Test Harness Variable = client param, app param, system param. V. V. Main Point(s): Be able to identify these components very early in the project, because they allow you to scope the effort. Outline: I.A. Terms and definitions. Script:: In standard QA tests, we apply a known input to the system, and determine whether the output is correct. In performance tests, we aren\u2019t concerned about the input or output content, but rather the pattern of the flow and the rate of arrival. We will use the techniques of the Scientific Experimental Method to control, run and measure each performance test. Don\u2019t get too ambitious \u2013 it\u2019s easy to expand scope later, but starting with a very complex System Under Test can jeopardize your ability to get in enough test iterations to draw meaningful conclusions. But never lose track of the thread that connects the tests you are running with the real business costs, benefits and risks you are there to evaluate. Latency = ReceiveTime \u2013 SendTime. Test Components External. Components Expert Tip: Limit scope to those test components that. are critical to performance and under your control.
