Little's law based validation framework for load testing.

Context: Performance is a key quality consideration for large-scale software systems which supports thousands of concurrent users. Load testing is an integral part of the development lifecycle and is used to address performance issues before deploying the system in production. But, how do we validate the output reported by load testing tools? Little’s Law is useful for validating the accuracy of load testing output. Though IT industry is flooded with various enterprise and open source tools for load testing, but they do not offer support for validation of its result using Little’s Law. Manual validation is time intensive and infeasible with increase in the complexity of testing scripts.
