It is no more sufficient that the software delivered is functionally correct. It is expected that the software can handle the real life load and deliver good performance. Additionally it is expected that we know the limits of the software (stress) and whether it can scale well. Hence it is becoming increasingly important that we perform Load, Stress, Performance and Scalability (LSPS) tests on the software. How do we work?We focus on performance validation (includes load, stress, scalability tests) to assess key non-functional aspects of the software. This includes devising strategy / plan, designing tests, automation and assessment reporting.Our test lab is fully equipped to perform certain specialized non-functional tests that are critical and mandatory before software release but cannot be performed manually. Load / Stress / Performance / Scalability testing, and others like Volume testing, Reliability testing and assessment, Installation testing, Usability testing, Configuration / Compatibility testing, Internalization testing.Our work on Performance validation has included areas of Elearning applications, Logistics software, Auction framework, Banking system. Success StorySTAG's evaluation of a eCommodity finance application for load, performance, and scalability among concurrent users for an IT services company ensures successful deployment of the product at a leading commercial bank in India.STAG certifies an eLearning product 'deploy-ready' after extensive LSPS evaluation, enabling our partner to successfully deploy it at the world's largest publicly funded health services organization.
