What do you call the method used to test how quickly certain features run on a system?

The method used to test how quickly certain features run on a system is known as a performance test. Performance testing focuses on evaluating the speed, responsiveness, and stability of a system under a particular workload. It measures various metrics, such as response time, throughput, and resource usage, to ensure that the system meets specified performance criteria.

In contrast, a logic test is primarily concerned with the correctness of the algorithms and the logical flow of the program, focusing on whether the expected output is achieved for given inputs. A syntax test evaluates the code for grammatical correctness and proper use of programming language syntax, helping to identify errors before execution. A presence test checks for the existence of certain elements, like files or database entries, rather than measuring performance metrics. Thus, performance testing specifically addresses how well the system performs, making it the most suitable term for this context.
