The Future of Performance Testing

Alex Podelko

While there are still quite a lot of cases where it is still applicable, it needs to evolve into more sophisticated processes tightly integrated with development and other parts of performance engineering. First of all, integrating into agile development (shift-left / continuous performance testing) and integrating into performance information loop with production (shift-right) to form a holistic performance view.
