iSQI CTFL-AuT - ISTQB Certified Tester Foundation Level - Automotive Software Tester

ISTQB-certified Testers are expected to adhere to standards when performing testing activities, ensuring that the project stakeholders have a shared understanding of the testing process and can communicate effectively. This helps to reduce confusion and ensure that the project is managed in an organized manner. Standards also help to ensure that the testing process is repeatable, making it easier to identify defects and optimize the process over time.

Databases are used to store information about input and output signals, and to define the implementation of a communication protocol, but they do not describe the signals of a communication channel. ASAM-standards are used to describe the technical interfaces of automotive systems.

One of the most effective ways of dealing with the increasing complexity of product development is through the use of several models as variants of a common platform. This strategy allows for a more efficient use of resources, as the base platform can be used and adapted for a variety of different products. Additionally, this strategy allows for more efficient testing, as the same tests can be used for multiple products. This approach also makes it easier to identify and fix any issues that may arise, as the same codebase can be used for multiple products.

In a MIL test environment, the simulation software runs on a computer, and the environmental model helps to accurately simulate the real-world environment in which the system will run. The tester also needs to be able to control and monitor the system, and interface with the simulation software.

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).

There are four ASILs identified by ISO 26262―A, B, C, and D. ASIL A represents the lowest degree and ASIL D represents the highest degree of automotive hazard.

According to Automotive SPICE®, a Test Procedure Specification is required. The Test Procedure Specification is a detailed document that describes how a particular test case will be executed and what the expected results are. It is an essential part of the software testing process and provides a clear understanding of the testing approach and the scope of testing. The Test Procedure Specification is used by testers to ensure that the test cases are executed consistently and correctly, and it provides a reference for evaluating the test results.

A Hi test environment is the best choice for testing diagnostic functions and bus communications on the CAN bus, as it is the most realistic test environment and allows for the testing of the bus communication with other participants. Hi test environments are also the most cost-efficient solutions for testing these types of functions due to the availability of realistic, cost-efficient environment models.

ISO 26262 recommends specific testing techniques depending on the ASIL level. Furthermore, the current state of technology must be considered. ISO 26262 is a standard for functional safety in the automotive industry, and it recognizes several context factors that influence the selection of testing techniques. Specifically, the standard recommends specific testing techniques depending on the Automotive Safety Integrity Level (ASIL) of the system, as well as considering the current state of technology. This means that the risk assessment provides insights regarding the risks, but it is the ASIL level and the current state of technology that will determine the specific testing techniques to be used.
