Abstract
|
|
A large percentage of enterprise applications are still failing to meet their performance expectations when deployed to production environments, despite having better tools. In my experience working with large-scale projects at Fortune 500 companies, the primary reason for this failure is that performance testing and tuning are often performed too late in the application development lifecycle. Tools can’t fix that. What is needed is a way to bring performance management into the development process – enter Continuous Performance Management (i.e. continuous performance testing).
|
| Many best practices and methodologies are helpful, but only address part of the overall software development lifecycle. For example, from Test-Driven Development we learned to functionally test our applications during development – from Continuous Integration we learned to integrate and test our applications on each developer commit. |
|
We have found that if we combine both of these methodologies, we can start performance testing earlier in the process and automate it. This session describes the process of integrating performance unit tests, performance integration tests, and even performance load tests into an automated Continuous Integration environment. As Test-Driven Development helps reduce functional bugs from an application and Continuous Integration renders integration as a non-issue, we build on that foundation to show how Continuous Performance Management allows developers to take control of the performance of their application and resolve problems early when they are manageable.
|
| This session will show the processes and methodologies required to realize this goal as well as technically how to assemble a working solution. Sample technologies include JUnit/XUnit, Ant, CruiseControl, JMeter, and profiling and diagnostic technologies such as JProbe and PerformaSure, but can be applied to any applicable product set. Attendees should be intermediate or advanced Java developers. |
