TestingProactive Performance testing for each release. Load tests will discover the flaws and bottlenecks, the application or the systemPruebas de Rendimientomay have in production environment
AvailabilityConocer el escenario productivo para tomar una buena decisión sobre cómo orientar las pruebas de rendimiento esHigh availability of the application and the system is the goal of a ready for service status. The application and the systems must be stable ,La hipótesis de partida con más éxito.efficient and dimensioned according to the usage.
VelocityNot only the response time is important, an intelligent use of the resources is needed to grow in the future. Efficiency, understood ascapacity to dispose of the system resources to achive an objective, in our case response time and uptime
ScalabilityBeing able to grow depending on the necessities of the market, users and new technologies is one of the focus for a performance engineer
ScenariosA performance test is easy. It is easy to design non realistic scenarios. It is easy to collect irrelevant data. Even with a good scenario andAppropiate data, it is easy to use and incorrect statistic method to analysis the results.- Alberto Savoia
PreProductionOne of the most important parts of a good performance test design is to have an appropiate load test environment, as similar as possible toProduction at all levels, networking, systems and application architecture.
Otro título Monitoring EscenariosTo know the production environment is key to take good decisions about how to design a performance test plan. Designing a plan accordingTo real traffic and usage of the platform is key in creating validation criteria
Performance Teams Developers, DBAs, QAs, DevOps, product owners ... All the team is part of performance
Otro título ToolsThere are many tools available in the market for load testing and monitoring. An effort in evaluating these tools will benefit at long term theExecution of the tests. However, the most important part is how the reports are generated and who is going to interpret them.

Identify Reasons for Testing Performance Success Criteria • Application performance requirements and goals • Performance-related targets and thresholds • Exit criteria (how to know when you are done) • Key areas of investigation • Key data to be collectedTelefónica Digital 35Product Development & Innovation
Identify the Value Performance Testing Adds to the Project In general, the types of information that may be valuable to discuss with the team when preparing a performance-testing strategy for a performance build include: › The reason for performance testing this delivery › Prerequisites for strategy execution › Tools and scripts required › External resources required › Risks to accomplishing the strategy › Data of special interest › Areas of concern › Pass/fail criteria › Completion criteria › Planned variants on tests › Load range › Tasks to accomplish the strategyTelefónica Digital 36Product Development & Innovation

Identify and Coordinate Tasks Work item execution method Specifically what data will be collected Specifically how that data will be collected Who will assist, how, and when Sequence of work items by priorityTelefónica Digital 38Product Development & Innovation
Execute Task(s) Keys to Conducting a Performance-Testing Task • Analyze results immediately and revise the plan accordingly. • Work closely with the team or sub-team that is most relevant to the task. • Communicate frequently and openly across the team. • Record results and significant findings. • Record other data needed to repeat the test later. • Revisit performance-testing priorities after no more than two days.Telefónica Digital 39Product Development & Innovation
