What does the process of code-execution testing, black-box testing, and non-functional testing BEST describe?

The process of code-execution testing, black-box testing, and non-functional testing primarily describes verification, which refers to the activities that ensure a system is built correctly according to specifications. Verification includes confirming that the software system meets its requirements and requirements are correctly implemented without necessarily testing the end-user experience.

Code-execution testing examines whether the code behaves as expected under various conditions, ensuring that the implementation aligns with the specified requirements. Black-box testing focuses on the outputs generated in response to specific inputs without knowledge of the internal code structure, which is crucial for verifying that the software performs its intended functions. Non-functional testing assesses aspects such as performance, usability, and reliability, ensuring the product adheres to quality standards.

Validation, while related, emphasizes confirming that the product meets the user’s needs and requirements through testing in the real-world environment, which is a different focus from the act of verifying correctness through testing methods like those mentioned. Normalization typically relates to data organization within databases, and staging refers to the preparatory steps before final deployment, so they are not relevant in this context.
