MISRA-C defines rules and guidelines. Rules are verifiable by static analysis tools and are always required. MISRA-C:2012, also known as the Motor Industry Software Reliability Association (MISRA-C) C Coding Standard, is a set of coding rules and guidelines that are designed to help ensure the safety and reliability of software written in the C programming language. MISRA-C defines rules and guidelines that are intended to help avoid anomalies in code, such as buffer overflows and incorrect pointer manipulation. Rules are verifiable by static analysis tools, and are always required. Guidelines are best-practice recommendations, and are not always enforced.

The tester always takes the overall context of the product development into account when she/he executes their tasks. This means that the tester is responsible for ensuring that testing is performed in a way that takes into consideration the wider context of the product development, such as safety issues, system reliability, usability and other factors. This helps to ensure that the product is safe and reliable for the end user. Source: ISTQB Certified Tester, Automotive Software Tester (CT-AUT) Study Guide.

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.

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.

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.
