Synergies and differences in the testing phase

Verification testing takes place at multiple stages of the development process, starting with the unit level, then the component level, and ending at the system level. A system developed according to ISO 26262 is expected to achieve a high level of quality assurance through testing rigor in proportion to the system safety integrity level. These test methods reinforce the quality argument of the system by verifying the correctness of the unit design and implementation, and the ability of the integrated system components to achieve the system objectives. One example test method defined by safety engineering is boundary value and equivalence class-based (BVEC) testing. BVEC testing involves testing the software system with values that are at the boundaries of the input domain or just outside of it to detect improper software responses. BVEC testing aims to identify any errors or exceptions that occur at the boundary values of input domains...
