We can help you build a better software system

Peformance, Scalability and Reliability (PSR) Testing

People depend heavily on software. If the software does not meet the functional or performance requirements, then unexpected behaviors occur in the system. Saying "It's a feature" does not help in the case of severe functional problems. Based on CNET 3.4 Billion was spent on the Y2K bug alone. All "bugs" cannot be elimnated but they can be drastically reduced through continuous test integration. Similar to the way a garden that has weeds pulled and bugs removed daily will have less of chance for rotten fruit, a software system that has performance and functional tests run against it regularly will have less of a chance for rotten user experiences. And, it basically comes down to a cost of quality issue. How important is it that you know how well your software is tested? How important is it that you know your software can handle the peak load on the system?

Testing	Application Development	Process
Mercury ProfilerProfile applications to find the worst performing methods and queries while finding memory leaks. GrinderGenerates virtual users against a web based application to measure the application under load Data mining for simulationsDiscover actual simulation parameters for load testing applications by mining databases and log files. Unit testing with Httpunit, Junit and SeleniumTest JAVA based application at the database layer with DBUnit, logic layer with Junit and web layer with HttpUnit and Selenium. Performance monitoringUse perfmon on windows machines to monitor the physical hardware performance during testing and deployment Regression and Load Testing StrategiesUse continuous integration with Selenium, Grinder, HttpUnit and Junit to continuously run tests against the application for performance and correctness.
