This task describes how to define the load test objectives as part of the load test planning process.
State the objectives in measurable terms
Once you decide on your general load testing objectives, you should identify more focused goals by stating your objectives in measurable terms. To provide a baseline for evaluation, determine exactly what constitutes acceptable and unacceptable test results.
General Objective. Product Evaluation: choose hardware for the Web server.
Focused Objective. Product Evaluation: run the same group of 300 virtual users on two different servers, HP and NEC. When all 300 users simultaneously browse the pages of your Web application, determine which hardware gives a better response time.
Decide when to test
Load testing is necessary throughout the product life cycle.
