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.

Giving better functional test coverage as the code is tested on a wide range of combinations. Running these tests in sequence can be time-consuming, as you’d wait for one test to complete before running other tests.

Organizations can customize quality gate criteria to validate technical service-level objectives (SLOs) and business goals, ensuring early detection and resolution of code deficiencies. Ultimately, quality gates safeguard code viability as it advances through the delivery pipeline. But how do they function in practice?

To ensure high standards, it’s essential that your organization establish automated validations in an early phase of the software development process—ideally when code is written. Validation tasks are then extended left to cover performance testing and release validation in a pre-production environment.

Why do we run Performance Tests on commits? What are the Performance Tests? Ideally we catch regressions before they even reach the main branch.

What if there was a way that you could prevent performance from degrading in the first place? Some sort of performance gateway that only allows changes to production code if they meet performance requirements? I think it's time we talked about having performance regressions break the build.
