Understanding difference of System Or Architecture-based software testing & statement level testing. Unit level Test coverage cannot apply for system tests.
Benchmarking Storage systems(Block, File, object) is complex because of large number of interaction between I/O devices, caches, kernel daemons, monitors, OS, Application software layers, networking. The complexity of performance benchmarking exponentially increases for large scale SAN, NAS Cloud, HPC & MPP(Massively Parallel processing) solutions. Big Data, Machine Learning & AI applications are pushing for real […]
The important questions, my dear Watson is “What to measure”, “With what to measure”, “How to measure” & “How to report”. Measurements are vital and represent the basis for workload characterizations. The above questions are important to evaluate a system’s performance, its characterics, HW/SW interactions and request processing against workloads. Performance characterizations against workload measurements, […]

An estimated $70B is spent annually testing applications for functionality, performance and security, requiring over 2 billion manhours. Nearly all of that $70B spend is on people costs, and less than $3B is spent on test automation tools.
