer to a product consisting of a hardware and a software component.
ISO 26262 does not have an equivalent for system testing (CTFL), and ASPICE does not have an equivalent for safety validation (ISO 26262.4-9) and system integration test (ASPICE SYS.4).

NEW QUESTION # 32
Which statement regarding the operating conditions and comparison of test environments is true?
- A. To lest m a MIL test environment, a full system specification is necessary.
- B. The proximity to reality in a MiL test environment is higher than In a SI test environment
- C. The costs for debugging are higher for a Si test environment than for a MiL test environment.
- D. 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.
Answer: D
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.
