ISO 26262 is based on an integrated safety lifecycle approach, which includes the specification, design, implementation, verification and validation of safety-relevant systems.

MIL stands for "Modified In-Loop" and describes a test environment in which stimulations and observations of the test object are possible anywhere via access points. This means that no environmental model is necessary and the test object is available in readable code. Additional hardware is usually not necessary for MIL test environments.

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.

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.

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.

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.
