Performance Testing Interview Questions and Answers

In software package engineering, performance testing is generally, a testing observes performed to see however a system performs in terms of responsiveness and stability under a selected work. It may serve to investigate, measure, validate or verify different quality attributes of the system, equivalent to measurability, reliability and resource usage.

Performance testing, a subset of performance engineering, is a computer science practice which strives to build performance standards into the implementation, design and architecture of a system.
