I am looking forward to share my thoughts on ‘Reinventing Performance Testing’ at the imPACt performance and capacity conference by CMG held on November 7-10, 2016 in La Jolla, CA. Quite often the whole area of load testing is reduced to pre-production testing using protocol-level recording/playback. – Cloud.

Ultimately, quality gates safeguard code viability as it advances through the delivery pipeline. But how do they function in practice?

When you're working with any code, whether it's automation or software code, it should be treated the same way. One of the many things that don't come up as often when you're automating vs when you're building application code is testing. After-all, functions are still functions and variables are still variables.
