Hosting Workshop

Understanding performance complexity: the case for introducing principles of functional testing to performance.

Testing complex applications rigorously for performance traditionally involves executing a high number of repetitious tests, using low variety test data. However, the goal of performance testing should be to exert realistic behavior. That means reflecting the full range of scenarios that could occur in production, at the full range of possible workloads. This interactive workshop will discuss how automated Load testing can cut across multi-tier architecture and the testing pyramid, generating rigorous tests and data to validate both performance and functionality. It will begin by presenting a technique where Load and functional tests are automated and maintained from the same central models, testing rapidly and rigorously across the UI, API, and database layer. The session will then lead into an open and interactive discussion of the approach, drawing on the range of experiences in the room.
