Typically, the manufacturers’ recommendations are well founded, and only very experienced implementers, or those who wish to experiment, should mix and match various...

Performance testing (PT) is not to be construed as features testing even though it has a definite link with the latter. In fact, PT begins from where the feature testing ends. It presupposes successful completion of features testing, meaning that all the desired functional requirements expected from...

The core theme of the previous chapters is that a methodical and structured approach to PT is rather necessary right from the early phases of the development cycle. This will ensure predictability and controllability of application performance in practice. The preparatory activities associated with PT...

The focus of Chapter 4 was on the planning and definition phase of PT while this chapter provides an in-depth view of the test design phase. All the necessary inputs for PT are captured under the test definition phase. These inputs are the building blocks for the design phase of PT.

The next phase, that is, the build phase, commences after the completion of the design phase. Design provides the guidelines, but the build phase really implements the design so that execution of the test can be carried out later. The first activity in the build phase is to plan the various activities...
