Imagine you are participating in an Automotive SPICE®assessment In your rote as a software tester, and you receive the Information that your process has been assessed with ''P" on process attribute PA1.1 at capability level 1. Which meaning it correct?
- A. You have NOT fulfilled capacity level 1.
- B. You have fulfilled capacity level 3.
- C. You have fulfilled capability level 1.
- D. You have fulfilled capacity level 2.
Answer: C
Explanation:
Explanation
In Automotive SPICE®, a rating of "P" on process attribute PA1.1 at capability level 1 indicates that the process has fulfilled capability level 1. In Automotive SPICE®, the assessment results are represented by a combination of letters and numbers, with "P" standing for "partially fulfilled." When a process is assessed with
"P" at a particular capability level, it means that the process has fulfilled some, but not all, of the requirements of that capability level. In this case, the software tester has fulfilled capability level 1 for process attribute PA1.1, which means that the basic requirements for that attribute have been met.

NEW QUESTION # 27
As a unit tester (.module tester'') you are working on a project and are supposed to develop a test strategy.
Which of the following test and analysis procedures is. according to Automotive SPIC®NOT an appropriate clamant of a verification strategy for unit tests (software units), which ware "manually coded"?
Note The components to verify are non-safety relevant and safely relevant (up to ASlL-C) components
- A. Tool supported static analysis
- B. Hardware-in-the-Loop-Tests
- C. Unit tests (Test of Software-Units)
- D. Code-Reviews
Answer: B
Explanation:
Explanation
According to Automotive SPICE®, Hardware-in-the-Loop-Tests (HIL-Tests) are not an appropriate component of a verification strategy for unit tests (software units) that are manually coded. HIL-Tests are used to test the interaction of the software system with the actual hardware to ensure the correct behavior of the system. However, these tests are not suitable for manually-coded software units and instead, verification strategies should include tools supported static analysis and code reviews. Unit tests (test of software units) are also an appropriate component of a verification strategy for manually-coded software units.
