Can it be said that quality testing is related to compliance verification or to confirming the correctness of the system?

Quality testing is related both to verifying compliance with requirements and confirming the correct operation of the system.

• Requirements compliance check (validation) means that the product meets the expectations and specifications of the customer.
• Confirmation of correct operation (verification) means that the system functions correctly according to technical specifications.

Thus, quality testing covers both aspects, ensuring that the product not only operates without errors but also meets the stated requirements.
