Neotys PAC - Wilson Mar

Neotys organized its first Performance Advisory Council in Scotland, the 14th & 15th of November.
With 15 Load Testing experts from several countries (UK, France, New-Zeland, Germany, USA, Australia, India…) we explored several theme around Load Testing such as DevOps, Shift Right, AI etc.
By discussing around their experience, the methods they used, their data analysis and their interpretation, we created a lot of high-value added content that you can use to discover what will be the future of Load Testing.

From Change To Mindsetchanges Testing efforts like cops writing traffic tickets Shift Left Test-first to build-in quality while coding Server operations like guards limiting access Self-service Server operations as enablers, trainers, and helpers People inspect code Automation People automate inspection Programs are hand-coded and static Code gen. Code generated from computer-readable requirements (Swagger, JHipster) Each specialist separately analyze own data Integrated reporting Detect trends & anomalies across versions & environments & initiatives People periodically reacting to lines on graphs Intelligent Alerts Predictive alerts from constant scans of all environments
  12. 12. 16 Communities of Practice
  13. 13. Technologyinitiatives A. package managers for reuse of code B. deploy scripts – Bash/PowerShell/Ansible for automating file movement C. server config. – Ansible/Puppet/Chef/uDeploy for custom settings D. build jobs – Jenkins/Hudson/Bamboo for initiating work pipelines E. local unit tests – xUnit for asserting conditions around lines of code. F. UI automation - Selenium to mimic people click and typing G. team source repository - GitHub/GitLab to store text code H. team integration tests to identify whether pieces work together I. binary repository - Nexus/Artifactory to avoid duplicate work J. code quality review – SonarQube, Fortify for team to focus on issues K. code coverage – Cobutura/etc. L. stress/load scripting – LoadRunner/NeoLoad to impose stress M. alerts from monitoring – CA-APM to identify root causes of bottlenecks N. visualization from time-series analysis to identify trends O. codegen from specs – Swagger/RAML https://wilsonmar.github.io/ci-cd/
