CTFL-AuT ISTQB Certified Tester Foundation Level - Automotive Software Tester Questions and Answers

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.

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.

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.

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.

For integration tests SiL Mil and HiL test environments are suitable

For load and stress tests. MIL and HiL test environments are suitable

The correct classification of the test levels has no died influence on the safety relevance of the test object (with regard to ISO 26262).

For component tests, St and MiL test environments are suitable

Numerous internal signals of the test object can be stimulated or observed.

The test execution can be paused anytime for further analyses.

Electric error scenarios can be tested early.

In the SiL environment the simulation time is generally shorter than the real time.

The linking of requirements, test cases and test togs provides traceability and enables the desired verification of test cases for test case coverage

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

The linking of a requirement, a derived test case and the associated test implementation provides the base for a complete testability.

With complete tractably It Is possible to trace test cases to their requirements and test cases which have been executed to their corresponding results.

A MiL test environment, as the compiled software code can be Integrated cost efficiently into an environment model.

A Sal test environment, since the performance of the bus communication can be tested better in this test environment.

A hi test environment, as the bus communication with other participants can be tested dose to reality

Diagnosis functions and bus communications can only be tested In the vehicle.

An testing techniques are always applied to one test basis. The specific techniques, e.g. equivalence partition analysis, however, can always be applied.

ISO 26262 recommends specific testing techniques depending on the ASH level. Furthermore, the current state of technology must be considered

The risk assessment provides insights regarding the risks, whose causes will then be tested Intensively (independent of the testing technique).

For the selection and the applicability of the test techniques, the test basis is important, but not fie test level.

A wrapper is used as part of the testing with Software-in-the-Loop (SiL)

Software-m-the-Loop (SL) needs an Interface to the real vehicle or prototype.

With Software4rMhe-loop (SI), the tested software is implemented m a real control unit,

For Software-in-the-Loop (SIL). usually no specific hardware is used

A software architecture that fulfils the requirement of .testability

Test cases to check compliance with the MISRA-C:2012 coding standard

Test cases and test procedure for the verification and validation of the safety related requirements

Test cases and test procedures for production

MISRA-C defines rules and guidelines. Rules are verifiable by static analysis tools and are always required.

MISRA-C defines rules and guidelines that are supposed to help avoid anomalies In object-oriented developed software (e.g. in C++)

MISRA-C defines rules that include among others that the source code should not include nested comments.

A typical rule in MISRA-C is that the developer has documented the implemented behavior wen.
